Question

Q1.
Why do capillaries in a human body do not have any valves?
Q2.
Name some fruits which do not have seeds. How do they propagate?
03 What would eventually happen to species if the organisms lose the ability to
reproduce.
​

Answer 1

Answer:

Here's your answer,

Explanation:

1. 1. From the arteries, the entry of blood occurs in the capillaries which happens by the pressure of blood. Then it enters the veins. From here, the blood enters to the heart's right side. It is clear that the blood travels because of pressure of blood so there is no requirement of valves in the capillaries.
2. Common varieties of seedless fruits include watermelons, tomatoes, grapes (such as Termarina rossa), and bananas. ... Lacking seeds, and thus the capacity to propagate via the fruit, the plants are generally propagated vegetatively from cuttings, by grafting, or in the case of bananas, from "pups" (offsets).
3. Unless humans intervene to clone it, it will become extinct. How long this takes will depend on the nature of the organism - it could take anything from a few hours to thousands of years.

Answer 2

Answer:

1. This is because in capillaries there is no chance of blood flow back.

so no valves are present.

2. Common varieties of seedless fruits include watermelons, tomatoes, grapes (such as Termarina rossa), and bananas.Lacking seeds, and thus the capacity to propagate via the fruit, the plants are generally propagated vegetatively from cuttings, by grafting, or in the case of bananas, from "pups" (offsets).

3. Reproduction is nature's method of ensuring that a species does not become extinct. Hence if every member were to suddenly lose the ability to reproduce that species would soon become extinct or no longer exist.
