1. myosin is plentiful in muscle cells, but is not found at all in lens cells.
lens cells contain large amounts of crystallins, which are not found in
muscle cells. why do some proteins appear in one type of cell but not in
another?
during differentiation, certain genes are added to cells to produce proteins that
enable specific functions.
differentiated cells produce all proteins but destroy the proteins they do not
use.
differentiated cells release unused proteins into the blood for other cells to
use.
during differentiation, certain genes are activated to produce proteins that
enable specific functions.

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
