Discuss the similarities and differences between whale flippers and flukes and fish fins, using the scientific terms "homologous structures" and "analogous structures" in the discussion.
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.

Label the angle of incidence and the angle of reflection in the Figure below.
In the picture, I have highlighted the angle of incidence blue and the angle of reflection red.
hope this helps :)
Angle of incidence refers to the angle between the incident ray and the normal, while angle of reflection represents the angle between the reflected ray and the normal.
Thus, angle of incidence is the angle formed by the incident ray which is the light beam flowing in and the normal which is a line perpendicular to the surface at the point of incidence. The angle of reflection, denoted by the symbol r, is the angle between the normal and the reflected ray of light (the ray of light that bounces off the surface).
The angle of incidence and angle of reflection are equal, according to the law of reflection. The angle at which light reaches a surface and the angle at which it reflects off of it are identical. This fundamental concept describes how light interacts with surfaces, such as mirrors or smooth objects.

Michelle and Juan are working on a science project. They take a large glass jar, fill it with some damp paper towels, and then with seeds. They place this jar near a window. After a few days, they see that the seeds germinate and produce stems growing upward. Next, they moisten the towels again and lay down the jar on its side. What are they most likely to observe about the stems after turning the jar on its side?
A: Grow sideways in their new position
B: Start growing downward in their new position
C: Stop growing more than they have already grown
D: Start growing upward in their new position

If the Earth took longer to complete a revolution, how would it affect a Solar day and a Sidereal day?
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.
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.

Answer: I think it's A
Explanation: Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

Answer:Animals in the desert are adapted to the hot climate.
Most live underground to stay cool.
Explanation:
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.
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.

Why do organisms with one color produce few offspring than those with multiple colors?
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.
Explanation:
Why do organisms with one color produce few offspring than those with multiple colors?
Answer:
The answer is literally nature selection.

It just depends on it.

Answer:
Natural resources are not evenly distributed all over the world. Some places are more endowed than others — for instance, some regions have lots of water (and access to the ocean and seas). Others have lots of minerals and forestlands. Others have metallic rocks, wildlife, fossil fuels, and so on.
