The answer is: They are water soluble vitamins.

Water-soluble vitamins dissolve in water, which means these vitamins and nutrients dissolve quickly in the body. Unlike fat-soluble vitamins, water-soluble vitamins are carried to the body’s tissues, but the body cannot store them. Any excess amounts of water-soluble vitamins simply pass through the body.

The answer is: They are water soluble vitamins and therefore not stored in the body.

While fat-soluble vitamin could be stored inside the fat cells, water soluble vitamin couldn't. The kidney will filtrate the blood and all of the molecule below a certain size will be dumped if there is not mechanism to reabsorb it. Since the vitamin is soluble in water, it will be easily filtrated too. There is no pump to reabsorb the vitamin, so it will be removed with the urine.

What is the third type of variation in Mendel's theory?
Nikitich [7]
The three most important Mendel law is the law of dominance, law of segregation, and law of independent assortment. The law of dominance is when a trait is more recived or more dominate than other trait. For example a flower, if a flower is red most of the flowers will be red, but one will be white. The white flower has a recessive trait. The law of segregation is when a offspring randomly receive one allele of every trait from each parent. The law of independent assortment states that just because you received one allele doesn't mean another dominate allele will be passed also.

What is the function of telomerase? What is the function of telomerase? Telomerase is an enzyme that increases the length of lin
sashaice [31]

Answer:

The correct answer will be option-Telomerase is an enzyme that increases the length of linear chromosome ends

Explanation:

Telomerase is a reverse transcriptase enzyme which adds the length of DNA by adding the guanine-rich repetitive sequences called telomeres at 3' end of the DNA.

The enzyme not only adds the telomere but also maintain its length in the organism.  The telomerase activity possesses several roles one of which is that it protects the end of the DNA from DNA damage and neighbouring chromosomes.

Since telomerase adds the repetitive sequences at the end and thus increases the length of the DNA thus is the correct answer.

Where does the sound of thunder come from??
Elis [28]
Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning.
