Hey!
The water cycle is driven by solar energy, see solar energy is what makes water evaporate, which needs to happen for precipitation to happen, and precipitation reaches earth in hail, snow, or rain which will run-off into oceans and evaporate or just eventually evaporate.
So, yes, solar.
Because people use too much gas and oil. If they made plant biofuel people wouldn't spend a lot of money and we wouldn't waste oil.
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.
Answer:
Jim's heart rate decreased quickly after 30 minutes since he is in good shape.
Explanation:
Explanation: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
