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 answer to this is C.
In the small intestine, it consists of duodenum and ileum in simple. The duodenum is where most food is digested. Enzymes are secreted and they break down complex and insoluble food into simple small soluble molecules.
After digestion, the food will be absorbed into the body in the ileum. The food flow from the ileum into the body cells by diffusion and active transport. Villi is also present in the small intestine to help the absorption process. After absorption, the nutrients would be transferred into the cells that needed.
The rest of the food that is not absorbed is trasferred to the large intestine to re absorb the water. After that, they're feaces and they'll be egested

A benefit of crossing over is that it maintains genetic diversity within a population, allowing for millions of different genetic combinations to be passed from parents to offspring. Genetic variability is very important to the long-term survival of a species
