Answer:
The correct option is<u> slight increase in salt concentration in the
</u>
<u>environment.</u>
Explanation:
The main function of contractile vacuole in the body of a paramecium is to pump out excess water. But an increase in salt concentration in the environment will let the water move inside the cell by osmosis. Hence, the contractile vacuole will not perform its function and will not be able to regulate osmoregulation.
Other options are incorrect because slight changes in the temperature or pH won't affect the contractile vacuole and it will still be able to perform its function.
Answer:
the answer is: A) growth of actin filaments to form bulges in the plasma membrane.
Explanation:
Amoebas are unicellular organism that can move on a surface using pseudopodia (false feet). This kind of movement is called amoeboid movement. The amoeboid movement is explained by the Sol-gel theory. The protoplasm of the amoeba is made of an outer gelatinous layer, and an inner portion made up of plasma sol. The sol-gel theory explains the contraction and relaxation events in the protoplasm of the amoeba that lead to the pseudopodia.
Answer:
As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.

If Plants no longer existed on earth then there would be no way for carbon dioxide to be converted into oxygen, without oxygen animals and humans alike would die. The Worlds "Air" would be toxic for us to breathe, we need plants to survive. Without plants, animals would die of starvation, and predators would as well without substance.
