Answer:

The correct answer is option B. The less porous the less permeable.

Explanation:

The porosity of a solid is a character that explains how much the space present between the grains of the solid. The rocks with more space in its grain have high porosity.

Permeability is the ability to pass a liquid through itself and it is closely related to the porosity. The more porosity the more permeability and vice verse.

Thus, the correct answer is option B.

B) the less porous, the less permeable

Porous means "full of holes."

Permeable means "stuff can go through it."  

The more porous something is, the more permeable it is.

zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.

Drupady [299]

Answer:

The new drug will not be effective against the treatment of cancer.

Explanation:

The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.

Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
