During intense exertion or activity involving the muscles, there arises a need for a sudden short term burst of energy. This need for energy is so demanding that it cannot be satisfied through the normal mechanism whereby energy is supplied through aerobic respiration using oxygen.
Therefore the muscle cells must rely on other mechanisms that do not rely on oxygen to fuel muscle contraction and this is where they resort to anaerobic respiration which uses pyruvate to play the role of oxygen as the final electron acceptor. In the process, pyruvate accepts an electron and is reduced to lactic acid in the muscle tissues.
Kingdom Plantae (all land plants). they are autotrophs which means they produce their own food through photosynthesis.
Answer:
Option 3, Heuristics
Explanation:
Heuristics thinking implies usage of past experiences or judgments or the memory of most relevant and similar incidents to quickly formulate judgments and solutions and make decisions. Such judgments are biased most of the time as they are based on the perseverance of an individual instead of logic and conceptualization of any scenario or incident
Hence, option 3 is correct
Sedimentation<span> is a </span>process<span> in which insoluble particles can be removed from water or any other liquid item.when the impurities in the liquid is stirred and left for a while the impurities in the liquid will gradually settle down at the bottom of the container.This is a </span>process<span> of the settling down of the suspended impurities.</span>
Yes they are caused by erosion of rocks by wind
