Answer:
Population of cactus like plants which grows in the hot and dry weather of deserts,begins the flow of energy in the desert food web. Because plants are the only producer of energy in every food web.
Explanation:
Answer
Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.
Serve as the selective channels for the influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.
Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.
Separation of metabolic process in the cell.
Explanation:
Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its constituents, it is made up of lipids, carbohydrate, protein and cholesterol
A search method employed by two or more people overlapping separate line searches forming a grid.
Not to sure tho hope this helps
The overall mechanism of cellular respiration<span> involves four subdivisions: glycolysis, in which glucose molecules are broken down to form pyruvic acid molecules; the Krebs cycle, in which pyruvic acid is further broken down and the energy in its molecule is used to form high-energy compounds such as NADH.

Answer:
1. transcription of Tau DNA in different directions.
4. different chemical modifications of Tau protein.
Explanation:
Tau gene transcribe in different direction which depends upon the animal age. This happens because at different age and developmental stage, animal produce different RNA binding proteins which leads to formation of alternative splice forms. This reaction is strengthen by the addition of phosphate and sugar molecules which again depending on developmental stage and time.
