The nuclear membrane is often thought of as a protective structure, separating the genetic material from the rest of the cell. however, mrna must be able to leave the nucleus to travel to a ribosome. how is this accomplished?
a. mrna attaches to a transport protein and exits through a gated channel.
b. mrna is small enough to diffuse across the lipid bilayer of the nuclear membrane.
c. mrna exits through nuclear pore complexes.
d. mrna is enclosed in vesicles which fuse with the membrane and exit.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
