Answer:
A and T occur in similar proportions.
G and C occur in similar proportions.
Explanation:
There are four nitrogenous bases that form integral part of DNA, these are Adenine (A), Guanine (G), Thymine (T) and Cytosine (C). Due to specific base pairing between these bases, (Adenine is always linked to Thymine through two double bonds and Cytosine is always linked to Guanine through three double bonds), it is estimated that A and T occur in similar proportions. while G and C occur in similar proportions. <em>This was proposed by Chargiff for the first time and now it is considered to be as Chargiff rule. </em>You can see chart in attached image to know that how equal the ratios are found experimentally in different living organisms.

Answer:
Lightly pigmented people tend to be at higher risk of vitamin D deficiency
Explanation:
BACKGROUND KNOWLEDGE:
Human skin is the largest organ of the body which makes boundary line between environment and internal conditions. Human skin cell produces pigment called melanin when ever it is subjected to Sun. More the melanin pigment produced more will be the skin darkens. Ultraviolet (UV) radiations also come from Sun and responsible for more pigmentation.
ANSWER EXPLANATION:
According to the question darkly pigmentation only occurs when their is high level of UV radiations. High level of UV radiations are also responsible for Vitamin D production.
People with lightly pigmented means that there environment has low level of UV radiations which are the requirement of Vitamin D production. Hence due to low UV radiations peoples with light pigmentation's are also be at higher risk of vitamin D deficiency
he cell's DNA is first transcribed in a temporary copy (mRNA), which is then translated into the amino acid sequence of a protein. amino acids – twenty molecules that are the building blocks of proteins.
Answer:
75% one eye, 25% two eyes (or 3:1 one eye: two eye)
Explanation:
The cross between the two trolls are shown in the attached punnett square
Ee x Ee gives 3 genotypes: EE, Ee, and ee
at a ratio of :1 EE: 2 Ee: 1 ee
Ee and EE are both one eye genotypes, so the <em>phenotype </em>is 3:1 one eye to two eye.
