What type of variation is nessary for natural selection to occur

Biology
1 answer:
grandymaker [24]3 years ago

Answer:

Genetic variation

Explanation:

Genetic variability (diversity) stems from two basic processes: mutation and recombination.

If there were no mutations, all genes would exist in only one form, they would not have alternative forms.

Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.

statuscvo [17]

Answer:

I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2

Explanation:

My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.

My glucose molecules were broken down into pyruvate, and I stayed that way  for a while, as I made my way to the mitochondria of the child's cells.  Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.

If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.

Zinaida [17]
The answer is letter C.
<span>
The interdependence of body systems is essential because all systems work together to maintain homeostasis. Homeostasis in body systems refers the regulation of internal conditions keeping it stable and relatively constant. In humans this refers to its ability to maintain stability in its internal environment while responding to changes in external conditions. It serves as a sensor that detects changes in the conditions that need to be regulated to meet the demands of the condition and give the necessary feedback. Regulation of body temperature and the balance between acidity and alkalinity are examples of homeostasis in the human body.</span>
