The correct answer is: a tourniquet.
The tourniquets are tight straps around an arm or leg and tightened to stop bleeding, used to control arterial and venous blood flow. In the past, tourniquet are used to control bleeding during amputations. Now, a tourniquet is used in surgeries to block arterial blood flow following and to minimize blood loss.
Answer:
a) both processes first break down glucose into pyruvic acid
Explanation:
Cellular respiration is the process through which cells of living organisms derive their energy. Cellular respiration can be carried out with oxygen (aerobic) or without oxygen (anaerobic). The oxygen actually acts as a final electron acceptor in the last stage of aerobic respiration process (ETC).
Cellular respiration starts with GLYCOLYSIS, which is the process whereby glucose is broken down to pyruvic acid. Glycolysis occurs in the cytoplasm and does not require oxygen to occur. In a complete respiration, the step progresses into the Kreb's cycle and Oxidative phosphorylation, which occurs in the mitochondria.
Hence, GLYCOLYSIS (break down of glucose to pyruvic acid) is a common process to both aerobic and anaerobic.
Hope this helps I had this question on my paper and got it right
Answer: B. collar cells and amoebocytes
The collar cells have a funnel like collar and a flagellum. Collar cells whip their flagella to make water go through the sponge. Then the water brings nutrients and oxygen, while while also taking out waste and carbon dioxide.
Amoebocytes first deliver nutrients from choanocytes to the other cells, giving rise to eggs. Then they bring phagocytized sperm from choanocytes to eggs.
