How do molecules in certain molecular compounds come to have a slight electrical charge ?
solong [7]
Atoms of some elements pull more strongly on shared electrons than do atoms of other elements, as a result, the electrons are pulled more toward one atom, causing the bonded atoms to have a slight electrical charge.

The change in allele frequencies that occur due to the colonization of a new location by a small group of individuals is called
Shalnov [3]

Answer:

Founder effect.

Explanation:

The founder effect is a case of genetic drift in which a small population sample of a limited number of individuals is shed from a larger population, its gene pool carrying only a part of the genetic diversity represented in the source population. Thus, it is likely that the genetic destinies of the population of origin and of the new population are established in different ways. When a new generation has randomly distributed alleles, with a large enough sample size, we can expect that the gene pool of the new generation will more or less represent the gene pool of the previous generation.

During the process of photosynthesis,
TEA [102]

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.
