Answer:
The correct option is;
A, B, and C, only
Explanation:
The amino group is the functional group of the form CH-NH₂ consisting of single bonds formed between hydrogen atoms, aryl groups, alkyl groups or two or more of such groups combined together bonded with a nitrogen atom. An amine is an organic compound that has an amino group in its composition or structure
Therefore, the amino group can be found in the molecules of A, B, and C only.
<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms :
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.
Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>
The answer to your question would be space. The sun's light travles through space. but if you clap, you can't hear it.
Microtubules are tiny, hollow, bead-like tubular structures that help cells maintain their shape. Along with microfilaments and intermediate filaments, they form the cytoskeleton of the cell, as well as participate in a variety of motor functions for the cell.
Ribosomes, because both prokaryotes and eukaryotes have ribosomes to make proteins.
