Osmosis is the movement from high to low concentrations with no energy
As blood glucose returns to its baseline level, the levels of insulin and glucagon in the blood will stabilize. As the blood glucose levels begin to drop below the base line, the concentration of glucagon hormone increases. while as the blood sugar levels increases above the baseline, the level of insulin hormones increases. Insulin and glucagon work antagonistically to maintain the normal level of glucose in the blood.
The answer is A. Applied forces are the unbalanced forces a person applies to another object to change its velocity or direction or to make it accelerate. When we pull an object towards us, we are increasing it’s velocity, so it’s an applied force.
