Energy for the cell’s use is stored when
ADP and P form ATP
Acetic acid is formed
Glucose is broken into pyruvic acid
CO2 is released from the reaction
AnswerA. ADP and P form ATP
Explanation:
Hope this is correct!
Answer:
ADP and P form ATP
Explanation:
The high energy is released in steps and picked up by ADP and P to form the high energy phosphate (ATP). For each two hydrogens passed down the chain, three ATPs are produced. At this stage, 36 ATPs are produced from the original glucose that started out in glycolysis. After the hydrogens have given up all of the excess energy they are combined with oxygen to form water. mark me brainy plz! (^_^)

a fifth grade friend has seen a picture of your "child" and asks you to explain how kids get their traits from their parents . using this activity as an illustration, write your explanation for this friend
Answer:
Genes are the basic unit of heredity. This means that genes determine what traits are passed down from a mother and father to their child. Eye color, height, and hair color are some examples of the traits that are controlled by genes. Genes exist inside the cells that make up living things.
Explanation:
Kids get their traits from their parents by getting an allele of each trait from each parent.
How are traits inherited?Each trait is represented by a gene and each gene is represented by two alleles.
The two alleles for each gene are donated by each of the two parents in a union.
For example, let us say the eye color gene is represented by the allele A (a).
One parent is AA while the other is aa.
A child will inherit eye color by getting one A allele from one parent and the other allele (a) from the other parent. Thus, the child will be Aa.

why it is that we inherit mitochondrial DNA ONLY from our mothers?
Answer:
In se*ual reproduction, mitochondria are normally inherited exclusively from the mother; the mitochondria in mammalian sperm are usually destroyed by the egg cell after fertilization. ... The fact that mitochondrial DNA is maternally inherited enables genealogical researchers to trace maternal lineage far back in time.
PLZ HELP ASAP!! Environmental factors can influence the gene expression in some organisms.
Describe how environmental factors can affect an organism’s phenotype.
Explain how light exposure can affect gene expression in organisms of the same species. Provide an example.
plz dont steal points
Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.
Explanation:
True or False: A child may look more like one parent than the other because a child inherits chromosomes from one parent.
Answer:
True
Explanation:
The mitochondria of a cell is the site for which two cellular processes?
Answer:Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Explanation:
Krebs cycle and electron transport chain
Answer:
The Krebs cycle and electron transport chain
Explanation:
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

1) Why did 40% of the human population evolve to tolerate lactose?(1 point)
A Lactose tolerance allows people to enjoy a wide variety of food, including milk, butter, ice cream, and cheese.
B People who have an intolerance experience physical pain, so a tolerance evolved to avoid that.
C Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
D Babies rely on milk to survive, so they need to be able to tolerate lactose.
2) What is the difference between genetic drift and natural selection?(1 point)
A Genetic drift is the change in a population’s genes over time; natural selection is the evolution of a population over time.
B Genetic drift is the frequency of genes in a population; natural selection is the frequency of adaptations in a population.
C Genetic drift is the random increase or decrease of certain genes in a population; natural selection is not random.
D Genetic drift is the selection of random traits in a population; natural selection is the selection of specific traits.
3 What is an interferon?(1 point)
A An interferon is used by a virus to stop the body from detecting it.
B An interferon disrupts DNA replication.
C An interferon reduces the efficacy of antibiotics on bacteria.
D An interferon activates the body’s immune system response to a virus.
4 Why is there such a wide variety of immune system responses between hosts when they are infected with the same virus?(1 point)
A Slight variations due to mutations in the virus trigger different responses in people.
B People that have already been infected are asymptomatic.
C Some viruses are resistant to antibiotics, so they cause a stronger immune system response.
D Each person’s immune system employs different tactics to get rid of the virus.
5 Is the following statement true? “Antigenic drift and other mutations to the DNA of viruses are always beneficial for the virus.”(1 point)
A Yes, because mutated viruses are able to infect more hosts.
B Yes, because mutated viruses have less mRNA so they can copy and replicate faster.
C No, because mutated viruses are may be less likely to replicate.
D No, because different mutations cause a variety of immune responses.
Answer:
1. D- Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
2. B- Genetic drift is the random increase or decrease of certain genes in a population; natural selection is not random.
3. A- An interferon activates the body's immune system response to a virus.
4. D- Each persons immune system employs different tactics to get rid of the virus.
5. D- yes, because mutated viruses are able to infect more hosts.

Define:1. Genetic Drift2. Natural Selection Genetic Drift:Genetic drift is a means of evolution. It refers to random changes in the commonnesses of alleles from generation to generation due to chance events.
Genetic drift can cause features to be dominant population. The effects of genetic drift are most pronounced in small populations.
Natural SelectionNatural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.

Why does a substance like caffeine not bioaccumulate but heavy metals like mercury and lead do? Explain where these toxins are stored in the human body. Hint: is caffeine fat-soluble?
Answer:
Brain, heart, lungs, liver, kidney
Explanation:
Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.
Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.
These toxins are stored in the human brain, heart, lungs, liver, and kidney.
What are heavy metals and examples?
The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.
Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.
Thus, Heavy metals are atoms that cannot be broken down.
