IF A PLANT CELL IS PLACED INTO A HYPERTONIC SOLUTION...
.......Answer.........volume inside the plasma membrane shrinks and
pulls away from the cell wall; plasmolysis
IF A PLANT CELL IS PLACED INTO A HYPOTONIC SOLUTION...
.......Answer.........a small amount of water may enter the cell, but
the cel wall prevents major expansion
PHAGOCYTOSIS .......Answer.........involves the endocytosis of
solid materials (large vesicles)
RECEPTOR - MEDIATED ENDOCYTOSIS .......Answer.........requires
the binding of particles to specific receptors on the external face
of plasma membrane
,age 2 of 42
PINOCYTOSIS (CELL DRINKING) .......Answer.........endocytosis of
liquid materials (small vesicles)
The "HD gene" (huntingtin) was discovered in 1993. Did this
discovery lead to a complete understanding of the cause of HD?
.......Answer.........no, because the functions of normal and altered
Huntingtin proteins are still unclear
Dr. Huntington used observations on phenotypes in families to
prove that the illness he studied was a genetic disease
.......Answer.........False
Pedigree analysis involves making diagrams that can be used to
infer hereditary processes. .......Answer.........True

WHAT IS THE ORDER OF MOVEMENT FOR A NEWLY MADE
PROTEIN THROUGH THE ENDOMEMBRANE SYSTEM?
