Red blood cells (a good, colorful example of an animal cell type) when placed in pure water swell up and eventually explode. Why
would these cells swell up? What does this tell us about the solute concentration inside the cell compare with the pure water? Why do these cells eventually explode?
When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.
As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
The answer would be C because photosynthesis takes in carbon dioxide and water and produces oxygen and glucose. Along with this animal cells do not contain chloroplasts
Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
