why would shuffling genetic material to produce new combinations of characteristics be advantageous to a species?
Radda [10]

Answer:

Suffling of genetic material increases genetic variation in offspring which is important for evolution.

Explanation:

Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.

In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.

Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.

Which of the following statements about a typical plasma membrane is correct?a. Phospholipids are the primary component that det
nordsb [41]

Answer:

B

Explanation:

The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.
