The correct answer is blood type.
The blood type of the individual in determined by the genes they inherit from their parents, it has no environmental influence.
The skin color is determined by the genes, but the main reason behind the presence of the skin color is melanin pigments. The melanin pigments present in the skin can increase to a significant level, if the exposure to sun is more. So, it is not alone determined by the genes.
The athletic ability and the muscle mass are acquired by exercising and physical training. It has a little genetic influence, it is mainly determined by the amount of exercise a person do.
Answer: Tau
Explanation:
NFTs or neurofibrillary tangles are insoluble twisted fibers. The tangles are abnormal accumulation that collect inside neurons. Their presence is also found in other diseases such as tauopathies. Statins have been shown to reduce neurofibrillary tangles in mouse models. Lithium has been shown to decrease the phosphorylation of tau. The tau protein is primary maker Alzheimer's disease.
Answer:
10%
Explanation:
Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C
Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}
These equal concentration equals 100% in totality i.e. A+G+C+T= 100%
Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.
Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.
That is, 10% Guanine, 10% Cytosine.
