Short answer

The correct answer is a. He/She looks for abnormal-appearing cells.

Step-by-step solution

Identify the question

First, let's understand what the question is asking. The task is to find the correct statement that describes what a doctor looks for to diagnose cancer after performing a biopsy.

Analyze the statements

Read all four statements and analyze them to understand which statement is the most accurate to describe the process. a. He/She looks for abnormal-appearing cells. b. He/She sees if the cells can divide. c. He/She sees if the cells will respond to growth factors. d. He/She sees if the chromosomes have telomeres.

Find the correct statement

We have analysed all the options, and the correct statement is: a. He/She looks for abnormal-appearing cells. The reason behind this is that when a doctor performs a biopsy, they are specifically looking for any abnormal cells or irregularities in the tissue that might indicate the presence of cancer. The other statements may be related to different aspects of cell behavior but are not the primary factor a doctor looks for to diagnose cancer from a biopsy.
