Using a video camera connected to a microscope , a scientist records a time-compressed video of one animal zygote dividing over 40 hours. Which claim is best supported by this recording? A. Cells only occur in a living organism. B. Cells can be broken down into organelles. C. Cells are created from cells that already exist. D. Cells cannot reproduce independently without the machinery of a host cell.

## Step 1<br />The problem presents a scenario where a scientist records a time-compressed video of one animal zygote dividing over 40 hours. The zygote is a single cell that divides to form two cells, which is a process known as cell division.<br /><br />## Step 2<br />The question asks us to identify the claim that is best supported by this recording. The options provided are:<br />A. Cells only occur in a living organism.<br />B. Cells can be broken down into organelles.<br />C. Cells are created from cells that already exist.<br />D. Cells cannot reproduce independently without the machinery of a host cell.<br /><br />## Step 3<br />We need to analyze each option in relation to the scenario presented. <br /><br />## Step 4<br />Option A, "Cells only occur in a living organism," is not directly supported by the recording. The recording only shows the division of a single cell, not the existence of cells in a living organism.<br /><br />## Step 5<br />Option B, "Cells can be broken down into organelles," is not supported by the recording. The recording only shows the division of a single cell, not the breakdown of cells into organelles.<br /><br />## Step 6<br />Option C, "Cells are created from cells that already exist," is directly supported by the recording. The recording shows a single cell dividing to form two cells, which supports the idea that new cells are created from existing cells.<br /><br />## Step 7<br />Option D, "Cells cannot reproduce independently without the machinery of a host cell," is not supported by the recording. The recording only shows the division of a single cell, not the reproduction of cells in a host cell.
