Answer:

Nucleic acids are not essential for nutrition

Explanation:

Nucleic acids are a group of biomolecules that functions in the storage and transmission of genetic material within living organisms. DNA is one of the nucleic acids found in nature.

DNA is a storage molecule i.e stores genetic information. It does not store energy, hence, it doesn't serve the purpose of providing nutrient in a cell. Therefore, DNA will not be included on the nutrition labels for strawberries because they are not essential biomolecules for nutrition.

Why does the earth have different layers?
Aliun [14]

Answer:

The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

1. The best answer is Stomata takes in carbon dioxide and release oxygen. Photosynthesis is the process that take place in the leafs of green plants where chlorophyll absorbs sunlight and converts the energy from the sunlight to chemical energy. The process produces simple sugars and oxygen, oxygen is either released to the atmosphere or used in cellular respiration. Simple sugars (glucose) are stored as glycogen and used as an energy reserve. 

2. The statement is true. Water and carbon dioxide are are raw materials of photosynthesis. Water is broken down in the first stage of photosynthesis using sunlight to produce oxygen and hydrogen ions. The second stage of photosynthesis involves carbon dioxide fixation producing simple sugars 
(glucose).

3. The equation that supports the conservation of energy is;
 6CO2 + 6H2O + light = C6H12O6 + 6O2
This is the process of photosynthesis that involves use of carbon dioxide and water to produce glucose and oxygen. 
Six carbon atoms are used to generate another six carbons in glucose, hydrogen atoms and oxygen atoms taken in remain the same in the products.
