Answer:

Mixtures can be separated by physical means.

Mixtures are made up of more than one component.

Explanation:

Mixtures are made up of more than one component and can be easily separated by physical means.

For example: A mixture of wheat and chaff can easily be separated by means of winnowing which is a physical method of separation. Air plays a very important role in separation. Chaff being lighter than wheat grain fall at a distance apart from wheat thus both of them get separated.

A cell come a certain organism has 64 individual, or 32 pairs, of chromosomes. Which of these can you draw?
Dmitriy789 [7]

Answer:

B. The cell cannot be a human

Explanation:

Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.
