Option A, Exfoliation, is the right answer.

The effects of fluctuating temperature on the rocks that causes the rock to break apart from the massive rock are known as Physical weathering. Freeze-thaw (occurs due to the water leakage into clefts, freezing and extending, and finally separating the rock) and Exfoliation (occurs as clefts form equal to the surface of the land a result of the conversion in pressure through uplift and abrasion) are the two chief varieties of physical weathering.

Thus, Exfoliation is the separation of consecutive thin crusts from huge rock such as basalt or granite.

sergejj [24]

Answer:

There is no short answer.

Explanation:

The primary difference between the periodic and perpetual inventory system is that the perpetual system keeps track of things from the start to finish continuously while the periodic system divides it into periods and keeps the records at the end of every set period of time.

I hope this answer helps.

Find the prokaryotic promoter sequences; Draw boxes around them, Circle the start codon. Then transcribe the following DNA seque
Degger [83]

Explanation:

The transcription is a process which transcribe the DNA into a molecule which could be read by the machinery to translate it into the proteins and that molecule is known as the mRNA molecule.

1.The mRNA molecule is transcribed by an enzyme called RNA polymerase which transcribe DNA in 5'to 3'direction that is DNA strand will be 3' to 5'direction therefore the strand with 3' to 5' will act as template strand.

2. The RNA polymerase binds at promoter region and there are two sequences in prokaryotes at -35 end which is TTGACA and at -10 end which is TATAAT.

3. The translation begins after the start codon which is AUG therefore proteins will be synthesized after AUG.

In the given question, both promoter sequence are present in the 5'to 3'strand

There are two start codon thus two polypeptides will be synthesized.
