1. Proteins are made from subunits called amino acids. There are 20 different amino acids which are responsible for the variation of proteins. Those amino acids are linked together by peptide bonds and form polypeptide chains. According to the polypeptide structure, there are 4 levels in protein structure as primary structure, secondary structure, tertiary structure and quaternary structure.
2. Starch is a type of carbohydrate. Hence, the subunits of starch are sugar molecules which are called as glucose. The elements of glucose are C,H,O. By linking glucose units with 1-4 alpha glycosidic bonds, the polysaccharide chain is formed. Hence, starch is also a polysaccharide<span>.

3. DNA is made from subunits called nucleotides. Nucleotides consist of deoxyribose, phosphate group and nitrogenous base.
There are two types of nitrogenous base as purines and pyrimidines. Adenine (A) and guanine (G) are purines and
thymine (T) and cytosine (C) can be seen as pyrimidines. Those nucleotides are linked together by sugar phosphate bonds which are formed between 5' phosphate group and 3' -OH group<span>.</span><span>

Bladder cancer, because of a mutation or damaged genes in the DNA of the cells.
Answer:F=enzyme
Explanation: becasue it is the aswer
Answer:
Silent mutations is when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
Explanation:
Answer:
The correct option is C.
Explanation:
Osmosis is a good example of passive transport. In this transport across the cell membrane without any input of cellular energy movement of atomic substance occurs.
Osmosis is defined as the movement of water across the selectively permeable cell membrane from the high osmotic pressure potential towards the area of low osmotic pressure potential. Some examples of osmosis are skin soaking up water, plants receiving water, and when exposed to freshwater red blood cells swelling up.
