Let's think first: Bone provides protection for soft tissues and internal organs. For the heart is the chief organ of the body and rules it. Bone provides protection for the heart.... So the answer is [(G)]


What do many plants do to respond to the shorter days in fall?
Options:
- (A) go through a resting period
- (B) changing the phase
- (C) Release energy
- (D) Generating heat
- (E) produce more pollen
- (F) colder and wetter
- (G) grow taller
- (H) make more chlorophyll
--
Let's think first: Many plants respond to the days growing shorter in the fall by going dormant. Plants can be divided at any time, although the dormant or rest period is best. Many plants respond to the days growing shorter in the fall by going through a rest period.... So the answer is [(A)]


What kind of plants produce pollen?
