The best answer is B.
DNA is sometimes referred to as the blue print of the cell's information because it is the store house in which all genetic information necessary for the cell's survival and reproduction is kept.
Without DNA, there cannot be any continuation of life and no new generation of organisms. All living cells and organisms are essentially made up of protein in different forms. Apart from water, proteins are the most abundant molecules in the cell and body where they serves as the major structural component and are essential for growth and maintenance. Information for all these proteins is found in DNA. Without DNA, there can be no protein hence no life.
The salinity is the concentration of salt in a given liquid. So the answer is 'the water has a salt concentration of 35 parts per thousand'.
The mitochondrial structures are the site of the enzymes and carriers used to make ATP in the electron transport system are CRISTAE. These membrane structures form mitochondria.
<h3>
Mitochondria and cellular respiration</h3>
Cellular respiration refers to the metabolic reaction by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods.
The Krebs cycle and oxidative phosphorylation are steps in cellular respiration that occur in the mitochondria.
A crista or cristae (plural) refers to a fold in the inner membrane of mitochondria, which is required during cellular respiration.

Primary succession is when, for example, a volcano explodes and there is nothing left and even the soil is ruined. It would take at least a hundred years for the land to be like it was before the volcano erupted. Secondary succession is when, for example, a wild fire happens but the soil is not ruined. It would take at least 25-50 years for the land to be like it was before the fire.
Answer:
b. allele
Explanation:
An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).
<u>The other options are wrong because:</u>
The genotype is the combination of alleles an individual has.
The karyotype is an individual's collection of chromosomes, paired and ordered.
A homozygote individual has the same alleles for a particular gene.
A heterozygote individual has different alleles for a particular gene.
