I know that they use it for sensing danger
Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles<u> because of the accumulation of lactic acid due to inadequate oxygen in their system.</u> When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

Person Y does not feel any burning sensation in their muscles <u>because oxygen is adequate in their system and they do not need to respire anaerobically.</u> <em>Person X exercise regime must have been more rigorous than that of person Y.</em>
NN, ss, mm because homo means the same so if they are the same they are homozygous.
Answer:
b. they are both performed by plants.
Explanation:
Photosynthesis is the process of transforming light energy into chemical energy by green plants. During the process, the plants make use of solar energy in order to convert carbon dioxide and water into carbohydrates. And also releases oxygen into the atmosphere. Photosynthesis is called primary production because the food produced by the process makes the base of most ecosystem food chains. It stores energy at the bottom level of the food chain.
All animals are dependent on photosynthesis because animals depend on glucose as their energy source, but they are incapable of producing it on their own, so they must depend on plants in order to get glucose.
And also the oxygen that animals breathe is released during photosynthesis.
Cellular respiration:
It is the process through which living cells degrade glucose molecules, releasing energy, and store it as ATP molecules. Overall, glucose and oxygen react to generate carbon dioxide and water in this three-stage process.
