characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate.
