In active transport particles move by making use of energy in the form of ATP.
<u>Explanation:</u>
Unlike in passive transport particles have to move against the concentration gradient in active transport. Thus particles require energy to do so and this energy is in the form of ATP. Osmosis and simple diffusion are examples of passive transport where substances move from a region of high concentration to a region of low concentration.
This movement is down the concentration gradient. In active transport particles move from a region of low concentration to a region of high concentration which is against the concentration gradient. Active transport is of two types.
In the first type called primary active transport energy is directly used in the form of ATP. In the second type called secondary active transport an electrochemical gradient created by ATP is used to facilitate the transport.
Answer: The new pressure of the gas is (A) 854.46 kPa.
The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.
The temperature is raised to 235 degrees K with constant volume.
Therefore,
Initial pressure 
Initial temperature 
Final temperature 
Final pressure
According to pressure law of gas,
( at constant volume)
Thus, the required new pressure of the gas is 854.46 kPa.
Answer:
Answer: Homozygous
Explanation:
An organism in which the two copies of the gene are identical that is, have the same allele is called homozygous for that gene.
A. off a surface at the same angle it strikes the surface
