Factors that determine the rate of stream erosion-
➡️ Rainfall (more rain more erosion). ✔️
➡️water velocity ✔️
➡️shape, size and depth of channel ✔️
➡️stream capacity to transport eroded material, and the nature of the material being transported✔️
➡️Gradient (Steepness or slope) ✔️
➡️Discharge (Amount of water carried at a given time) ✔️
➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️
➡️Slope (the steeper the slope the faster the water will flow) ✔️
➡️Geology (if the bedrock is a soft silt it will erode faster than granite).✔️
False, the arrow for C is pointing to the genetic material of the virus cell. The capsid (protein shell) is A.
It is by simple diffusion that enables the gases of O2 and CO2 to enter and leave the plant cell. It is because the simple diffusion enables substances to be able to process in which they are able to pass in a membrane. By passing in the membrane, they don't need any help of others or any aid and could pass with simply their own.
Answer:
The role of the cholesterol molecules in the phospholipid bilayer can best be described as cholesterol molecules maintain fluidity and integrity of the membrane.
Explanation:
Cholesterol is a component of the cell membranes, the content of which is almost a quarter of the lipid composition of this structure.
The number of cholesterol molecules in the lipid bilayer represents a barrier that prevents substances from passing through it, and one of its most important functions is to <u>collaborate with the organization of the fatty acids that form part of each layer, preventing their tails from fusing</u>, which guarantees the fluidity and integrity of the membrane.
