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.
Answer:
C. Iodine.
The function of thyroid gland is to take iodine from different foods
<span>These are the organelles. These small features in the cell can do tasks as varied as hold the genetic material for the cell (in the nucleus) to holding and carrying out the waste materials that the cells create (the vacuoles).</span>
The answer would be that chromosomes are made out of DNA.
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>
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
It is a more advanced level of condensation.
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>
