Answer:
first question: 3. osmosis is a kind of diffusion that involves the movement of water
2nd question: 1. it allows carbon dioxide to move in and out of the cell
Explanation:
Remember, diffusion is when molecules move from an area of HIGH concentration to an area of LOW concentration. Therefore, in this example the molecules on the outside, where the concentration is high, will diffuse to the inside of the circle, where the concentration is low.
The name of the nerve that passes posterior to the elbow ,specifically between the medial epicondyle and olecranon process is called the ulnar nerve.
Answer: all of these exercise modes, but less likely with low intensity endurance training.
Explanation: exercise increases respiration requirement and therefore oxygen requirement. Energy stores (glycogen) are used first but with then the body needs to maintain energy production at an increased level. There is a limit to how quickly energy can be supplied from respiration and additional energy is generated anaerobically with the by product being lactic acid. An ‘oxygen debt’ is incurred because normal homeostasis requires the metabolism of lactic acid and energy for repair of any cellular damage, requiring oxygen consumption above what is required for normal resting metabolism. It is possible in elite athletes that during low intensity training they may be able to operate aerobically for an extended period.
Answer;
-Mitochondria
Explanation;
-Mitochondria is a cell organelle where ATP is generated, it act as a powerhouse of the cell. ATP is generated through the process of cellular respiration.
-Cellular respiration is the process by which cells break down nutrients such as glucose to release energy in form of ATP, which is used by the cells to drive cellular processes such as growth and transport. The process involves three stages ; namely, glycolysis, citric acid cycle and electron transport chain, when oxygen is present.
