<h2>Mutation of p53 Gene</h2>
Mutation in the p53 protein leads to uncontrolled cell division of tumor cells leading to metastasis of tumor.
Explanation:
The p53 gene termed as the tumor protein or TP53 is the gene that encodes the regulatory protein which regulates cell cycle and cell death (apoptosis). Cell cycle and apoptosis are the important factors which prevent proliferation of cells with abnormal DNA. P53 acts as the tumor suppressor and prevents the spread of tumor or cancer. Mutation of p53 gene could be inherited or caused due to chemical, biological, or radiation mutagens. A mutant p53 actually inhibits the action of a natural p53 and thereby inhibits tumor suppression.
Answer:
How do nutrients move through an environment? What drives the movement of nutrients?
My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.
Gregor Mendel is known as the "Father of modern Genetics". He found many facts about heredity when he studied thousands of pea plants.

I'm not entirely sure on this one... But I think it's 1. cell division helps animals repair old cells..
