A cell biologist treated some cells with a stain. She found that the stain was concentrated within the mitochondria of many types of cells. Which conclusion could the cell biologist draw regarding the results of this test?

A.
The stain could be used to identify mitochondria in living cells.
B. The stain could be used to determine if cells were alive or dead.
C. All stains will be absorbed by mitochondria.
D. All mitochondria create stains.

The conclusion that can be safely drawn is that "The stains could be used to identify mitochondria in living cells"

Step-by-step explanation:

Mitochondria are the powerhouse of the cells. It produces energy molecules (ATP molecules) to power various cell functions. Hence mitochondria are associated with living cells.

As provided biologist treated some cells with stains and later she found that these were concentrated in the power-house of the cells.

Since the Biologist found that stains were concentrated within the mitochondria of many of the cells, hence it can be safely argued that stains(which are present in the mitochondria) can be used to confirm the mitochondria in those of living cells.

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
