I think the weather will be rainy.
Answer:
C. placing cells in an environment with a lower solute concentration than that in the cells.
Explanation:
In pathological or diagnostic laboratories, to perform the differential leukocytes count (DLC) or white blood cells (WBC) count which are granulocytes, lymphocytes and monocytes we should first lyse the erythorcytes or red blood cells (RBC) with RBC lysis buffer. When RBC's lysis occur then only WBC's remain in the solution. Then, we add the hypotonic solution or lower solute concentration solution. By adding the hypotonic solution the cells will swell and increase in size.
So, the researchers used the hypotonic solution or lower solute concentration solution to increase the size of cells to differentiate between them.
Note:
In hypotonic solution the cells are increased in size or swell.
In hypertonic solution the cells are decrease in size or shrink.
In Isotonic solution the cells size remain same as normal.
The evolution of organisms are based on the resources available in order for it to be capable of growth still. In the given choices above, the substance or chemical that changed over time is the supply of carbon dioxide which is an essential substance for photosynthesis. Thus, the answer the first choice.
They can all travel through empty space
