We see the moon because the sun's light reflects off it. So the phases change depending on how much the sun reflects of it. The moon circles around the Earth so at certain times there will be a full moon and at certain times a new moon and everything in between.
Answer:
I just answered this same question for my Biology class hope this helps :)
Explanation:
A hydrogen bond is when positive and negative hydrogen forms together; this explains why cohesion sticks molecules together . Because of cohesion, the water molecules stick together and form a surface; this property is responsible for surface tension. Adhesion is the ability for water to stick to other substances; this helps with capillary action. Hydrogen bonding also explains why water's boiling point is higher than some liquid . With this, water has a high specific heat; this is because the water takes a lot of energy to raise (or lower) the temperature. Once again, hydrogen bonding is essential to another property. This property causes water to expand and to have a low density when frozen.
Answer :
D) Plants
Explanation :
A producer is a plant or organism that produces it own food. Plants go through a process of Photosynthesis Which makes its own food.
Step 1 - All the reactants collect in the Chloroplast
Step 2 - Light energy from the sun drives the reactants to make a chemical reaction.
Step 3 - The products of the chemical reaction including Glucose the plants food and Oxygen, which is released into the air and which living organisms breathe.
Your Welcome! Good Luck!
