The answer is immigration rate minus emigration rate.

Emigration is a movement of organisms from the region of settle. So, when organisms leave a population, they emigrate.

Immigration is the opposite process of the emigration in which organism move to some area. 

Population change depends on several factors: birth, death, immigration and emigration. If population size is increased, then the death rate must be less than the birth rate. Also, emigration rate must be less than immigration rate. So, to increase population it is necessary for birth and immigration to be higher than death and emigration.

Countercurrent multiplication involves A) ions leaving ascending limb to make water come out of the descending limb B) water lea
Snowcat [4.5K]

Answer:

The correct option is A

Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.

Explanation:

Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.

Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.

Scorpion4ik [409]
Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.
