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.
Answer:
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.
Upwelling is the process that brings deeper water to the surface, and its major significance is that it brings nutrient -rich deep water to the nutrient-deprived surface, stimulating primary production
Explanation:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot.
