Answer:
1. Lipids
2. Carbohydrate
3. Lipids
4. Carbohydrate
5. Lipids
6. Lipids
7. Carbohydrate
Explanation:
Lipids and carbohydrates are two of the four major biological molecules (the other two being proteins and nucleic acids). They (lipids and carbohydrates) are both long chains composed of elements: carbon (C), hydrogen (H) and oxygen (O).
Lipids called triglycerides are majorly made up of building block fatty acids (long hydrocarbon chains with carboxylic acid) and glycerol ( an hydrocarbon made up of three hydroxyll groups).
Carbohydrates, on the other hand, are made up of long chains of carbon, hydrogen and oxygen with aldehyde or ketone functional group. They are composed of monosaccharide building blocks (also called simple sugars) with general formula CH20(n).
Based on the structural composition of lipids and carbohydrates, structures 1,3,5 and 6 are lipids while 2, 4 and 7 are carbohydrates.
The force of gravity affects all objects on Earth by pulling them towards the centre. The Earth is close to spherical in shape as this is the geometry gravity prefers. Without gravity, objects would be floating in space. The atmosphere would not exist as the air particles would have no force pulling them towards the planet. Gravity means when you throw something up, most of the time it will come down. It is a force, which causes objects to accelerate when they fall.
