Answer: Varies
Explanation:
It all connects to the afterlife being a real thing.
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
Answer:
<u>Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.</u>
