When you are running at high intensity many body systems are being influenced by running and providing some responses in your body.
Running stimulates the cardio respiratory system, making your heart work harder by pumping a large amount of blood into your body, the blood flow starts to be fast and to compensate for this effort you will have to breathe more, taking more oxygen for your organs and tissues.
The muscular and bone systems are stimulated and trained providing greater resistance and strength for your muscles and lower bones.
During the run, the urinary system is also affected, because running is able to improve kidney function, allowing the expulsion of toxic substances from your body to be done more efficiently.
Finally, running stimulates the endocrine system by causing it to release hormones of well-being and relaxation that help you rest and feel good after running.
Answer:
C) The cell membrane allows water to enter and leave the cell.
Explanation:
The cell membrane is a selectively permeable membrane that allows certain non-polar and small substances to move through it. Water is allowed to move freely through the cell membrane according to the concentration gradient. After the removal of shells, the membrane served as the outer most covering of eggs.
When placed in a different solution, the water moved in or out of the cells depending upon the concentration gradient. If the egg cells were placed in a hypotonic solution, water will enter into the egg cell resulting in the increase in its volume. On the other hand, when an egg cell is placed in a hypertonic solution, water leaves the cell through the cell membrane and the egg shrinks. This passive movement of water through the cell membrane is called osmosis.

A. direct B. indirect C. direct D. indirect
Competition occurs by direct and indirect means. Organisms interact directly by fighting (aggression) for scarce resources. Two eagles fighting over the salmon carcass and two colonies of ant clashing over a wasp are samples of aggression (direct competition)
Indirect competition happens when there is a common or limited <span>supply of at least one resource (food, water, and territory). </span>Use of this resource lessens and later depletes the amount available to others, or they compete for space.<span> Gray foxes preying on penguins and squirrels relying on nuts for food are samples of indirect competition.</span>
