A) Nucleic acids are necessary for life as they store genetic information in the form of DNA. Hope it helps!
Nucleic acids are the substances that are necessary for life. The correct option is A.
What are nucleic acids?Biopolymers and macromolecules called nucleic acids are necessary for all known species of life.
They are constructed of subunits called nucleotides, which are composed of a nitrogenous base, a phosphate group, and a 5-carbon sugar. Deoxyribonucleic acid and ribonucleic acid are the two primary classes of nucleic acids.
Natural chemical substances called nucleic acids are the main information-transporting molecules in organisms. They are particularly crucial in controlling protein synthesis. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two primary types of nucleic acids.
The preservation and expression of genetic data is a key role of nucleic acids. The information cells require to build proteins is encoded in deoxyribonucleic acid, or DNA.
Thus, the correct option is A.

During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for __________.
Answers
the repolarization of the cell.
Mechanism :
Action potentials are signals that are sent and received by muscle and nerve cells. Because of the negative concentration gradient in the resting membrane potential of nerve cells, there are more positively charged ions outside the cell than inside. There are more sodium ions outside the cell and more potassium ions within because these positively charged ions are sodium ions. Action potentials cause the membrane to depolarize, which is followed by the process of repolarizing the cell. The membrane potential changes and reverts to the negative value of the resting potential during repolarization. The potassium channels open and the sodium channels close at this stage, allowing the nerve cell to lose positively charged ions.

Which concept is part of the theory of evolution by natural selection
Answers
Answer:
New generations are better suited to survive than previous generations.
Explanation:
Darwin's evolutionary theory states that evolution is the slow process through which organisms change over time. Natural selection is the process by which evolution takes place. Variation in organisms, some of which offers an adaptive benefit, may be passed down from generation to generation. Better suited organisms will have a higher probability of surviving and procreating, and they will also pass on these phenotypic modifications to the offspring. Evolution is a long, protracted process because these phenotypic changes occur gradually across generations at the species level. As a result, it is anticipated that future generations would be better adapted to endure in the same environmental circumstances.

2.what is translocation ??,give the chemical equation for translocation
plss help will mark brainlest..
Answers
Transpiration is a water balance process mediated by stomata opening. Translocation is the transport process of photosynthetic substances from leaves to other tissues.
What is transpiration?Transpiration is a water balance process.
Through stomata opening and closure (which depends on how hydrated the plant is) water vapor is expelled from the leaves.
If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.By limiting water exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.
The equation to calculate transpiration is as follows,
E = Gv (Cvs - Cva)
Where,
E is transpiration.Gv is the total vapor water conductance.Cvs is the water concentration inside the leave.Cva is the air water concentration.What is translocation?Translocation is a fast and dynamic process through which photosynthetic products are transported from the leaves to other tissues of the plant to be used or stored.
This transport is done by the phloem cells through active transport or osmosis (depending on the substance).
The translocation of elements from the leaves to the roots is fast.
In conclusion,
The chemical equation for transpiration is E = Gv (Cvs - Cva). Translocation is the movement of photosynthetic products from leaves to other plant tissues.You can learn more about translocation and transpiration at

Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.
