The Answer is A. The presence of sodium potassium pumps has nothing to do with water moving in and out of cells.

The right answer is A.

Solutes have an influence on the water distribution inside and outside the cell, exerting an osmotic pressure.

The sodium-potassium or Na+ -K+ ATPase pump is a transmembrane protein whose enzymatic activity uses energy derived from the degradation of ATP to ADP and inorganic phosphate to transport K+ and Na+ against their concentration gradient. It plays a role in maintaining the resting potential of nerve, muscle and cardiac cells. The pump is used to exchange sodium ions (Na +) from the intracellular medium with K + potassium ions from the extracellular medium in a precise ratio (3 Na + / 2 K +). This pump is responsible for restoring the initial balance after an action potential.

Although the sodium ore itself has an influence on the water distribution by exerting osmotic pressure, the action of the Na-K pump does not influence it directly, it will just keep the most of sodium ions outside the cell.

weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

True [87]

Answer:

Gene: The hereditary material made up of alleles.

Alleles: The alternative forms of a gene.

Dominant: An allele or trait that masks the effect of recessive allele or trait.

Recessive: An allele or trait that gets suppressed by the dominant allele or trait.

genotype: The genome of a particular organism of the genes which make up an organism.

phenotype: The physical traits or characteristics of an organism.

test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.

law of independent assortment: Alleles of different genes get assorted independently into gametes.

law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.

product rule: Independent evens can be calculated by multiplying the independent probabilities.

Addition rule: The probability which shows that one event would occur in a mutually exclusive event.

co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.

incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
