In humans, DNA and RNA carry out various roles. DNA is responsible for genetic information storage and transmission, while RNA specifically codes for amino acids and serves as a protein-making messenger between DNA and ribosomes.

Answer:
The correct answer is a. sympathetic nervous system.
Explanation:
The sympathetic nervous system involves the rapid involuntary response called fight and flight response during stress conditions. In a stressful condition, our body parts give signals to the hypothalamus which stimulates the sympathetic nervous system of the body.
The activated sympathetic nervous system then stimulates the release of a hormone called adrenalin and nor-epinephrine from the adrenal gland. These stress hormone together with neural activity give rise to fight and flight response.
During this response our mind becomes alter, breathing becomes deep, heart rate becomes high, pupil diabetes, and excess sweating occurs. Therefore the correct answer is a.

A. A= or RNA, B= cell fuel and support, C= galactose and glycogen,
D= nucleic acids and fatty acids.DNA
Answer:
B) The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.
Explanation:
The Climate is constantly influenced by changes caused by the increase in global temperature called Global Warming. Global warming is caused by the emission of green house gases which includes carbondioxide (CO2). Hence, one way to prevent the climate from further deterioration is to find a way of removing gases like CO2 from the atmosphere.
Plants like trees and phytoplanktons like algae are photosynthetic organisms. This means they have the ability to perform the process of photosynthesis, which is the usage of light energy from sun to synthesize food in form of organic molecules (glucose) from an inorganic source. The inorganic source is Carbondioxide (CO2). Plants take in CO2 via the stomata on their leaves. Carbondioxide is a vital raw material for photosynthesis, hence, the photosynthetic process helps remove Carbondioxide from the atmosphere.
If trees, other plants, and phytoplankton are added to the biosphere, they will perform photosynthesis and absorb a good amount of Carbondioxide (CO2), which contributes to global warming, from the atmosphere. Hence, the temperature or warming of the atmosphere caused by global warming will decrease.
