When doctor Blackwell induced a lesion in the rats' medulla, he discovered that the rats stopped breathing. He explained this observation by saying that the medulla has functional role to play in the breathing process of rats.
Answer:
A genetic screening test is more likely to detect genetic disorders.
Explanation:
A genetic screening is a tool used in the field of genetics to investigate the normal configuration and alterations in genes. It is based on the identification of an individual's DNA, proteins and chromosomes.
<em>One of the main functions of genetic screening is the </em><em>detection of genetic disorders</em><em> in an individual, before or after birth.
</em>
Phenotypic expression or severity of disease are physical or functional expressions of genetic disorders, while treatment are the specific actions for these disorders.

Explanation:
Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
I hope this helps. If not I am really sorry!
