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.
Answer: the National Pharmacy Technician Associations
Explanation:
NPTA, the National Pharmacy Technician Associations, is the world's largest professional organization established specifically for pharmacy technicians. The association is dedicated to advancing the value of pharmacy technicians and the vital roles they play in pharmaceutical care.
Answer:
The statement is totally supported in accordance with the data.
Explanation:
As we can see a pattern in the given data where exposure to ambient lightning conditions of Room light, Night light and totally dark environment, the rate of myopia is decreasing gradually according to the above order.
For more accurate results, the study can be made broader by taking in more and more candidates because the more number of data sets we have the more statistically accurate results we'll get.
Answer:
Primary active transport
Explanation:
Active transport may be defined as the movement of particles against their concentration gradient with the help of an energy source like ATP. Two main types of active transport are secondary active transport and primary active transport.
Primary active transport includes the sodium potassium pump because it directly uses the stored chemical energy in the form of ATP. Three sodium moves out of the cell and two potassium moves inside the cell with the help of ATP.
Thus, the correct answer is option (a).
Answer:
Explanation:
The bone is being destroyed by osteoclasts faster than it can be rebuilt by osteoblasts. A lot of factors can contribute but osteoporosis affects mostly post-menopausal women due to their hormone levels
