The structure shown in Figure 10-5 is a replicated chromosome. The smaller a cell is, the more difficult it is for the cell to move enough nutrients and wastes across its cell membrane to maintain its normal functions. During cytokinesis, a cell undergoing cell division finally splits into two daughter cells.

Your health can depend on your knowledge of biology. Knowing the nutrients you need, the causes of diseases, and the things you should avoid, such as cigarettes, can help you lead a longer, healthier life.

Homeostasis is the ability of an organism to regulate its internal environment. In homeostasis, an organism maintains a constant state relative to the external environment. One example of homeostasis is the way humans maintain a stable body temperature even when the outside temperature changes.

Will all biology questions be answered some day? No because our environment is constantly changing.

The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material. The cell cycle is complete when each daughter cell is surrounded by its own outer membrane.

An issue is a topic of discussion, or something that can raise concerns. Why is biotechnology sometimes called an issue? Scientists haven't created the technology to answer them yet (don't understand yet).

What does Figure 10-10 represent? How do you know if this is an animal cell or a plant cell? Figure 10-10 represents m phase in the stages of prophase,metaphase, anaphase, and telophase. This is an animal cell because of the shape of the cell that is more round.
