What is the definition of biological evolution and what does it have to do with populations?

Biology
1 answer:
katrin [286]3 years ago
6 0

Answer:

Definition:

Biological evolution is the process through which the characteristics of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations."

A small change in genes could result in a mass epidemic. Such as the colinistists bringing yellow fever over to America.

Explanation:

Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.

tatiyna

Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Alborosie

Answer: 5

Explanation:

Since 1 out of 200 people carry the defective gene that causes inherited colon cancer.

In a sample of 1000 individuals, we say

1 = 200

y = 1000

cross multiply

y x 200 = 1000 x 1

200y = 1000

y = 1000/200

y = 5

Thus, in a sample of 1000 individuals, approximately 5 will be carriers
