A double helix structure that consist of two polynucleotide chains.
A DNA molecule consists of two strands that wind around each to form a double helix. Double-stranded DNA consists of two polynucleotide chains.
The statement "The correct way to calculate population size is by dividing the total population by the land area." is true. The correct option is A.
<h3>What is the population?</h3>
The entire number of species in a given area makes up the population. Surveys of various places are conducted to determine the population. By dividing the total population by the fraction of each individual, the population size can be determined.
There are various techniques for population counting. Cohort analysis, aerial counts, etc., are some of these techniques.
Thus, the statement is true. The correct option is A.

Answer:
d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds
Explanation:
Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.
During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.
The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.
