The continents we know today were previously clumped together in a super continent called Pangea.
Anna35 [415]
For hundreds of millions of years, all the land of Earth was joined together in one large mass or super continent. Scientists call it Pangaea (meaning “all lands” in Greek). Then about 200 million years ago the land began to drift apart. It broke into two pieces, and scientists have called the continent in the north Laurasia and the continent in the south Gondwanaland (named by Eduard Suess, an Austrian geologist).  The two large continents continued to break apart into the smaller continents that exist today. Scientists call this movement ‘continental drift’.

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>
