Explain why genetic diversity is necessary in order for natural selection to occur

Answers

Answer 1

Answer:

It is significant because, this is where the stronger and more affinated genes are conceived, thus survive.

Genetiic variation is simply the different variety of genetic make up and what is called alleles. Alleles are similar to a code for the body which determines such things as hair color, eye color, height, and other factors.

Genetic variation is therefore the variation between genes and alleles, within a small or large group of people. A small group of people would for example be a family. A large group of people would for example be the population of a certain geographic region such as a country.

Glucose derivatives can produce a number of different molecules, including sugar acids. Below are three sugar acids. (1) Indicate which carbon has been oxidized in glucose to produce the sugar acid and (2) match the function of the sugar acid by selecting the letter associated with a description.

How is the end product of mitosis like the end product of binary fission?

Answers

Let's compare mitosis and binary fission.

Binary fission is a type of cell division characteristic for prokaryotic organisms that are unicellular. There are 4 steps in binary fission:
Step 1 Genetic material duplicates.

Step 2 Cell grows in size and other organelles duplicate.

Step 3 Cell wall or membrane forms.

Step 4 Cells separate into two new cells.

Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases -

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up.

2. Metaphase: Chromosomes line up at the centre of the cell.

3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

As can be seen, some steps are similar. And the end products in both cases are new cells. In mitosis, however, new cells are part of a multicellular organism while in binary fission, new cells represent new organisms.
