The right answer is C.

Sulfur purple bacteria (also called sulfooxidative phototrophic bacteria) are part of the family of photosynthetic bacteria with green sulfur bacteria and cyanobacteria. However, unlike cyanobacteria, purple bacteria such as sulfurous green bacteria do not produce oxygen during photosynthesis. In the sulfur oxidation-reduction process, these bacteria oxidize sulfide (H2SO3) to elemental sulfur (S).

Peroxidase is a protein. What is this protein’s function, and how did it get its name?.
Olin [163]

Answer:

Most peroxidases are ferric heme proteins; one notable exception being the glutathione peroxidase, which is a selenium-containing enzyme. They are present in virtually all living species.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is
Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp
