At high altitudes, air is less dense than at sea level because of decreased air pressure. This means that a person who ascends to high altitudes takes in fewer oxygen molecules per breath. Describe and explain an immediate response that occurs in the circulatory system when a person first reaches high altitudes. Use vocabulary from class.

Answers

Answer 1

An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

What are the main effects of altitude?

The higher it is, the worse the symptoms, which include

headacheshortness of breathrapid heartbeatamong others

Not everyone has these symptoms when they go to high-altitude places, but it is also not possible to know who will or will not feel something.

With this information, we can conclude that An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

Two insect groups vary genetically by two genes. When put together, they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
The insects experienced geographic isolation.
The insects experienced reproductive isolation.
The insects are different species.
The insects are the same species.

Answers

Answer:

The insects are the same species.

Explanation:

The insects are the same species because they interbreed with each other successfully. If the organisms belongs to the same species, they have the ability to interbreed with each other and produce fertile offspring while on the other hand, different species can't interbreed with one another. These two organisms have some genetic variations among each other due to environmental factors that leads to the differences between these two organisms.

The insects are the same species because they were able to reproduce and produce offspring that could also breed.

What are species?

Species are a group of related organisms which are able to interbreed and produce reproductively viable offspring.

The species level of taxonomy is the closest relationship and has the fewest number of organisms.

Since, the two insect groups were able to reproduce and produce offspring that could also breed, they are of the same species.
