Organic compound is generally any chemical compound that contains carbon. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Study of the properties and synthesis of organic compounds is the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonates and cyanides), along with a handful of other exceptions (e.g., carbon dioxide), are not classified as organic compounds and are considered inorganic. No consensus exists among chemists on precisely which carbon-containing compounds are excluded, making the definition of an organic compound elusive.[1]Although organic compounds only make up a small percentage of the Earth's crust, they are of central importance because all known life is based on organic compounds. Most synthetically produced organic compounds are ultimately derived from petrochemicalsconsisting mainly of hydrocarbons.
Answer:
The correct answer is -
1. Adenine - 10%
2. A-T and C-G always in DNA.
Explanation:
1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.
So, Cytosine = 40%, Guanine= 40%
total = 80%
therefore, the A and thymine would be - 100 - 80 = 20
A+T = 20
A= 10, and, T = 10%
2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.
The answer is oropharynx. The oropharynx is the center some portion of the pharynx (throat) behind the mouth. It incorporates the accompanying: Back 33% of the tongue. A delicate sense of taste. Side and back dividers of the throat.
<span>I think girls are more likely to experience puberty at a younger age like there menstrual cycle starting younger than the normal average age when dealing with family stress. I also believe it may cause boys and girls to get body order from sweating more from puberty when dealing with family stress.</span>
