Answer:
Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.
Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
Pre-mRNA is the polymer is synthesized during transcription, it is different from polymer being copied in having U instead of A.
A DNA fragment is copied into RNA during transcription. Messenger RNA is the term for DNA segments that are translated into RNA molecules that can encode proteins. Non-coding RNAs are RNA molecules that contain copies of additional DNA segments. Only 1% to 3% of all RNA samples are mRNA.

The correct answer is the loss of genetic variation. This is because after genetic drift, the original poulation of a species decreases in number, and the new dominant genes in the population will live up to reproductive age, and increase the newer genes will thrive.

Answer:
E. A, B, and C are correct answers.
Explanation:
A male reproductive system is an organ system that produces sperm also called the male gamete. the male organ consists of two main structures which are penis and scrotum.
A female reproductive system is an organ that produces female gametes. it is a place where the male drops their sperm for fertilization during sexual reproduction.
a very A major difference between the human male and female reproductive tracts is the
- Temperature at which gamete production occur
- the location of the gonads
- also the fact that the scrotum houses testes and the ovaries are covered by protective capsule.
That is why i chose E because A, B and C are the correct answer.
