Answer:

C. Water molecules flow in both directions at the same rate.

Explanation:

The relative concentration of solutions indicates the direction of movement of water across the semi-permeable membrane. An isotonic solution is that which has the same osmolarity of a cell. As a result, there is no concentration gradient for water across the cell membrane. In this case, water molecules will move through the plasma membrane in both directions with the same rate. Thus, there will be no net movement of water into or out of the cell.

Which of the following statements best provides evidence of the big bang theory?
Oxana [17]

Answer: D. Galaxies show a red shift, indicating they are moving away from each other.

Explanation:

Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.

This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.

Before the Industrial Revolution (top picture), the bark of the trees was
-BARSIC- [3]
This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.

Which option identifies the outcome of the following scenario?
JulsSmile [24]

Answer:

I believe the answer is 'She will have a high energy level due to the carbhohydrates in the bread group'

Explanation:

or The reason is that Carbs are sugars and sugars are known to give you energy if you don't overdo the carbs/sugars. Marianne had the tuna sandwich for lunch then pasta for dinner but for breakfast, she had eggs that are protein so she could have energy starting from breakfast then had lunch which carried on that energy.

Hope this helped :)
