Alternative energy sources are those that do not deplete natural resources and do not harm the environment.
Options A, B, and C are all fossil fuels, which we know can be depleted and harm the environment.
The only valid option here is D, Geothermal energy.
Geothermal energy is both renewable and environmentally friendly.
Very high level atmosphere
Answer:
Explanation:
The cytoplasm in animal cells is surrounded by a membrane, which delimits the cell and its surroundings. As opposite from the plant cells, animal cells do not have a cell wall.
<em>Osmosis</em><em> is the process in which a solvent diffuses across a semipermeable membrane</em> (like the cell membrane) <em>from the zone with the lower concentration of solutes to the zone with the higher concentration. </em>That means that water, in this case, will diffuse spontaneously across the cell membrane from the place with more water molecules (usually, the exterior of the cell) to the place which has less water molecules, or is more concentrated (in this case, the cytoplasm). This diffusion will continue until an equilibrium is reached.
If we place an animal cell, which does not have a cell wall, into an environment with a low water potential, <u>the water will flow from the exterior to the interior</u>. If the water potential is very low compared to the one of the cytoplasm, the cell can receive too much water and explode. This process is called cytolysis.
They are all part of the Carbon cycle
Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.
Answer:
C would be the incorrect statement.
Explanation:
When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.
Hope this helps :)
