Answer:
The cell wall
Explanation:
The cell wall exists to protect the cell, maintain its shape and regulate water uptake. The cell wall is much thicker than the cell membrane, providing an extra layer of protection. In plants, the cell wall is made of fibres of the polysaccharide cellulose, which is a structural carbohydrate.
This gives organisms such as plants much more structure - e.g. they can stand upright without the need for bones. However, they lack the same flexibility that animal cells have.
Limestone is the correct answer
The four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).
These bases form specific pairs (A with T, and G with C).
<h3>What is DNA nucleotides?</h3>
Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate.
They serve as monomeric units of the nucleic acid polymers –
- Deoxyribonucleic acid
- Ribonucleic acid,
So therefore, the four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).

Answer: Small intestines
Explanation: Digestion of carbohydrates begins in the mouth mechanically and through salivary amylase. It passes down to the stomach by parastalsis, digested further and goes to the small intestines where their absorption begins. Carbohydrates are a source of glucose, that most organs use as their primary energy source. Indigestible carbohydrates and fibers travels down to the large intestines where they are digested by bacteria or eliminated as waste through the anus.
The small intestines consist of microvilli that increase surface area for maximum nutrient absorption. Carbohydrates are absorbed by the small intestines via the jejunum, taken to the blood stream then transported to the liver where glycolysis and most metabolic pathways take place, for energy production.
The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
