Answer:
2
Explanation:
Oxygen has 6 in the outer shell. So in order to complete its octet it only needs two electrons. Like in the Water molecule, oxygen forms covalent bond with two hydrogen atoms.
Answer:
D
Explanation:
Because it showed me the correct answer
Cellular respiration depends on two chemical reactants; glucose and oxygen. Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis. Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen. Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth.
Answer;
-Hydroxyl groups.
-They have multiple hydroxyl groups.
Explanation;
-Monosaccharides are the simplest form of sugars found in common food items such as honey, cane sugar, fruits. They are the building blocks of other carbohydrates (disaccharides and polysaccharides).
-The are formed by three elements and three elements only: Carbon (C), Hydrogen (H) and Oxygen (O). Monosaccharides have two broad classifications on the basis of the functional group present in them, that is; aldose (contains aldehyde group) and ketose (contains a keto group).
-Monosaccharides contain multiple hydroxyl groups, and are responsible for the hydrophillic property of monosaccharides allowing them to dissolve in water easily.
