Answer:

C. Osmosis

Explanation:

Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.

Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.

Osmosis is controlled to a large extent by concentration gradient.

Diffusion on the otherhand is the movement of molecules of a substance from one position to another.

Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.

Answer:

a. Two of these are correct.

Explanation:

The two correct options are

b. Is a critical component or requirement for wound healing to take place

d. Existing blood vessels give rise or sprout to form new blood vessels

Angiogenesis is the physiological means in which new blood vessels form pre-existing vessels, developed in the starting phases of vasculogenesis. Angiogenesis is a usual and important process in growth and development, wound healing and in the development of granulation tissue.

The growth and maturation of blood vessels is a largely regulated multistep mechanism called angiogenesis.

A normal chromosome and its homolog carrying an inversion are given. the dot (•) represents the centromere. normal: a b c • d e
kotegsom [21]

The type of inversion is Paracentric inversion.

There are two types of inversion at the chromosome level, depending on the centromere:

Paracentric inversions:

the centromere is not included in the inversion.

Pericentric inversions:

The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.

the structure that will form during synapsis is inversion loop.

These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.
