Answer:
<u>Proto-oncogenes</u>
- These genes code for protein that normally promote cell division
- Mutations that increase activity of these genes may lead to cancer
<u>Tumor suppressor genes</u>
- These genes code for protein that normally prevent uncontrolled cell division
- Some products of these genes normally function in repairing damaged DNA
- Mutation that decrease activity of these genes may lead to cancer.
Explanation:
<em>Proto-oncogenes</em> are group of genes that ordinarily help cells develop. At the point when a proto-oncogene mutates or there are such a large number of duplicates of it, it turns into a "terrible" quality that can turn out to be forever turned on or activated when it shouldn't be. At the point when this occurs, the cell becomes wild, which can prompt malignant growth. This terrible quality is called an oncogene.
Tumor suppressor genes are normal gene that hinder cell division, fix DNA missteps, or tell cell when to undergo apoptosis (die). At the point when tumor suppressor gene don't work appropriately or inactivated, cells can develop uncontrollable growth, that ultimately lead to cancer.
A. The scientific theory of evolution is the fundamental concept underlying all of biology.
B. The scientific theory revolution is supported by multiple forms of scientific evidence.
C. Organisms are classified based on their evolutionary history.
D. Natural selection is a primary mechanism leading to evolutionary change.
Answer:
<u>A chemical bond between the phosphate group of one nucleotide and the sugar of a neighboring nucleotide holds the backbone together. Chemical bonds (hydrogen bonds) between the bases that are across from one another hold the two strands of the double helix together.</u>

Answer:
Endocrine and Cardiovascular system
Explanation:
Excess fat intake leads to different health hazards. They affect the body and cause lipids to clog the arteries thereby preventing blood from quickly delivering oxygen to the body parts.
Excess fat intake causes fatty pancreas and decreases its function.
It also causes series of cardiovascular diseases such as heart attack; elevated cholesterol/atherosclerosis,abnormal heart rhythms, hypertension, stroke etc
