Answer:

Three Laws of Biology. “Social rules can be broken, but the laws of nature can't.”

A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms. Many of these regularities of ecology and biogeography are named after the biologists who first described them.

A group of researchers wanted to sort different white blood cell types (monocytes, lymphocytes, and granulocytes) apart from eac
maks197457 [2]

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.

Which of the inner transition metals is critical to the nuclear power industry.
Rom4ik [11]

Answer:

<u>Uranium</u> is the  inner transition metals is critical to the nuclear power industry.

Explanation:

Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.
