Edmentum's sample answers

Explanation:

- Part A: The picture of Archaea bacteria in the video showed that the organism was made of a single cell, and it had a defined border. Scientists also know that it reproduces by passing on its genetic information because there is evidence of Archaea’s genes in our DNA today.

- Part B: Both cells had a clearly defined border. However, the bacterial cells were rod-shaped, and the human cells were round. The human cells had a clearly defined nucleus and other structures within the cell. The bacteria had a darkened place in the center, but it was not a clearly defined nucleus. Also, the bacteria are single-celled organisms, while humans have many cells. The bacteria are prokaryotes, and the human cells are eukaryotes.

- Part C: They live in extremely hot environments. So, they would need to have some mechanism to control their internal body temperatures.

- Part D : Do you think the gene EEF1 ALPHA1 supports cell theory? Explain your response

The gene EEF1 ALPHA1 supports cell theory. Cell theory states that all living things are made from cells. Since all living things share this gene that dates back to an organism that lived billions of years ago, it makes sense to conclude that all living things originated from the earliest forms of life. This conclusion would explain why all living things on Earth are made of cells.
