Answers
The example of carbon being moved from the biosphere to the lithosphere is "Organic materials fall to the ocean bottom and become incorporated into sediment".
What is carbon being moved from the biosphere to the lithosphere?When organic materials, such as dead organisms or their waste products, sink to the ocean floor, they can become buried in sediment. Over time, the pressure and temperature of the sediment can cause it to undergo a process called diagenesis, where it turns into rock.
This process can convert the organic material into fossil fuels, such as coal or oil, which are stored in the lithosphere. Therefore, organic materials falling to the ocean bottom and becoming incorporated into sediment is an example of carbon being moved from the biosphere (living organisms) to the lithosphere (rock layer).

c. fluid enters metanephridia through a funnel-shaped opening.
d. selective reabsorption of materials occurs via cells lining the tubules in protonephridia and via capillaries in metanephridia.
e. the urine produced in both systems is more dilute than the body fluids.
Answers
Metanephridia and protonephridia are two types of excretory systems found in invertebrates. Both systems are responsible for filtering waste materials from the body fluids and expelling them from the body. However, they differ in their structures and mechanisms of filtration and reabsorption. The answer to the question is d.
Metanephridia are more advanced than protonephridia and are found in more complex organisms such as earthworms and mollusks. They are surrounded by an extensive capillary network, allowing for efficient reabsorption of materials. The fluid enters metanephridia through a funnel-shaped opening and is then filtered through a series of tubules lined with cells that selectively reabsorb useful substances. The remaining waste is then expelled through an opening in the body wall.
Protonephridia, on the other hand, are simpler structures found in flatworms and some other invertebrates. The fluid from the body cavity enters protonephridia without first being filtered. The tubules are lined with cells that selectively reabsorb useful substances, and the remaining waste is expelled through an opening in the body wall.
The answer to the question is d. In both systems, selective reabsorption of materials occurs, but in protonephridia, it occurs via cells lining the tubules, whereas in metanephridia, it occurs via capillaries. The urine produced in both systems is more dilute than the body fluids as they eliminate excess water along with waste materials.

Answers
Glucose molecules can produce a total of 20 ATP molecules through fermentation.
This is because, in the absence of oxygen, yeast cells undergo fermentation which involves the breakdown of glucose molecules into pyruvate molecules and the subsequent conversion of pyruvate into ethanol or lactic acid.
During this process, a net gain of 2 ATP molecules is produced from each glucose molecule. Therefore, 10 glucose molecules can produce a total of 20 ATP molecules through fermentation.

describe the trends for world population and water use
Answers
The exact number of people living on Earth in the coming decades is uncertain, but we do know that the population will continue growing, and this will impact water availability. Investing in efforts that slow the rates of population growth through increasing access to voluntary family planning services can help ensure that ample water is available for global food production, ecosystem health, and political and social stability.
Links between Population and Water
Population growth is a major contributor to water scarcity. Growth in populations means mounting demand and competition for water for domestic, industrial, and municipal uses. Water
is also needed for agriculture and industrial use, and for the evacuation of waste materials. The most water scarce or stressed areas are typically those with few water resources,
high population densities, and high population growth rates.3 Population growth limits the amount of water available per person, drives people into marginal regions—which are already water stressed—and also
into cities. For instance, most of the countries in the Middle East and North Africa (MENA) region cannot meet their current water demand. Seven of the world’s 10 water scarce countries are in the MENA region 4. With per capita water availability projected to fall by half by 2050,
the situation is likely to be dire in the coming years.5 Projections show that by 2035, 3.6 billion people will be living in areas with water stress or scarcity, as population growth causes more countries and regions to become water scarce6. The path of future population growth will impact water stress and scarcity .This path will largely depend on the choices that men and women make today about the size of their families, and the family planning services that are available to them as they make these choices.
Agriculture accounts for approximately 70 percent of global water use, and for as much as 95 percent of water use in predominantly agriculture-based countries. Agriculture not only requires a large amount of water, but it is also one of the most inefficient uses of water.8 A growing population requires more food. More water is needed
to produce that food. Agricultural productivity is a crucial component of global food security and, therefore, water scarcity and hunger are closely interrelated. Population growth,
along with development, will double global food demand by 2050. This will require increased agricultural production and put increased pressure on water resources.9

Answers
Based on the given data, the baby bug's genotype is heterozygous, and its phenotype displays the dominant trait.
1. To determine the genotype, we need to know the combination of alleles that the baby bug has inherited from its parents. Since the term "heterozygous" is mentioned, it means the baby bug has inherited different alleles (one dominant and one recessive) from its parents.
2. As the baby bug's genotype is heterozygous, its phenotype will be determined by the dominant allele present in the genotype.
Phenotype refers to the observable physical or biological traits that result from the expression of genes.

The aerobic threshold is the level of physical effort at which a person's cells are just beginning to carry out fermentation to meet some of their energy needs. Marathon runners try to stay at or below the aerobic threshold so that they can go longer distances without experiencing difficulty. While running up and down the hills of San Francisco, the runner was focused on trying to maintain the pace he had when he was running on flat land. What impact did this focus have on his ability to maintain his aerobic threshold?
Answers
The focus will negatively impact the ability of the runner to maintain his aerobic threshold because more effort would be needed when running up the hill.
What is aerobic energy?Aerobic energy is the energy generated as a result of aerobic respiration, respiration that takes place in the presence of oxygen.
Aerobic respiration differs from anaerobic respiration because the latter does not require energy. More amount of energy is generated during aerobic respiration than during anaerobic respiration.
In humans, anaerobic respiration only occurs during highly intense activities when oxygen availability is no longer enough to supply the required energy.
More effort/energy is required to run up a hill than to run on the surface, especially if the same pace is to be maintained on both. Thus, if a runner is focusing on maintaining his aerobic threshold, he should not exert more effort to climb up a hill. Instead, he should reduce the pace of his running.
Otherwise, he will break his aerobic threshold and anaerobic respiration will set in.

Which of the following is NOT true of anaerobic metabolism? a It is relied upon for high-intensity, short-duration activities like sprinting. b It occurs in the cytosol of cells. c Its primary fuel is fat. d It doesn't require oxygen.
Answers
Answer: The option that is NOT true is:
C. Its primary fuel is fat.
Explanation:
Anaerobic metabolism does not primarily rely on fat as its fuel source.
The correct answer is Option (c)
Option (c) Its primary fuel is fat, which is NOT true of anaerobic metabolism.
Let's delve into the topic by breaking down the words anaerobic, which gives us an-aerobic.
Aerobic refers to anything, which involves the presence of air, or more specifically oxygen. Thus any aerobic activity would involve the presence and usage of oxygen for its necessary functions.
Anaerobic would thus mean any activity which doesn't require the presence of oxygen.
Anaerobic metabolism defines the process by which cells, without the presence of oxygen, produce energy for their work. When the supply of oxygen is limited, cells opt for this alternative pathway to produce energy to keep themselves running.
Here, the breakdown of glucose occurs even in limited oxygen to give us ATPs (Adenosine Triphosphate), the energy currency of the cell.
Coming back to the question, we go through the options one by one.
During high-intensity activities like sprinting or heavy exercise, your lungs don't work fast enough to provide the body with enough air. Thus the glucose gets decomposed without the presence of oxygen to give the body the energy it needs through anaerobic respiration.
Thus, option A is correct.
Anaerobic respiration or metabolism occurs in the fluid part of the cell known as the cytosol, due to the availability of a suitable environment for chemical reactions.
Thus option B is correct.
Anaerobic metabolism doesn't require oxygen, as discussed before.
Thus option D is correct.
But, the primary source of fuel for running anaerobic chemical reactions is not fat, but glucose which breaks down to give ATP.
Thus, option C is incorrect.
Thus, the answer to the question is option C.

Answers
Domestication is the term for human intervention in the reproduction of another species that results in certain plants and animals being more dependent on humans and helpful to them. Here option A is the correct answer.
Domestication refers to the process by which humans selectively breed plants and animals for desirable traits, such as increased yield or docility, and thereby create populations that are dependent on humans for their survival and reproduction. Domesticated species differ from their wild ancestors in various ways, including morphology, behavior, and genetics.
Domestication has been a crucial factor in the development of human societies, as it has allowed humans to secure a reliable source of food, fiber, and labor. Domesticated plants and animals have been selectively bred and managed by humans for thousands of years, leading to the development of new and improved crop varieties and livestock breeds.
However, domestication also has its drawbacks. Domesticated populations can be vulnerable to disease, predation, and environmental changes, and they often require intensive management to thrive.

The variation of genes within a species.
The variation between the males and females of a species.
The variation of ways in which genetic information is passed to offspring.
Answers
Answer:
So it would be the first one, The variation in biological factors affecting a species.
Explanation:
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species.
All forms of life on earth, whether microbes, plants, animals, or human beings, contain genes. Genetic diversity is the sum of genetic information contained in the genes of individual plants, animals, and micro-organisms. Each species is the storehouse of an immense amount of genetic information in the form of traits, characteristics, etc. The number of genes ranges from about 1000 in bacteria to more than 400 000 in many flowering plants. Each species consists of many organisms and virtually no two members of the same species are genetically identical.
An important conservation consequence of this is that even if an endangered species is saved from extinction it has probably lost some of its internal diversity. Consequently, when populations expand again, they become more genetically uniform than their ancestors. There are mathematical formulas to express a genetically effective population size that explain the genetic effects on populations that have gone through a bottleneck before expanding again such as the African cheetah or the North American bison. Subsequent inbreeding in small populations may result in:
a) reduced fertility and
b) increased susceptibility to disease.
Genetic differentiation within species occurs as a result of sexual reproduction, in which genetic differences between individuals are combined in their offspring to produce new combinations of genes or from mutations causing changes in the DNA. Genetic diversity is usually mentioned with reference to agriculture and maintaining food security. This is because genetic erosion of several crops has already occurred leading to the world's dependence for food on just a few species. Currently, a mere 100-odd species account for 90% of the supply of food crops, and three crops – rice, maize, and wheat – account for 69% of the calories and 56% of the proteins that people derive from plants.

explain how the genetic information that is stored in DNA becomes a protein that can be used by the cell?
Answers
Answer:
First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins.
In transcription, the information in the DNA of every cell is converted into small, portable RNA messages. During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are 'read' to make specific proteins.
Have a wonderful day! :-)
Answer:
Explanation:
The process of converting genetic information stored in DNA into functional proteins that can be used by cells is known as gene expression. This process is composed of several steps:
Transcription: The first step in gene expression is the transfer of genetic information from DNA to RNA. This is accomplished through the process of transcription, where an enzyme called RNA polymerase reads the DNA code and synthesizes a complementary RNA molecule. This RNA molecule is called messenger RNA (mRNA).
Splicing: Before the mRNA molecule is transported out of the nucleus, it may undergo a process called splicing. This process involves the removal of non-coding sequences of the mRNA molecule, leaving only the coding sequence, called exons.
Translation: After the mRNA molecule has been processed and is in the cytoplasm, it is translated into a protein by ribosomes. The ribosome reads the sequence of codons (groups of three nucleotides) in the mRNA molecule and uses this information to assemble a chain of amino acids. The amino acids are linked together through peptide bonds to form a functional protein.
Post-translational modification: Once the protein is produced, it may undergo further modification, such as folding into its final 3D shape or modification by the addition of chemical groups. These modifications are important for the proper functioning of the protein.
In summary, gene expression is the process by which the genetic information stored in DNA is transcribed into mRNA, processed, and then translated into functional proteins in the cytoplasm. These proteins carry out the functions that are essential for the survival and functioning of cells.
