Which of the following correctly describes the image below? A single hydrogen atom bonded to a central carbon atom. An amino gro
snow_lady [41]

According to the way you defined the image, the right answer is C. Amino Acid.

The amino acids found in proteins all have the same basic structure: they are oriented around a central carbon atom, the α-carbon, on which the carboxyl group (-COOH) is articulated, the amino group (-NH2). ), a hydrogen atom (-H) and a lateral group (denoted -R). It is the nature of this lateral group (also called side chain) which differentiates the amino acids between them.

The central α-carbon is therefore asymmetrical in all cases except that of glycine (because glycine has a hydrogen instead of a side chain). This means that it is possible to have two different conformations of the same amino acid conformations that can not be interconverted without breaking and reassembling covalent bonds. These conformations L and D are designated. Although both can be synthesized in the same chemical reaction, only the L-form is used in the proteins.

maria [59]

exponential growth

Explanation:

The organisms that are not native of a particular environment but are exposed to live in that particular environment are invasive species. Usually invasive species do not prove useful to the new area and prove harmful to the environment as well. There are some species of organisms that have been accidently introduced to new environment and have been accidently proven to be beneficial. Zebra mussels, being the native to Black Sea when arrived to North America flourished there.
