Answer:
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.
Answer:
b. excretes excess albumen molecules
Explanation:
Albumin is a type of globular protein which is present in the blood plasma and it is about 75-78% of the plasma. It is a small protein soluble in water. Its main role is to maintain the oncotic pressure of blood by binding to water fatty acids, cations and hormones. When albumin level falls and no longer sustain sufficient colloid osmotic pressure, then to counterbalance hydrostatic pressure, swelling of body (edema) develops. The urinaray does not excretes excess albumen molecules from the blood.
Answer:
Extension
Explanation:
Extension refers to a physical position that increases the angle between the bones of the limb at a joint. It is a posterior movement for joints that move backward or forward such as the neck and it happens when muscles contract and bones move the joint from a bent position to a straight position.
Extension of the a joint is limited to 180 degrees. if it goes beyond that, it becomes hyperextension.
Hyperextension is an extreme version of extension. it is an excessive joint movement in which the angle formed by the bones of a particular joint is straightened beyond its normal range of motion. this type of movement is unhealthy and may increase chances of dislocation.
Nondisjunction
DNA replication duplicates every strand of DNA so that there
are two copies of every chromosome. These (attached) copies, called sister chromatids,
undergo two rounds of chromosomal divisions ( Meiosis I and II). A total of
four haploid cells are now present. Homologous chromosomes or sister chromatids
are pulled apart in a process called disjunction. However, chromosomes may at
times fail to separate properly. This is called nondisjunction.
Answer:
DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.
