What role does vasoconstriction play in thermoregulation​

Answers

Answer 1

Explanation:

In endotherms, warm blood from the body's core typically loses heat to the environment as it passes near the skin. Shrinking the diameter of blood vessels that supply the skin, a process known as vasoconstriction, reduces blood flow and helps retain heat.Thus, the blood returning to the heart has not lost much heat.

Answer 2

Answer:

Reduces blood flow and helps retain heat thus the blood returning to the heart has not lost much heat

are mitosis and meiosis alike and different?
Summarize evidence to support your claim
and explain your reasoning.

Answers

The fundamental difference between mitosis and meiosis is that mitosis produces two daughter cells with the same number of chromosomes as the parent cell. Meiosis results in four daughter cells harboring only half of their parent's chromosomes, which underwent recombination.

How would blood flow be affected if the aorta decreased in diameter?

Answers

Answer:

A decreased diameter means more of the blood contacts the vessel wall, and resistance increases, subsequently decreasing flow. The influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a huge decrease or increase in resistance.

Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil

Answers

Answer:

The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.

Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.

How can polyploidy cause speciation in plants?

Plants can sexually reproduce only when they are polyploid. Having the condition is normal in plants.
Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.
Plants can repair polyploidy and obtain healthy cells. This allows plants to survive and reproduce.
Plants are not affected by polyploidy. Plants with the condition can reproduce normally.

Answers

Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce, this results develop cause speciation in plants, hence option B is correct.

What is polyploidy in plants?

Polyploidy, which occurs when two or more genomes fuse within one nucleus, causes each cell to possess more than two pairs of homologous chromosomes.

Most angiosperms exhibit polyploidy, which is crucial for the survival of the agricultural crops on which people depend.

Three or more sets of homologous chromosomes are present in polyploid plants. These plants' increased chromosome count is the outcome of a genome duplication event.

Therefore, plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.

The two lower chambers of the human heart are known as:
a.
atriums
c.
auricles
b.
ventricles
d.
blood vessels

Answers

Answer:

b. ventricles

The right and left ventricles

Answer:

B(ventricles)

Explanation:

So lets go over the heart.

First blood circulates from your body to your heart. This is through blood vessels. These blood vessels are connected to the inferior and superior vena cava that go into the heart.

So, this means that the blood vessels are outside of the heart, not the lower areas.

Then, the blood goes into the right artierium, and down to the right venticle. So, thinking about this, it means that the artieriums are the top chambers.

The word auricles is another word for artiums, which we already know are the top chambers.

The venicles are below this, these must be the bottom chambers.

I attached files of some notes I took on the heart, they show the strucutre of the heart and the workings of the heart and circulatory system.

Hope my answer or notes helps! ;)
