Cells must obtain essential molecules from their environment (such as oxygen and glucose), and release waste products (such as carbon dioxide). Cells may also release or uptake molecules in response to external signals. Describe 3 separate ways that cells may transport molecules across membranes.

Answers

Cells are surrounded by a membrane that serves as a barrier between the environment and the cell's interior. Cells must obtain essential molecules from their environment (such as oxygen and glucose), and release waste products (such as carbon dioxide). Cells may also release or uptake molecules in response to external signals.

The three separate ways that cells may transport molecules across membranes are facilitated diffusion, active transport, and endocytosis. Explanation:

Facilitated diffusion: Facilitated diffusion is a type of passive transport in which specific integral membrane proteins aid the movement of large or charged molecules down their concentration gradients across the cell membrane. Facilitated diffusion helps glucose, amino acids, ions, and other substances cross the plasma membrane through specific transport proteins. These transport proteins are selective and only allow certain molecules to cross the membrane. Facilitated diffusion occurs spontaneously and does not require energy expenditure from the cell.

Active transport: Active transport is a type of transport that requires energy from the cell to move molecules against their concentration gradient. The energy required for active transport is supplied by ATP, a molecule produced by the cell during cellular respiration. This energy is used to move molecules such as ions, amino acids, and glucose from areas of low concentration to areas of high concentration. Active transport occurs through carrier proteins or pumps. Carrier proteins are proteins that bind to the molecule being transported and then undergo a conformational change that moves the molecule across the membrane. Pumps are proteins that use ATP to move molecules against their concentration gradients.

Endocytosis: Endocytosis is a type of transport in which the cell membrane invaginates and forms a vesicle around the molecule being transported. The vesicle then detaches from the membrane and moves into the cell's interior. Endocytosis is used to transport large molecules, such as proteins and polysaccharides, into the cell. There are three types of endocytosis: phagocytosis, pinocytosis, and receptor-mediated endocytosis. Phagocytosis is the process by which the cell engulfs solid particles such as bacteria, while pinocytosis is the process by which the cell takes up fluids. Receptor-mediated endocytosis is the process by which the cell takes up specific molecules that have bound to receptors on the cell membrane.

In the 1940s and 1950s, Dr Barbara McClintock studied mosaic colour patterns in corn and discovered their unstable inheritance and the underlying mechanisms. In 1983 she was awarded the Nobel Prize in Physiology/Medicine for her discovery, and is now considered one of the most influential geneticists of the 20th century. (a) Name two synonymous names for the genetic elements that Dr McClintock discovered
(b) What can these genetic elements do, and what can the consequences be for a gene and for a host genome?
(c) Which gene function do these elements require for their activity, and what are the two classes that these elements can be assigned to, and how do these two classes function in a host genome? (d) Why did Dr McClintock initially find resistance to publish her findings and in the scientific community, to the point that she did not publish these for 20 years, and why were her ground-breaking research findings a paradigm shift in the end?

Answers

They are known by two synonymous names: transposable elements or transposons. These elements can move within a genome and have various consequences for a gene and the host genome.

(a) The two synonymous names for the genetic elements discovered by Dr. McClintock are transposable elements and transposons. These terms refer to segments of DNA that have the ability to move or transpose within a genome.

(b) Transposable elements can have various effects on genes and the host genome. They can insert themselves into a gene, disrupting its function and causing mutations. They can also influence gene expression by inserting near regulatory regions, affecting the level of gene activity. Additionally, transposable elements can cause genomic rearrangements, such as duplications, deletions, or inversions, altering the structure of the genome.

(c) The activity of transposable elements requires specific genes called transposase genes. Transposase enzymes catalyze the movement of transposable elements within the genome. Transposable elements can be classified into two main classes: Class I retrotransposons and Class II DNA transposons. Class I retrotransposons transpose via a copy-and-paste mechanism, where the element is first transcribed into RNA, then reverse transcribed back into DNA and inserted at a new location. Class II DNA transposons, on the other hand, move through a cut-and-paste mechanism, directly excising from one genomic location and reinserting into another.

(d) Dr. McClintock initially faced resistance and skepticism from the scientific community, which led her to withhold publishing her findings for nearly 20 years. At the time, the prevailing belief was that genes were fixed entities with stable positions in the genome. Dr. McClintock's discovery of mobile genetic elements challenged this view and was initially met with skepticism.

Organs are composed of single cell types that have differentiated to perform a specific bodily function.
a. true
b. false

Answers

Organs are composed of single cell types that have differentiated to perform a specific bodily function. This statement is false.

Organs are complex structures that are typically composed of multiple cell types working together to carry out specific functions. These different cell types within an organ often have distinct roles and specialized features that contribute to the overall function of the organ. For example, the heart is an organ composed of various cell types, including cardiac muscle cells, connective tissue cells, and blood vessel cells. Each of these cell types has a unique function and contributes to the overall pumping action of the heart.

The differentiation of cells is a crucial process during development, where cells acquire specialized characteristics to perform specific functions within the body. However, it's important to note that organs are not comprised of a single cell type but rather a combination of different cell types that work in harmony to fulfill their respective roles.

Question 53 - Passage 10
Based on the information in the passage, the mutation that causes the LP phenotype is most likely located in:
A. an intron within the lactase gene.
B. the coding sequence of the lactase gene.
C. an enhancer sequence of the lactase gene.
D. the stop codon at the end of the lactase gene.

Answers

According to the passage, the mutation that causes the LP phenotype is most likely located in an enhancer sequence of the lactase gene.

The passage states that the lactase gene has an enhancer sequence that controls its expression in the intestine. The mutation that causes lactase persistence likely affects this enhancer sequence, allowing lactase to continue to be produced into adulthood. This is supported by studies mentioned in the passage that have identified variations in this enhancer sequence among different populations with varying degrees of lactase persistence. Therefore, option C is the most appropriate answer to this question.


Based on the information provided, the mutation that causes the Lactase Persistence (LP) phenotype is most likely located in an enhancer sequence of the lactase gene (option C). This is because enhancer sequences play a role in regulating gene expression, and the LP phenotype is associated with increased lactase production in adults. A mutation in an enhancer sequence could alter the regulation of the lactase gene, leading to the observed phenotype. Options A, B, and D are less likely as they involve different parts of the gene and may not have the same impact on gene regulation and expression.

Which of the following is not a natural cause of extinction?
a.competition due to overpopulation
b.introduction of non-native species
c.catastrophic events
d.disease​

Answers

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.

HOPE THIS ANSWER HELPED :)

Among the given options, the one that is a natural cause of extinction would be:

b). Introduction of non-native species.

'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.

These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.

Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.

They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.

Hence, option b is the correct answer.

Answers

Let's focus on Phosphorus as the critical scarce resource. Here are the answers to your questions:

Reasons for Criticality and Primary Use of Phosphorus:

a. Essential Nutrient: Phosphorus is an essential nutrient for plant growth. It plays a crucial role in processes like photosynthesis, energy transfer, and DNA synthesis. Without phosphorus, plants cannot develop properly, impacting agricultural productivity.

b. Limited Reserves: Phosphorus reserves are finite and concentrated in a few countries. The scarcity arises from limited availability and geopolitical factors, making it critical for long-term sustainability.

c. Multiple Applications: Phosphorus is primarily used in fertilizers to enhance soil fertility and crop yields. It is also utilized in animal feed additives, detergents, food preservatives, and various industrial applications.

Impact of Decreased Availability on Price, Demand, and Production Costs:

As the availability of phosphorus decreases:

a. Price Increase: The price of phosphorus would likely rise due to supply-demand imbalances. Limited supply in the face of consistent or growing demand would drive up prices.

b. Demand Impact: Higher prices may lead to reduced demand for phosphorus-dependent products, especially in agriculture. Farmers might reduce fertilizer usage or seek alternatives, affecting the demand for phosphorus.

c. Production Costs: Industries relying on phosphorus would experience increased production costs due to higher input costs. This includes agricultural production, leading to potentially higher food prices, and other sectors dependent on phosphorus-based products.

Impact on National Economy:

Decreased availability of phosphorus can impact the national economy in several ways:

a. Agricultural Productivity: A decline in phosphorus availability would hamper agricultural productivity, leading to lower crop yields and potentially affecting food security.

b. Economic Sectors: Industries relying heavily on phosphorus, such as agriculture, food processing, and chemical manufacturing, may face challenges. The increased costs could impact their competitiveness and profitability.

c. International Trade: Countries heavily reliant on phosphorus imports might face trade imbalances and vulnerability in global markets. Dependence on a scarce resource increases the risk of supply disruptions and trade disputes.

Actions for American Companies:

American companies can minimize negative economic impacts by:

a. Resource Efficiency: Implementing technologies and practices that maximize the efficient use of phosphorus, such as precision agriculture and nutrient recycling systems.

b. Diversification of Inputs: Investing in research and development to identify and adopt alternative nutrient sources or develop phosphorus-efficient crop varieties.

c. International Cooperation: Collaborating with international partners to explore sustainable phosphorus management strategies, including recycling and responsible mining practices.

Actions for the Federal Government:

The Federal government can support the economy in the face of declining phosphorus availability by:

a. Research and Development: Investing in R&D initiatives to explore alternatives to phosphorus-based fertilizers, improve phosphorus recovery from waste streams, and promote sustainable agricultural practices.

b. Policy Measures: Implementing policies that incentivize phosphorus recycling, sustainable land management, and efficient fertilizer use. This can be done through regulations, tax incentives, or subsidies.

c. International Engagement: Engaging in global partnerships and collaborations to address phosphorus scarcity collectively, advocating for responsible mining practices, and ensuring fair trade in phosphorus-related products.

These actions aim to reduce dependence on phosphorus, promote resource efficiency, and stimulate innovation to mitigate the economic impacts of its declining availability.

4) golgy apparatus

a) 1,2,3,4
b) 2,4,3,1
c) 1,2,4,3
d) 3,2,4,1

Answers

Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

Describe the structure of large bones.

Answers

Answer:

Periosteum, Compact Bone, Spongy Bone, Bone Marrow, Articular Cartilage, Medullary Cavity

Explanation:

Periosteum: The outermost layer of a bone is called the periosteum. It is a tough, fibrous membrane that covers the bone's surface. The periosteum contains blood vessels, nerves, and connective tissue that nourish and support the bone.

Compact Bone: Beneath the periosteum lies a layer of compact bone, also known as cortical bone. Compact bone is dense and hard. It forms the main shaft or diaphysis of the long bone. Its structure consists of multiple layers of tightly packed mineralized matrix called lamellae, which contain collagen fibers. Compact bone provides strength and protection to the bone.

Spongy Bone: The interior of the bone, particularly at the ends and in the middle of long bones, contains spongy bone, also called cancellous or trabecular bone. Spongy bone has a porous, lattice-like structure composed of thin, branching bony plates called trabeculae. The spaces between the trabeculae are filled with bone marrow. Spongy bone helps reduce the weight of the bone while providing support and flexibility.

Bone Marrow: Within the spaces of spongy bone is bone marrow. There are two types of bone marrow: red marrow and yellow marrow. Red marrow is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Yellow marrow consists mainly of fat cells and serves as a storage site for adipose tissue.

Articular Cartilage: At the ends of long bones, where they articulate with other bones in joints, there is a layer of smooth, slippery cartilage called articular cartilage. It helps reduce friction and absorbs shock during movement, facilitating smooth joint motion.

Medullary Cavity: Within the diaphysis or shaft of the long bone, there is a hollow space called the medullary cavity. The medullary cavity contains bone marrow and serves as a storage site for yellow marrow.
