Answer:
the second one
Explanation:
it has very few abiotic factors
Answer:
A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.
Explanation:
<em>At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes</em>. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.
One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.
The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase
<em>Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes. </em>
The correct option is A.
Pancreatic Mucinous Cystadenocarcinoma with Splenic Abscess and Fistula between the Splenic Abscess and the Colon: A Rare Case
What is Mucinous Cystadenocarcinoma of the pancreas?
Rare malignancies include mucinous cystadenocarcinomas (MCAC) of the pancreas. Surgical resection is typically associated with a positive prognosis when it is restricted to the pancreas alone. However, there is little information on the potential benefits of palliative chemotherapy for diseases that cannot be surgically removed.
The right subphrenic abscess, splenic abscess, and an abscess in the front of the tail of the pancreas of unknown origin were all diagnosed in the 65-year-old woman who was admitted on January 8, 2003, due to fever that had persisted for five months. A normal pancreas was visible on the CT scan with low-density lesions that represented abscesses in the spleen and intraperitoneal cavity (front of the pancreas' tail and umbilical area). Her symptoms improved following the drainage of the intraperitoneal abscess in the umbilical region and the splenic abscess under US guidance. Splenectomy was performed in order to confirm the existence of a fistula connecting the splenic abscess to the splenic flexure of the colon (spleno colonic fistula) and stricture of the transverse colon.
It is uncommon to have a splenic abscess together with pancreatic cancer.

B, 4,2 and seven I hope this helps!!
Chemotherapy is a process of intense treatment for cancer. It includes one or more anti-cancer drugs. However, most people become sick after they go through with chemotherapy. This can last for days or longer. Hopefully, nobody gets cancer and has to go through this procedure.
