Compare and contrast point mutations and chromosome mutations and explain the basis for classifying a mutation as beneficial, ne
zepelin [54]
<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>

IRISSAK [1]

Answer:

See explanation

Explanation:

There are three main aspects of photosynthesis

(i) Absorption of light energy by chlorophyll.

(ii)Photolysis of water

(iii) combination of water and CO2 to form carbohydrates.

The second and the  third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.

Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.

the Arizona poppy,  lie dormant during drought only to germinate, grow, flower, and yield seeds a few weeks after the rains return.
