Answer:
The answer to the question: The nephron uses counter-current exchange between the Loop of Henle and peritubular capillaries to reabsorb glucose back into the blood as this is why glucose should not be found in the urine:___, is, false.
Explanation:
The process of urine processing as filtrate goes through a nephron´s different portions, is pretty complex, but fascinating. Initially, water, certain substances as glucose, sodium, and others, pass through the glomerulus intoo the PCT (Proximal convoluted tubule) where the initial filtrate is formed. This filtrate will then move through other portions to be added to, and substracted from, on different elements, until finally, at the very end, urine is produced. However, one molecule that is reabsorbed early in this process of filtrate production, is glucose. Glucose should not be usually present in urine, unless there has been a huge consumption of it and transporters in the PCT cannot deal with the amount being filtered, or there is a condition like diabetes mellitus. It is in the PCT that glucose reabsorption is done, together with sodium ions. This is why the answer to the statement is false.

Answer:
Satellite cells.
Explanation:
Neuroglia cells is present in the both the central nervous system and peripheral nervous system. Neuroglia cells are involved in the exchange between neurons and capillaries.
The main neuroglis cells of the peripheral nervous system are schwann cells and satellite cells. Satellite cells support the neurons and helps them in their nutrient supply.
Thus, the correct answer is option (B).
Answer:
Antiseptics can be used on living tissue
Explanation:
Answer:
Concentration, Temperature, Mass of Particle, Solvent /medium, surface area and permeability properties of membrane.
Explanation:
The random movement of particles causes the phenomenon called diffusion. The concentration gradients of particles pushes molecules in a direction such that molecules move from a region of high concentration to a region of lower concentration.
Diffusion is a passive process (not requiring the input of energy).
The following variables are factors that affects diffusion;
Concentration - down concentration gradient favours diffusion.
Temperature - temperature increases diffusion , the kinetic energy associated with each particle also increases.
Mass/size of Particle - Smaller particles on the other hand will diffuse faster because they can move faster.
Solvent /medium Properties - Viscosity and density of the medium greatly affect diffusion. Highly viscous and dense medium slows down diffusion.
Diffusion can occur through a membrane. The two factors that are particular to diffusion through a membrane are surface area and permeability.
