TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part
of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
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. :)
