Romashka [77]

Answer:

D. 3:1

Explanation:

Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.

However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

A star goes throgh different stages until it gets completely formed. The first stage is nebula. <em>Nebulae</em><em> are _</em><u><em>dust</em></u><u><em> and </em></u><u><em>gas</em></u><em>_ where _</em><u><em> </em></u><u><em>stars</em></u><em>_ can form.</em>

<h3>Star Cycle</h3>

The star cycle is the sequence of changes that a star undergoes throughout its existence.

The evolutive stages of a star differ between an average star and a giant star.

However, the first stages of the cycle are shared by all of them.

<h3>What are the common stages in stars cycles? </h3>

  • Nebula

Stars are born from the nebula that is the<u> dust </u><u>and</u><u> gas particles </u>condensation due to gravity effect in the interstellar clouds

  • Protostar

It is a more advanced level of condensation.

  • Main sequence.

Equilibrium between gravity and nuclear fusion helps the star keep stable as long as the fuel lasts.

Hence, according to this resumed introduction to stars cycles, we may say that<em>  </em>

<em>Nebulae</em><em> are _</em><u><em>dust</em></u><u><em> and </em></u><u><em>gas</em></u><em>_ where _</em><u><em> </em></u><u><em>stars</em></u><em>_ can form.</em>
