Answer:
B
Explanation:
RNAi is a cellular mechanism for post-transcriptional gene silencing. After transcription of a gene into mRNA, small interfering RNA (siRNA) and microRNA (miRNA) can target the mRNA to form dsRNA. This mRNA then becomes a target of ribonucleases such as the Dicer that break it apart. These mRNA, therefore, do not reach the cytoplasm for translation by ribosomes. This mechanism is hence harnessed and manipulated by scientists to study genes by silencing them.
Here is your answer

Answer:
a) and d)
Explanation:
An homeostatic process is the process that allows the body to <u>reach and maintain an state of equilibrium</u>, this process allows the body to self-regulate itself and therefore when it detects that some parameters are out of range, it works to get those parameters back to where they are supposed to be.
Therefore, the definition of a homeostatic process contains two basic statements:
a) The maintenance of certain body variables within a fixed range.
d) The process that reduces the deviations from the set point.
<u>ANSWER:</u>
Areas near the Earth's <u>Equator</u> receives more sunlight than areas near the <u>Poles</u>.
Option: 1. A. Equator , 2. B. Poles
<u>EXPLANATION:</u>
- The areas near earth's equator receive more sunlight than areas near pole i.e areas near equator are hotter than areas near pole as the sun's rays hit the earth's surface at the equator at a higher angle, almost vertically i.e right angle which is not the case at poles of the earth.
- Hence, equator is said to receive more sunlight than the poles of the earth's surface.
