an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.
Explanation:
Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.For more information:

Analyses of the protein ______ can be used to study evolutionary relationships among species because most organisms produce this protein for the electron transport chain in mitochondria.
Evolutionary relationships among species can be studied when similar structures or materials eg the wings of a bat and the arm of a bird or similar proteins between two different species. This proves to show relationship among organisms.
Analyses of the protein Cytochrome C can be used to study this types of evolutionary relationships.
Cytochrome C is an antioxidative enzyme that is a part of the electron transport chain in mitochondria. Mitochondrion is an organelle that majority of living organisms share in common. This protein is therefore found present in almost all organism carrying out cell respiration. Therefore this protein can be used to analyze and study evolutionary relationship among organisms with this protein.Learn more: https://brainly.com/question/22173470

A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.
Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.
WHAT IS ACTIVE TRANSPORT?Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.
This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?
The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.
First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.
In this case, when a flatworm is cut in half, we can see the following events happen:
At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

I think its B? Can someone explain it to me tho
Explanation:
I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This
will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to
as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.
This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the
complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.
Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain
temperature, although rate of collision will keep on increasing.

Why do the alveoli fill with fluid.
Answer:
Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.
Explanation:
Answer:
The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

Explain how the rate of cooling magma affects the size of
the crystal that form.
Answer: When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

This layered structure can be compared to that of a boiled egg. The crust, the outermost layer, is rigid and very thin compared with the other two. ... The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.
in turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, what is the probability of an individual offspring having yellow feather?
50%
0
25%
100%
Answer:
50%
Explanation:
trust me because the heterozygous is so weird but I know this.
In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
What will be produced in turkeys a dominant gene?In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.
Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.
Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.
Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
