In a population fulfilling all the assumptions of the Hardy-Weinburg equilibrium, allelic frequencies:
Rzqust [24]

Answer:

A. will not change from generation to generation.  

Explanation:

For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:

-The population is large enough.

-Individuals of the population exhibit random mating .

-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.

Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".

what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer​
olasank [31]

Answer:

Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).

Examples of where diffusion is important;

In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.

Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
