Hello, I'm Angie and I'll be assisting you. I would appreciate it if you could thank me
Plants grow from areas of cells called meristem, which are the only places on the plant where new cells can be made.
On some kinds of plants, the meristem is arranged so that when the tip of a root - which contains the root apical meristem, from which new growth is initiated. If it is cut off, new roots are signaled to start growing from the side, an area called the lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new adventitious roots.
Roots of plants keeps on growing even after the evacuation of their tips it is on the grounds that the roots have meristematic cells which have the ability to grow. Meristematic cells are the totipotent cells which have the ability to form any kind of plant cell. These cells experience continuous division and create the new tip.
As auxin (plant growth hormone) is also available in tips of roots. When we cut it at that point no more extension will happen. Auxin here will induce now lateral growth of roots; just sidelong growth happens which will increment in flat development this procedure is utilized by gardeners.
I would like to say B but im not sure, it seems the most logical

Answer:
A mutation in the N-terminal region may alter protein stability
Explanation:
Transport proteins are proteins capable of transporting substances through biological membranes. These proteins are located within cellular membranes where they form channels that allow the movement of substances between the internal and external sides of the membrane. The N-terminus is the first region in the protein that emerges from the ribosome during its synthesis. This region is usually composed of signal peptides consisting of about 30 amino acids required for protein delivery. Moreover, the N-terminal region is also important because it dictates protein degradation by peptidases. Consequently, mutations in the N-terminal region of transport proteins can alter the properties of these proteins, i.e., either by modifying protein stability or by altering protein signaling.
