Answer:
Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have <u>carbon</u>, <u>hydrogen</u>, and <u>oxygen</u> in a 1:2:1 ratio.
Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.
Make an example...
Short carbohydrate chains are called <u>oligosaccharides</u> and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of <u>glucose</u> and one molecule of <u>fructose</u> joined together.

Explanation:
There are only three types of endocytosis namely; phagocytosis, pinocytosis and receptor-mediated endocytosis
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
