B - They both use protein channels (I think so at least) they differ because active transports use a pump to leave the cell and it uses atp (cell energy).
Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
hope this helps have a nice day❤️
Explanation:
Cellular differentiation describes how different cells perform different processes and have unique functions. There are at least 250 cells in the human body and each one plays a different role, and <em>all</em> of them are crucial to the body's ability to maintain homeostasis. For example, liver cells produce proteins that are important in blood clotting. If these cells are damaged, blood will not clot properly. If blood does not clot, a body cannot maintain homeostasis and the person will fall ill.
TL;DR: every cell plays its part and keeps the organism alive.
Answer: cyclic
Explanation:
This pattern often fits in with daily body rhythms or with the sleep and wake cycle.
For example, Cortisol hormone accumulates early in the day, reduces towards the afternoon, and rises towards the end of sleep and maximizes during the morning hours.
Thyroid stimulating hormone (TSH) rises to the maximum point during sleep and reaches its low point three hours after the individual wakes up.
Growth hormone (GH) levels rise 90 minutes after sleep begins.
