Connect the importance between meiosis and the process of sexual reproduction. Is it possible to survive without your reproducti
Aleksandr [31]
It must be known that there is an interdependent relationship between meiosis and sexual reproduction. During sexual reproduction, meiosis generates a genetic variation in the offspring because it randomly shuffles genes across chromosomes and then randomly segregates half of those chromosomes into each gametes. These two gametes or sex cells then fuse randomly to form a new organism. One of the key factors in evolutionary fitness and biological diversity is genetic variation. This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation.

To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.

Reproductive organs of both men and women are vital to create a child. But it must be noted that both can live without them. There are situations that sometimes necessitates the removal of such organs especially if he or she is inflicted with cancer or other diseases.

3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
Marianna [84]

Answer:

See the answer below

Explanation:

First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:

6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2

The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy

<u>The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.</u>

<em>In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.</em>
