The cell cycle controls whether a cell continues to give rise to more cells or stop dividing and become specialized with a specific function to carry out. Humans begin life as a single fertilized egg cell that eventually gives rise to countless cells in an adult. As each cell divides it mus...
Explain the differences between a plant cell, an animal cell, and a bacterial cell. Identify the main differences between plant and animal cells. (a) How are plant cells, animal cells, and bacteria cells different? (b) Name at least 3 unique features of a bacterial cell compared to a euk...

Laboratory tests examine the biological, chemical and physical properties of the cells and molecules that make up a blood specimen. The first step is often to centrifuge a blood specimen into separate components. This divides the sample into one portion that contains solid components, such as cells...
Broadband works a completely different way. Instead of treating your phone line as a single, narrow pipe between your computer and the ISP's computer, like a dialup connection, it divides the line into many different channels. Information can travel in parallel streams down these channels. It'...
When a cell divides, it must reproduce its DNA so that each cell that results from the division has the samegenetic code. That means it must replicate its DNA. During this process, an enzyme called a helicase separates the two strands, breaking the hydrogen bonds between the A - T and ...
Although the original mutations occur only rarely in the sperm-producing cells, they encourage the mutant cells to divide and multiply. When the cell divides, it copies the mutation to each daughter cell, and the clump of mutant sperm-producing cells expands over time. Hence, the number of sp...

Adaptation time, which can be 70 or 400—represents the number of times the plasmid is in a transconjugant bacterium that divides until its cost decreases; Local neighborhood, 3 × 3 space centered on the bacterium—these are the spaces into which the bacterium can duplicate or where another ...
