What are the primary blood vessel types and their functions?

1 answer:

8 0

There are three types of primary blood vessels and these are capillaries, veins, and arteries and the function of capillaries to connect arteries and veins, the function of veins to carry blood back to heart, and function of arteries is to take blood away from heart.

<h3>What is blood vessel?</h3>

A structure whose shape is tubular that contain blood through the tissues as well as organs and these are of three types, the capillaries which is known as smallest blood vessel and the function in to connect vein and arteries. The second type of blood vessel is veins that carry blood back to heart. The third type is artery that carry blood away from the heart.

The blood vessel may contain either pure or impure blood and it plays a vital role in the proper functioning of body.

Therefore, there are three types of primary blood vessels and these are capillaries, veins, and arteries and the function of capillaries to connect arteries and veins, the function of veins to carry blood back to heart, and function of arteries is to take blood away from heart.

Answer:

Complex organisms evolved from more simple organisms

Explanation:

<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>

<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>

The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.

What would the results of this experiment look like if the pigments that drive photosynthesis in the algae were to absorb most s

Debora [2.8K]

Attached is the experiment details. I found the exercise on the internet.

The pigments of the algae, according to the experiment, absorb the most strongly around the violet-blue and red parts of the spectrum and so photosynthesis is the most efficient when the algae are under such wave lengths. The results were that more oxygen-seeking bacteria gathered around the algae that were under such wave length because there were more production of oxygen.
If the pigments were now to absorb most strongly around the 500 nm to 560 nm, the bacteria would gather the most around the algae under such wavelegth (green light).

Does cell respiration occur in the plastids ?

RSB [31]

Answer:

Yes it does,

Explanation:

Cellular respiration occurs in both plant and animals. It is the process by which cells convert ADP (adenosine diphoosphate) into ATP (adenosine triphosphate). Plant and animal cells cannot use ADP as a form of energy.
