Answer:

No

Explanation:

No skin color is perfect in ANY environment. One of the uses of melanin (A primary skin pigment) is to absorb ultraviolet rays from the sun that initiate Vit. D production.

So an abundance of melanin is beneficial in an an environment with a large amount of sun to prevent an excess of Vit. D in the blood.

Inversely, less melanin is useful to an individual in an environment that gets little sun since there is not as much melanin to inhibit Vit. D production, and thus is less likely to have a Vit. D deficiency.

The receptors that monitor tension or stretch in muscles are called muscle spindles.

Muscle spindles are receptors that monitor tension or stretch within the body of a skeletal muscle.

They act by mainly detecting changes in the length of the muscle and convey this information to the brain through afferent neurons for processing.

Muscle spindles consist of peripheral endings of nerve fibers that wrap around collagen bundles in the tissue that connects muscle to bone.

I think genetic evidence is more effective because you never know if something crashed into the rock and made it look like a fossil. So, I think genetic evidence would be a better option.

Hope this helps!

Answer:

Both are equal because you can use fossil evidence to show what type of animals evolved but you can also use genetic evidence to show that evolution happened.

Hope this helps! This is just my opinion on the subject.

Answer:

A. Polar

Explanation:

It is covalent but more specifically polar bond

Not ionic since it's covalent

not metallic since there are not metals

Hydrogen bonding is bond between hydrogens and not with others (the bonding between other water molecules can be considered hydrogen bonding)

Answer:

Explanation:

Usually, the sound waves your vocal cords produce travel through air in your voice box. But when they go through the helium that you've inhaled, they travel about three times faster. That's because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out.

Answer:

the sky is blue because of the atmosphere and helium does that because it changes the air in our vocal tract and consequently, the speed of sound waves of our voice increases resulting in a squeaky and funny tone.

Explanation:The adaptations are in place to provide the animal with a better chance of survival. In the desert adaptations are required for plants and animals to survive the hot and dry conditions. Plants have adapted to cope with the lack of water in their environment, for example the barrel cactus has expandable stems for storing water.

Animals in the desert will adapt by the following methods:

Adaptations are special features and structures possessed by organisms which enhances their chances of survival in their environment.

The desert is a hot and dry environment.

Therefore the adaptations will be to reduce heat and conserve water.

In internal respiration ,oxygen is carried by arteries into the cells and waste carbon dioxide moves out into the veins.

Internal respiration is the process by which oxygen move from the blood to the interstitial fluid and into the cells where by Waste and carbon dioxide are removed from the other direction, from the cells to the blood.

Therefore, In internal respiration ,oxygen is carried by arteries into the cells and waste carbon dioxide moves out into the veins because arteries carries oxygenated blood while veins carries deoxygenated blood.

Wow, that's such a cool prokaryotic cell. It looks so delicious, I wonder if I can eat it.

"Hey, cell, can I eat you?"

"No, you cannot."

"Please? I would love to have your energy-making properties!"

"How would I benefit from this? It seems like you're being parasitic."

"I would help you, by giving you protection and a safe home. You would give me energy. It seems more like an endosymbiotic relationship to me!"

"Fine, you can ingest me."

I'm so glad they let me eat them, they were so yummy. I can even create energy now, and I have a powerhouse inside me! This is so cool, maybe I should eat that other cell with photosynthetic properties.

SORRY IF THIS IS TERRIBLE I REALLY TRIED  

Previously, there was a cell. Moving about the primordial soup, it was making its way through the tough environment. It abruptly came across a little prokaryotic cell.

The cell was glad to have someone to share the environment with since, to be completely honest, it was starting to feel a little lonely. The two cells began to interact often and peacefully cohabit.

The first cell began to consider how much simpler it would be to survive if the other, smaller cell moved in with me. After a brief moment of hesitation, the cell fearlessly said, The rest, as they say, is (endosymbiotic) history.

Studies on the mitochondria and chloroplasts are thought to have come from bacteria living in large cells.

Therefore, this supports the theory that eukaryotic cells developed through endosymbiotic relationships between prokaryotes.

Natural selection in the tropical ecosystem favors ferns that are tolerant to shade, high wind velocity, frost, drought, etc.

An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.

The tropical ecosystem consists of dry seasons driven by the tropical rain belt moving within the region. Tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity.

Therefore, Natural selection in the tropical ecosystem favors ferns that are tolerant to shade, high wind velocity, frost, drought, etc.

C. Density-independent

Explanation:

Limiting factors caused by natural disasters that tend to be Density-dependent. Thus, the correct option for this question is B.

The Limiting factors may be defined as anything that significantly constrains a population's size and declines or stops it from growing. Some examples of limiting factors may include biotic, like food, mates, and competition with other organisms for resources.

According to the context of this question, density-dependent factors are those factors that vary with respect to the density of the population. These factors affect a higher proportion of individuals when population densities are higher.

And a lower proportion when population density is lower. Examples of these factors may include, food, competition, predation, competition, parasitism, accumulation of toxic waste, etc.

Therefore, limiting factors caused by natural disasters tend to be Density-dependent. Thus, the correct option for this question is B.
