Hello.
Water is necessare because it leads to <span>Photosynthesis that lets plants grow.
Have a nice day </span>
Answer:
Global Warming
Explanation:
First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms. This shift of liquid water from land to ocean is largely due to groundwater pumping.
The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
Answer:
Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
Meiosis is the process in which a single cell divides twice to form four haploid daughter cells.
I'm not sure what you're trying to ask but here are some simple definitions for mitosis and meiosis.
