Answer:

A.) White dwarfs are formed from the collapse of low mass stars, less than about 10 time the mass of the Sun. ... On the other hand, neutron stars are formed in the catastrophic collapse of the core of a massive star.

B. According to the HR diagram, a star with the surface temperature of 10,000 Kelvin is a star with a B spectral type. Moreover, if the star were on the main sequence, then it would have a luminosity nearly 100 times more than that of the sun.

C. After leaving the main sequence, Vega will become a class-M red giant and shed much of its mass, finally becoming a white dwarf. At present, Vega has more than twice the mass of the Sun and its bolometric luminosity is about 40 times the Sun's.

Answer:

<u>The correct answer is that our student accumulated lactic acid.</u>

Explanation:

<u>What is acid lactic and where it comes from?</u> It comes from the breakdown of glucose when there is no oxygen present (glycolytic metabolism), that is, in an anaerobic exercise such as running or cycling at high speed, like the case of our student, where there is a high intensity and a very short duration.

<u>What happen then?  </u>When we keep doing exercise with high intensity an exercise, lactic acid will begin to accumulate by not giving the body time to remove it.

<u>How can we avoid lactic acid?</u> With training, there is no more. Based on training, the body deploys adaptive mechanism that causes lactic acid not to accumulate so quickly and if it begins to do so, the muscle supports it more effectively.
