Answer:

<u>Isotonic</u>

Explanation:

If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.

Both the cytoplasm concentration and the glucose in the test tube are the same.

Artesian springs bring pressurized groundwater to the surface through which feature of Karst topography?
AnnZ [28]

Answer:

The correct answer is D) Fissures

Explanation:

Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.

Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.

Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

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.

In humans, random mating is most likely to occur for which of the following characteristics? Select one:B. personality C. physic
Andre45 [30]

Intelligence is most likely to be the criteria for random mating in humans.

Explanation:

If random mating is taking place on the conditions that no evolution is taking place the genetic pool will be maintained through generations.

Random mating will be based on intelligence in humans because this is the trait which gets exhibited only when showcased otherwise remains hidden while other characters like personality, appearance and athleticism are phenotypically expressed character.

Random mating is not under the influence of genotype. Intelligence is a trait which needs to be more in human as random mating takes genotype frequency in consideration.
