<span>D is the correct answer. Coral reefs need sunlight to grow, so they grow best in shallow water (up to 50m deep) as this means sunlight can reach them. They require salt water to grow and warm temperatures of 20 - 32 degrees Celsius.</span>
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
Answer:
The correct answer is 3. sugars
Explanation:
During photosynthesis, the light energy is captured by the chlorophyll and this energy is used in the formation of sugar molecules with the help of water. Oxygen is released as the byproduct of this process.
So the light energy which is captured is stored in the bonds of sugar and when this bond is broken down during oxidation the energy is released and converted into another form which is ATP and this ATP is called the energy currency of the cell. This ATP is used in many metabolic processes. Therefore the correct answer is sugar.
