Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve. Involuntary reflex reaction to exposure or inexposure to light—in low light conditions a dilated pupil lets more light into the eye. :)
Answer:
Restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule
Explanation:
Hope it helps
Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
The answer is <span>potato.
Potato is a stem tuber while carrot, beetroot, and radish are true root crops and not tubers.

Tuber is a structure that provides nutrients for the next season regrowth. It is specialised for asexual reproduction. Potato is a stem tuber, for example. In one growing season, the tuber is produced and used to perennate the plant. In the autumn, when the plant structure above-ground dies, the tuber survives underground over the winter. When spring comes, tuber regenerates new shoots thanks to nutrients stored. On the other hand, true root crops (carrot, beetroot, radish) are modified roots to store energy but they are not specialised for asexual reproduction.
