<h2><em>
Streptococcus pyogenes</em></h2>
Explanation:
On looking through the microscope we will see purple, spherical-shaped organisms arranged in chainlike formations.
The reasons are:
- Streptococcus pyrogenes is a gram positive bacteria and hence it will take up Gram's stain and appear purple in color.
- Streptococci are colonial bacteria that are spherical in structure arranged in chain like formations.

A. T-A-C-G-A-T
A and T pair together, and G and C pair together. There are no U’s because U’s are in RNA, not DNA.
Answer:
Niacin (Ans. A)
Explanation:
Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.
Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.
These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.
The answer to this question would be: 2^23
When the gene is dividing, the chromosome pair, which was made by 2 single chromosome, will be divided into two single haploid chromosomes. That means there is two kind of possibilities for each chromosome. If there are 23 chromosomes then it will be 2^23 possibilities
