Answer:

The right answer is C.

Explanation:

Tautomeric shift type of mutation that happens spontanously by intramolecular proton (hydrogen ion) shift. Guanine and thymine normally found in their keto form but rarely they can be also found in enol forms. Moreover, while adenine or cytosine are normally found in amino forms they can rarely switch into their imino forms by intramolecular proton shift (see figure).

Answer:

plate:  a disk formed in the phragmoplast of a dividing plant cell that eventually forms the middle lamella of the wall between the daughter cells.

plate boundary: Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. ... Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other

earthquake: An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. The strain becomes so great that rocks give way by breaking and sliding along fault planes.

convirgent: In evolutionary biology, convergence pertains to an evolutionary process wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated.

qaws [65]

Answer:

sigma subunit

Explanation:

Sigma subunit of RNA polymerase holoenzyme directs the enzyme towards the consensus sequences present upstream of the transcription start site. Completion of the initiation phase of transcription is followed by dissociation of sigma subunit from the transcription complex.

The protein NusA replaces the sigma subunit. The RNA polymerase leaves the promoter and starts the elongation

Name the structure that increases the surface area of the small intestine in humans.
lutik1710 [3]

The name of the structure that increases the surface area of the small intestine in humans is Villi.

<h3>What are the functions of the small intestine?</h3>

The small intestine performs a key role in the digestion of undigested food which comes through the stomach. It also absorbs all the essential minerals and nutrients from the food and is used by the body.

Villi or microvilli is the structure that increases the surface area of the small intestine for food absorption and adding digestive secretions.

Therefore, the name of the structure that increases the surface area of the small intestine in humans is Villi.
