Why is oxygen necessary for muscle contraction?

1 answer:

5 0

During period of time of heavy lifting or extreme muscleman air , sinew do not get oxygen quickly enough to provide vitality . In these face , the body must convert a substance called pyruvate into a substance called lactate, reports Scientific American language . Too much reliance on lactate can confidential information to high levels of acidulousness in muscles and disruption of metabolites. When muscles have adequate oxygen, a person performs aerobic physical exercise for extended periods without trouble. Production of lactate only generates enough energy for one to three moment of anaerobic activity.

Fantom [35]

Answer:

D. The offspring of multi-cellular organisms tend to be identical to the parent.

Explanation:

The offspring of multi-cellular organisms which reproduce through sexual mode can never be identical to the parents because of crossing over which is a phenomenon which occurs during meiosis. All the individuals which have sexual dimorphism and reproduce sexually have germ cells in their gonads. Meiosis is a type of cell division which occurs only in germ cells not in somatic cells. During meiosis the genetic material from both the parents is exchanged leading to new combinations of genes as a result of which offspring is neither 100% identical to father nor to the mother. Offspring displays traits which are a combination of both the parents thereby showing variability.

Which of the following is an example of diffraction?

makkiz [27]

Answer:

You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction

Explanation:

Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.

Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
