Single celled organisms such as amoebas, especially those that live in fresh water, continually gain water from their surrounding environment by osmosis. This water is pumped into a contractile vacuole which fills with fluid and periodically fuses with the cell membrane, releasing its contents to the exterior. Thus the amount of water actively transported out of the cell is equal to the amount of water entering the cell due to osmosis and there are no variations in the tonicity of the cell. This is homeostasis at a simple level. Without the contractile vacuole, the amoeba would continue to absorb water until its cytoplasmic contents were diluted to such an extent that metabolism no longer occurred and it would die.
Its because a long spine cacti can reproduce more because it has more survival capacity than the short spine cacti and because of this reason the short spine cacti cannot protect it self because it has a shorter spine that could protect itself from danger.
False !!
when warm air rises low pressure zone is created not high !!
Answer:
B) splits carbon dioxide( mark me brainlest!)
Explanation:
In a nut shell , the light energy from the sun is converted into Chemical energy by the plants through the process of photosynthesis. The green pigment chlorophyll present in the leaves traps light energy from the sun . This light energy is used to convert water and carbon-dioxide into Glucose and Oxygen.
