a.

Summary Introduction

To describe:

The number of bacterial cells that are present 3 hours after introducing 20 bacterial cells to the pasta salad, assuming that the generation time is 20 minutes.

Concept introduction:

Exponential growth involves a growth in the cell population by a factor of 2. These populations contain a high number of cells; therefore they are represented as exponents. When the exponential number and time graph is plotted, the line comes out to be straight, representing exponential growth.

Doubling time is the time taken by a bacterial cell to form two daughter cells, after completing a fission cycle. It is also referred to as generation and is a constant process under favorable conditions. In bacteria, each doubling time leads to a doubling of their population. This process leads to an exponential growth in their population. Each exponent represents a generation in exponential growth.

Find the dental formula and enter it in the following format: I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format) Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
