Answer;
-Down the concentration gradients; evenly distributed
Diffusing molecules move down the concentration gradients until they are evenly distributed.
Explanation;
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.
-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
Answer:
I would guess so.
Explanation:
It would seem like something that they would do to get away with using it because they wouldn't want to pay fines.
