By binding to DNA it triggers the transcription of a specific gene.

B. Mycoplasmas
The protein from which hook and filaments of flagella are composed of, is
B. flagellin
A cluster of polar flagella is called
A. lophotrichous
The cooci which mostly occur in single or pairs are
B. Diplococci
Flagella move the cell by
C. spinning like a propeller
Explanation:
The process that happens in the retina is absorption of
Light by Photo pigments. In the eyes
light enters through the aperture called the iris. It go through the lens of
the eye (a clear, doubly convex construct that is attached to muscles that make
it fatter or thinner in order to focus the light) and hits the retina. In the
retina there are rods and cones. The rods sense degrees of light and dark
(black and white) and the cones sense colors.
Answer: Option B) allosteric activation
Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation
Explanation:
Some enzymes have more than one active site. The other site(s) is called allosteric site.
In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.
ATP + H2O ---> ADP + Pi + free energy
