An interaction of systems allows for the body to warm itself when it is cold. Which processes help the body warm up when it is c
Dmitry_Shevchenko [17]

Answer:

shivering

hair on the body standing up

goosebump forming

Explanation:

The processes that help the body warm-up from the available options include <em>the shivering of the body</em>, <em>formation of goosebumps on the skin</em>, and <em>the standing up of hairs on the body.</em>

When the temperature of the body falls below the setpoint or the environment is cold, a homeostatic response is triggered and a signal is sent from the control center to the muscles of the body. <u>The muscles start shaking in order to generate heat to raise the temperature of the body</u>. At the same time, <u>the tiny muscles at the base of the hairs on the skin contract and pull the hairs erect, causing goosebumps in the process.</u>

In the video, the semipermeable membrane separates the two solutions of different concentrations. Watch the video and identify w
Zanzabum

Explanation:

A and D

A. A pressure equal to that of the osmotic pressure will result in reverse osmosis.

D. The movement of the solvent particles from the concentrated solution to the dilute solution is known as reverse osmosis.

During osmosis, water molecules from the less concentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

Thus, the water passes through the membrane due to the difference in osmotic pressure/ solute concentration on either side of the membrane, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.  

Water potential equal to the pressure potential shifts  the equilibrium, resulting in the movement of solute.

<h3>                              φ= φs+φp</h3>

However, in reverse osmosis, solute molecules move from regions of high solute concentration, to regions of low solute concentration across the membrane.
