Norma-Jean [14]

Answer:

Louis Pasteur, by observing that the microbes were in the air and contaminated the broth helped determine that all the cells came from pre-existing cells (option b), one of the postulates of the cell theory.

Explanation:

Louis Pasteur's experiments, conducted around 1860, showed that unicellular organisms appeared in a culture broth only if it was exposed to the air, where other microorganisms were present, thus disproving the hypothesis of spontaneous generation.

On the other hand, in the broth that was not exposed to the air Pasteur did not observe microorganisms.

By rejecting the hypothesis of spontaneous generation through his experiment, Louis Pasteur reaffirmed the postulate of the cell theory that proposes that all cells come from preexisting cells.

The other options are not correct due to:

<em>    a and c. </em><em><u>All animals are made of cells </u></em><em> and </em><em><u>cell is the basic functional unit of living things</u></em><em> are postulates of the cellular theory that were not demonstrated by Pasteur's experiment.</em>

<em>     d. </em><em><u>Unicellular organisms inherit an exact copy of DNA from the parent cell</u></em><em>​ is not a postulate of cell theory.</em>

I need help pls...
Alina [70]

Answer:

C

Explanation:

<em>The possible genotype of his father is </em>X^RY<em> and </em>X^rY<em>.</em>

<u>For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.</u>

The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.

Hence, in this case, the father can either be affected for the same trait (X^RY) or be free from it (X^rY).

The correct option is C.
