True.
Shivering is a bodily function in response to cold in warm blooded animals/human. When the core body temperature drops shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements creating warmth by expending energy.

Hi there! This question is a bit confusing. 
 Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge. 
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
 Your answer would be "Secondary cells are rechargable" 
Have a great rest of your day!

Explanation:
Granite is a type of grainy (medium-coarse) igneous rock. These are formed from quartz, alkali feldspar and trace minerals along with plagioclase. Rocks like quartz, form a crystal from magma or as a precipitate near hydrothermal vents. 
A type of intrusive igneous rock, granite is formed from its constituents when it molten rock cooled. Larger mineral crystals are associated with slower cooling over time.
