Fossils can provide the time a species existed through carbon-14 dating, and can also show structures within the species that are similar to other organisms on earth today or other organisms before/slightly after that fossils existence.
There was an abundanze of butterflies, like supermarkets have oberflow of butter :DDDD
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 gender is male. I just know.....
If the conclusions do not support their hypothesis they would start the experiment all over again and see what they did wrong. <span />
