Answer:
The similarities in the way barchan and hooked spit forms are:
First, they are formed from sediment or sand movement.
Second, this movement makes them have a peculiar curved form that provides them their major characteristic.
Explanation:
First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.
Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
Human activities have altered various natural environments around the planet. Various lands are now fields where only one farm crop is cultivated, is an example of monoculture farming.
An agricultural method of growing or producing a single plant, crop, or a livestock species, breed, or a variety in a field of the farming system at a time is known as a monoculture. Hence, the correct answer is option D, that is, monoculture.
The answer is C. This is because nucleotide elongation involves the addition of a nucleotide to the 3 prime carbon of the previous nucleotide carbon ring. This involves a dehydration reaction between the phosphate group on the 5 prime carbon of the last nucleotide to the hydroxyl group of the 3 prime carbon of the previous nucleotide.
