Answer: Option (b) is the correct answer.

Explanation:

A nuclear particle which is positively charged is known as an alpha particle. An alpha particle is emitted during a radioactive decay.

Mass of an alpha particle is similar to mass of a helium atom, that is why, a helium atom is also known as an alpha particle.

Therefore, an alpha particle is denoted as ^{4}_{2}He. That is, there are 2 protons and 2 neutrons in an alpha particle.

Thus, we can conclude that an alpha particle is identical to the nucleus of a helium atom.

Answer;

-Helium atom

Explanation;

-An alpha particle is identical to the nucleus of a helium atom.

-Alpha particle is one type of particles emitted during a radioactive decay, others being gamma and beta particles. Alpha particles are produced during the process of alpha decay.

-When an alpha particle is generated during a radioactive decay, the mass number of the radioactive particle increases by 2 while the atomic number increases by 4.

1. What is the most common method large businesses use to communicate their views on environmental issues to legislators?

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.
