What factor helps determine the fertility rate of a group of people?

Biology
2 answers:
myrzilka [38]3 years ago
6 0
The correct answer is - A. Death rate.

We get the fertility rate from the birth rate and the death rate. More specifically, from the number of the children that are born in a given time frame (usually a year) we minus the number of the people that have died in the same time frame, so the difference between them gives us the fertility rate.
The fertility rate can be positive (in the difference is a positive number) and negative (if the difference is negative number).

tino4ka555 [31]

Answer:

The correct answer is - they both have highly folded membranes.

Explanation:

Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.

As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
