"Nucleotides with a single ring structure"
I tackled that part, also providing explanation to the point you focused on.
Explanation:
Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.
Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.
The statement environmental influences begin at birth and continue throughout life is definitely False.
<h3>What do you mean by Environment?</h3>
Anything which is present in the surrounding of an organism is called its environment. The environment is surrounded by abiotic and biotic factors.
Environmental influences will not remain the same throughout life. If a human is affected by a natural disease, it will definitely be cured with medications. Environmental influences sometimes behave as genetic diseases, which stay long or sometimes endless.
Therefore, the statement environmental influences begin at birth and continue throughout life is definitely False.
