Answer:
The right atria
Explanation:
The heart is the core organ of the circulatory system responsible for pumping blood by the contraction of cardiac muscles which is then conveyed to other parts of the body through blood vessels. The heart possesses four chambers of which the two upper ones are called ATRIA and the two lower ones are called VENTRICLE.
Each side of the heart contains one atria and one ventricle. The atria allows blood into the heart while the ventricle allows blood out of the heart. However, during the pumping process, deoxygenated (without oxygen) and oxygenated (with oxygen) blood enters and leaves the heart. The right ATRIA is responsible for receiving deoxygenated blood into the heart while the left ATRIA receives oxygenated blood into the heart.
Answer: Dialysis cleans your blood by passing it through a filter. If you do peritoneal dialysis (PD), the filter is the lining of your abdomen (your peritoneum). If you do hemodialysis, the filter is made of plastic. Your blood is on one side of the filter.
Explanation:Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.
There have been 5 mass extinctions in the history of Earth, the main two are the K-T extinction (75% of the world organisms were killed) and the great paleozoic extinction. Scientists believe a massive meteorite caused the KT extinction but could also have been caused by some traps in India. The paleozoic extinction was believed to be caused by traps in Siberia which effected the temperature and atmospheric conditions of the tune
Answer:
- ATP and NADPH facilitate the reduction of 6 molecules of 3-PGA (formed in carbon fixation)to six molecules of the simple sugar glyceraldehyde 3-phosphate (G3P).
- In the reduction process ADP and NADPH+ are made, when ATP releases energy and loses its terminal phosphate, and NADPH loses energy and a hydrogen atom.
- ADP and NADPH+ return to the light-dependent reactions for re-use.
Explanation:
Sugar biosynthesis in plants, called photosynthesis produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. In chloroplasts, this occurs in the light-dependent and dark reactions. In the light- dependent reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
In the light-independent reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP). Organic molecules are reduced and RuBP is regenerated.
Answer:
E
Explanation:
Turner syndrome females have a phenotype because there are regions of the X chromosome that normally escape inactivation, allowing 2 copies of the gene to be expressed. These regions are called pseudoautosomal regions.
These are inherited in a typically autosomal fashion, permitting crossing over between the X and Y. In Turner syndrome, the lack of second X chromosome means these genes are missing and the phenotypes result from haploinsufficiency
