It is critical that all of a cell's DNA \( \checkmark \) is copied during the synthesis phase before cell division because the cell will divide into two \( \checkmark \) new cells. The DNA must be copied so each daughter \( \checkmark \) cell receives a full \( \quad \) set of genetic information.

A bacteria culture starts with 500 bacteria and doubles in size every 3 hours. Write an equation representing the population of the bacteria after \( t \) hours.

2. Which is a method that tuberculosis is spread? Touching surfaces, other people, or dirty linen Tuberculosis particles stay in the air for a long time and can be inhaled Tuberculosis can only spread through sexual contact
