C) Urea
Explanation:
Wohler was a German chemist who was known for his Urea experiment in which he was able to produce organic substance from the inorganic substance.
While he was working on the experiments where he could get cyanide as a product on heating, one day for which he heated the ammonium cyanate (inorganic substance) and got crystals with other physical and chemical properties called urea (organic substance).
Thus, C) Urea is the correct answer.
Ovulation and ejaculation respectively
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>
