As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen; when the weightlifter’s muscle cells are not able to take in enough oxygen to make very much ATP, as he competes in the event.
Explanation:
Anaerobic respiration takes place when there is too low or no oxygen to perform aerobic respiration. This transfers the energy to the cells from glucose. It produces energy very quickly along with lactic acid and other waste products.
Anaerobic respiration is highly useful when short bursts of energy are required very quickly to energize the muscles to perform high intensity activities like wrestling, weightlifting, intense short workouts, etc.
Lactic acid fermentation causes the muscles to burn out when high intense short burst physical activities are performed.
Answer:
That would be the sun, because of its gravitational pull its what pulled the other planets closer, then making our solar system. However, the sun was formed after the solar nebula, but thats not an option, so the next thing made was the sun. I hope this helps you! :D
Answer:
Anytime matter is in motion it has kinetic energy.The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Kinda like a pyramid. The bottom is wide, many sources of energy (plant life) that take nutrients combine them with water use the bonding of the suns rays and convert that to matter. This matter is then consumed by animals (grazers and browsers), who in turn are fed upon by predators. With man as the top predator.
Take a few seeds from wire-grass. Wire-grass grows in many natural communities, it is eaten by rodents and birds, like Quail. Quail are eaten by snakes, who are eaten by hawks, bobcats, and raccoons.
every time the meal is transferred from one critter to the next, energy is expended in the chase (heat) and capture, and energy is always being used for the animals to survive day by day.
