Problem: - Winter comes and the animal finds a place to hibernate - Over a period of days, the animal's heart rate and breathing rate drop slowly - Electrical activity in the brain almost ceases completely, though some areas remain active - The animal has entered hibernation mode - What might be the first step of the process?

A: The animal eats large quantities of food that will be stored as fat

Problem: - These pores are called stomata - Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves - Chlorophyll absorbs the sun's energy - It is this energy that is used to split water molecules into hydrogen and oxygen - Oxygen is released from the leaves into the atmosphere - Hydrogen and carbon dioxide are used to form glucose or food for plants. What might be the first step of the process?

A: Carbon dioxide from the air passes through small pores (holes) in the leaves

Problem: - Steam is produced under pressure - Flows into a turbine - The turbine spins - Creates electricity. What might be the first step of the process?

A: Coal is burned in a boiler

Problem: - ITS LAID ON A LEAF OR PLANT - THE EGG HATCHES - THE LARVA COMES OUT(CATERPILLAR) - IT BEGINS TO EAT ON THE LEAF THAT IS WAS BORN ON - CONTINUES TO EAT TO GROW QUICKLY - AFTER ITS GROWN TO FULL LENGHT IT FORMS INTO A PUPA - UNDERGOES METAMORPHOSIS TO BECOME BUTTERFLY - AFTER HE BUTTERFLY IS FOMED IT PUMPS BLOOD INTO ITS WINGS TO GAIN STRENGHT TO BE ABLE TO FLY - TH EBUTTERLFY IS FIANLLY ABLE TO FLY AWAY. What might be the first step of the process?

A:
EGG
