When testing a hypothesis, scientists use repeated trials and replication to make sure that they get the same answer each time, and that it isn't just a lucky guess the first time. They need be sure that the answer to their hypothesis is 100% the same every time.
Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.
It reproduces cells to work for all systems
Answer: True
Explanation:
The dual energy x-ray absorptimetry is a technique that is used for measuring the bone mineral density. This technique utilizes the two X-ray beams with different levels of energy. The soft tissues are subtracted in this procedure and the beam is absorbed by the bone. This technique is useful for diagnosis of osteoporosis, to check and diagnose the infected, fractured and healing bones.
Fluid retention is a condition in which excess fluid due to capillary leakage or any other reason fills up inside the circulatory system, body tissues and cavities. The following symptoms will appear:
Discolored skin, aches and tenderness in the limbs, stiffness in joints and weight gain.
The retained excess fluid may react with the X-ray beam hence, will interfere in the process of diagnosis. Thus caution should be taken for such individuals.
