The answer is a. Nitrogen
<span>A is the correct answer. Diploid cells all contain two sets of chromosomes. Prophase 1 occurs during the first phase of meiosis, a type of cell division, and prophase 2 is the same process, but this time occurring without chromosome reduplication. As a result, there is the original and duplicated cells, which makes two.</span>
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 cell will incorporate solvent - water. When a plant cell contains more solutes than its surrounding environment it means that it is in a hypertonic state, the osmotic gradient will increase and the water will tend to enter the cell augmenting the t<span>urgor pressure inside the cell wall. Ultimately, it will cause water to enter the plant and reach the cell.</span>
