Answer:
Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.
Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.
Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.
Explanation:
Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.
Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.
d. what is the effect of paper bags on the environment?
Answer:
natural disasters,emigration and scarcity of food
Explanation: natural disasters: this affect population where by organisms leave there area or habitat for another area due to unfavorable conditions eg. flood, bush fire, storms, earthquake etc. and can also lead to death.
Emigration:this is when organisms leave an area for another either in search of food, breeding purpose this reduses population where by organisms may never return.
scarcity of food:this occur when there is insufficiency or no food in an area which makes organisms leave their habitat for another in search of food and might even lead to death.
2. cell wall is around plant cells, regulates transport in and out of cell.
3.a plant cell does not have lysosomes whereas an animal cell does
Food crops are sometimes affected, but the severity really depends on how much fertilizer the farmer adds to the crops because it replaces the nutrience that have washed away.
