Explanation:
Classification of Living Things Notes
1. An organism is a living thing.
2. Characteristics of all living things:
1) Organisms obtain and use resources. All organisms must obtain resources, such as food and water, which provide required energy to perform the basic processes of life, like growing, developing, and repairing injured parts.
2) Organisms respond to stimuli: A stimulus is any change in an organism’s surroundings that will cause the organism to react. Examples of environmental stimuli include changes in the amount of light present, changes in temperature, sound, amount of water, space, amounts of food present. The reaction to the stimulus is called a response. It can be an action or behavior performed by the organism.
3) Organisms reproduce-produce offspring that have similar characteristics as the parents. Reproduction can occur in one of two ways:
a) Asexual reproduction involves one parent that makes an exact copy of itself. The offspring are identical to the parent.
b) Sexual reproduction involves two parents. Sperm cell from the male and egg cell from the female combine to produce offspring that have characteristics from each parent.
4) Organisms grow and develop. Growth is the process of an organism becoming larger. Development is the process that occurs during the life of an organism that results in the organism becoming more complex. Organisms require energy to grow and develop.
3. Classification is the process that scientist use to arrange organisms into groups based on the shared observable characteristics.
4. Taxonomy is the science of identifying and classifying organisms into groups.
5. A taxonomist is a scientist who identifies and names organisms based on their similarities and differences.
6. Taxonomist use physical characteristics as well as DNA, genetic information, to classify organisms.
7. Scientist all over the world study organisms, in order to avoid confusion scientists need a universal way of naming organisms.
8. A dichotomous key is a tool used to identify organisms. It uses a series of questions, each with only 2 answers.
9. Linnaeus developed a system for classifying organisms called binomial nomenclature. It uses two Latin words to name an organism. The name is made up of the genus and species of the organism. The name is written in italics, the genus is capitalized, and the species is lower case; for example, the scientific name for a human is Homo sapiens.
10. The Linnaeus system is made up of seven levels, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
1) King Philip Could Only Find Green Socks is one mnemonic way to remember the order of the levels. Another is King Philip Came Over For Good Spaghetti.
2) The levels are arranged from the most broad, Kingdom, to the most specific, Species.
11. Kingdom- organisms are placed into kingdoms based on their ability to make food and the number of cells in their body.
12. Phylum (phyla is plural)- In the Plant Kingdom, phyla are sometimes called divisions. In the Animal Kingdom, there are 35 different phyla.
13. Class, Order, Family-these levels become even more specific. Each level has fewer organisms that have more in common with each other as you move down the levels.
14. Genus- contains closely related organisms. The genus is the first word in an organism’s scientific name.
15. Species- consists of all the organisms of the same type which are able to breed and produce young of the same kind. The species is the second word in an organism’s scientific name.
16. Most scientists classify organisms into 5 kingdoms: Plants, Animals, Protists, Fungi, and Monera.
1) Plants (Plantae)- the plant kingdom is made up of plants. Plants are autotrophs, they make their own food. Plants are eukaryotes; they are made up of many cells. Plants are divided into 2 groups: vascular and nonvascular.
2) Animals (Animalia)- the animal kingdom is made up of animals. Animals are heterotrophs- they must obtain food by eating it. Animals are eukaryotes. The 35 phyla are divided into two groups: vertebrates and invertebrates.
3) Fungi- the fungi kingdom is made up of molds, yeasts, and mushrooms. Fungi are heterotrophs because they must absorb their food. Yeasts are one celled, while molds and yeasts are eukaryotes. Their cells have a nucleus, a cell wall, and no chlorophyll. Most fungi are decomposers, they break down dead organisms.
4) Protists (Protista)- the protists are made up of organisms that cannot easily fit into the plant, animal, or fungi kingdoms. They are one celled organisms with a nucleus or simple multicelled organisms. Some protists are autotrophs, some are heterotrophs.
5) Monera- the Monera kingdom is made up of bacteria. Their cells do not contain a nucleus. Some bacteria are autotrophs, some are heterotrophs.

Answers
Answer:
Sympathetic nervous system makes the body ready to fight or fight response during any danger in the body.
While
Parasympathetic nervous system slow the body from performing too much work there by restoring the body to calm and composed state
Explanation:
The autonomic nervous system is divided into two; the sympathetic and parasympathetic nervous system. The autonomic nervous system controls the involuntary actions of internal organs and glands.
The sympathetic nervous system originate from the spinal cord and and it's is responsible for accelerateing the heart rate, constricting blood vessels, and raising blood pressure. Thereby preparing the body to fight or fight response against any danger.
The parasympathetic nervous is a part of autonomic nervous system that also originate from the spinal cord which which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. By doing this,it prevent the body from overworking itself and restore the body to a calm and composed state.

We conclude that the cats are not detectably inbred when studying about the population of an endangered wildcat in India.
Signs of immoderate inbreeding encompass ordinary small clutter sizes (one or kittens), crooked noses, misaligned jaws, extraordinary eye set and asymmetry. Male and ladies might also additionally revel in low fertility and most cancers is greater not unusualplace in more youthful cats.
Inbreeding is the mating collectively of intently associated cats, as an instance mother/son, father/daughter, sibling/sibling matings and half-sibling/half-sibling. It is the pairing of animals which might be greater intently associated than the common population.
In the wild, there'll constantly be a few diploma of inbreeding when you consider that cats will obviously breed with their near loved ones if they arrive into touch with every different while the girl is in heat. Therefore, a few diploma of inbreeding is natural.

A change in dna has caused snail p to be very different from the other five snails
suggest why there might be an increasing number of snails similar to snail p in each future generation
Answers
The change in DNA of snail P may have led to a beneficial trait that provides an advantage in survival and reproduction, resulting in an increasing number of snails with similar characteristics in each future generation.
A change in DNA can occur due to a mutation or a genetic variation that alters the genetic makeup of an organism. In the case of snail P, this change in DNA has caused it to be very different from the other five snails. This difference can lead to a distinct phenotype that may provide some advantages to the snail, such as better adaptation to the environment or resistance to predators.
The presence of this advantageous trait can increase the likelihood of snail P surviving and reproducing, leading to an increasing number of snails similar to snail P in each future generation. This is because the advantageous trait will be passed down to its offspring and may become more common in the population over time through natural selection.
Additionally, if the snail P is able to mate with other snails with a similar genetic makeup, it can further increase the prevalence of the advantageous trait in the population. This phenomenon is called genetic drift, where a particular trait becomes more common in a population due to chance events.
In conclusion, the change in DNA of snail P may have led to a beneficial trait that provides an advantage in survival and reproduction, resulting in an increasing number of snails with similar characteristics in each future generation.

Microvilli are most likely to be found in which type of tissue?
a) simple squamous epithelium
b) simple columnar epithelium
c) adipose
d) stratified squamous epithelium
Answers
Microvilli are most likely to be found in simple columnar epithelium. (B)
Simple columnar epithelium is a type of tissue that lines the inner surfaces of many organs and structures in the body, such as the stomach, intestines, and gallbladder.
This type of tissue is characterized by its tall, narrow cells that are tightly packed together, forming a single layer of cells.
Microvilli are small, finger-like projections that extend from the surface of certain cells, increasing their surface area for absorption and secretion.
Simple columnar epithelium is specialized for absorption and secretion, and the presence of microvilli in this tissue greatly increases its surface area, allowing for more efficient nutrient and waste exchange.
While other types of tissue, such as stratified squamous epithelium, may also contain microvilli in certain areas, simple columnar epithelium is the tissue type most commonly associated with microvilli due to its specialized function in absorption and secretion.

negative nitrogen balance occurs in question 27 options: growing children. lactating women. pregnant women. surgery patients.
Answers
Negative nitrogen balance occurs in surgery patients. This is the correct option.
Negative nitrogen balance means that the body is losing more nitrogen than it is taking in. Nitrogen is an essential component of proteins, and its balance is an indicator of the body's protein status.
Surgery patients may experience negative nitrogen balance due to various reasons such as stress response, inflammation, and metabolic changes, which can lead to an increase in protein breakdown and decreased protein synthesis.
The negative nitrogen balance can lead to the breakdown of muscle tissue, which can result in weakness and delayed wound healing.
To avoid negative nitrogen balance, surgery patients may be prescribed a high-protein diet or given nutritional supplements to promote protein synthesis and muscle growth.
In contrast, growing children, lactating women, and pregnant women are typically in a positive nitrogen balance state, meaning that they are taking in more nitrogen than they are losing. This is because they require additional protein for growth, tissue repair, and milk production.

B Fossil fuels are nonrenewable and may cause pollution.
C Fossil fuels are relatively cheap to produce and easy to use.
D The use of fossil fuels depletes our forests of resources.
Answers
Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for __________.
Answers
the repolarization of the cell.
Mechanism :
Action potentials are signals that are sent and received by muscle and nerve cells. Because of the negative concentration gradient in the resting membrane potential of nerve cells, there are more positively charged ions outside the cell than inside. There are more sodium ions outside the cell and more potassium ions within because these positively charged ions are sodium ions. Action potentials cause the membrane to depolarize, which is followed by the process of repolarizing the cell. The membrane potential changes and reverts to the negative value of the resting potential during repolarization. The potassium channels open and the sodium channels close at this stage, allowing the nerve cell to lose positively charged ions.
