Answer: Colon cancer
Explanation:
All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.
Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.
Answer:
Chemotherapy targets the cell directly; biological therapy tries to help the immune system so it will attack the cancer cells.
Explanation:
Both chemotherapy and biological therapy are approaches used in cancer treatment.
Chemotherapy involves the use of aggressive anti-cancer drugs. It targets cancer cells directly with the goal to destroy them.
Biological therapy, also called immunotherapy, is a type of treatment used in battling diseases by activating or suppressing the immune system. It is also used in cancer treatment. Its goal is to boost the immune system and help it fight against cancer.
A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium concentration.
<u>Option: A</u>
<u>Explanation:</u>
Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.
The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.
