Which of the following polymers provides protection in the plasma membrane?

Lipids polymers protects the plasma membrane

Explanation:

The plasma membrane is made up of lipids and proteins.The lipid content is more than compared to protein.The plasma membrane is permeable  in nature due to the presence of lipids.It protects the internal organelles of a cell from the external environment.Protein content in plasma membrane transports nutrients to the membrane.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
