Answer:
d. nicotinamide adenine dinucleotide (NAD) and derivatives.
Explanation:
a. amino acids (such as cysteine and proline)
b. vitamins (such as riboflavin and thiamine)
c. Adenosine triphosphate
d. nicotinamide adenine dinucleotide (NAD) and derivatives.
<em>Growth factors of bacteria are compounds that are important for the growth of bacteria but which cannot be synthesized by the bacteria themselves. Without these compounds, the growth of bacteria would be limited or they will not even grow at all.</em>
These compounds which are usually organic in nature include purine and pyrimidine nucleotides, vitamins, amino acids, and hormone-like peptides.
From the options, only option d does not fall among the growth factors required by bacteria.
Hence, the correct option is d.

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>

The correct answer I would say it's c it actually has 12 but around 15 depending on what type and brand
The differences between a plant and algae are:
- lack of vascular tissue in algae.
- different types of chlorophyll used in chloroplasts
