Why do organisms with one color produce few offspring than those with multiple colors?
Answers
Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

The test: To understand if the ACTN3 protein affects running ability, researchers conducted a test. They recruited a group of competitive runners and measured the level of ACTN3 protein molecules each runner had in their bodies. Then, they had the runners participate in a sprint (a short-distance run). During the test, the runners sprinted as fast as they could for 100 meters.
Evidence: Scientists found that the runners who sprinted the fastest had the highest amount of ACTN3 protein molecules in their bodies.
Do you think that this evidence shows that the ACTN3 protein determines running ability? Explain your ideas using the words protein, trait, and feature in your response.
Answers
Answer:
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. ... Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.

Answers
Answer:
The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function. Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming.

1. Describe the flow of energy to killer whales.
2. If killer whales were removed from the ecosystem, how would it
impact the other organisms?
3. What would you expect to happen if the algae population
increased?
4. Describe how the fish population would change if the seal
population decreased.
Answers
If those whales were to be removed from the echo system then the population of other species would increase and be too much.
If the algae increased then animals like fish would start to increase
The fish population would grow to be huge and fish would be common
The killer whales have a tremendous flow of energy as the whale eats and consume more protein and a nutrient-rich diet.
What is a killer whale?1. A killer whale is also called an Orca and a toothed whale. The whale is the largest member of the killer whale specie and has tremendous flow of energy due to they fed on small and large aquatic forms.
2. If the whale is removed from the ecosystem then the food chain will get disturbed and there will large growth of other species of fish will be in abundance.
3. If the algae increase the oxygen in the lakes and seas will be depleted and other species will be impacted as the fish popuaion may get reduced.
4. if there a change in seal popualtion then popualtion of fish will double itself and again distub the food web.
