Research major earthquakes on google, or another website. I would go with question 1, Where is your earthquake? I would do the Haiti earthquake where the earthquake is in Haiti. Do more research on Google, because I cannot provide you with a link to an article because Brainly will not allow me to do so. Just research "major earthquakes" in Google and you will be good to go. Hope this helped!
Explanation:
nerves that emerge directly from the brain. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.
Answer: entering a host cell and making copies of itself
Viruses reproduce by infecting a host cell, and making it produce copies of a virus instead of antibodies. This is how viruses double in your body.
Hope it helps you!
<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
