B. The prefrontal cortex is used to plan complex cognitive behavior, personality expresison, and moderate social behavior.
In humans, identical twins are possible because C. early blastomeres can form a complete embryo if isolated.
Identical twins are formed when an egg after fertilization by a sperm gets divided into two.
The early blastomeres are totipotent cells which means that they have the capability to form all the cells of the body further. Hence, if an egg after fertilization splits into two, it has the potential to form a complete embryo which forms an individual.
However, as the splitting process has occurred after fertilization, hence the two individuals formed will be identical twins. The genome for the identical embryos will be identical.
Identical twins are also referred to as monozygotic twins as they arise from a single egg or zygote.

Answer:
1.9mL to 8.7mL (Answer A)
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).

Sunlight, humidity, soil type, temperature
