A change is a single nitrogenous base can cause a mutation called which of the following A. evolutionary mutation
B. point mutation
C. micromutation
D. zoomatic mutation

The correct answer is - option B. point mutation.

Explanation:

A genetic mutation occurs due to a change in a single nucleotide base, either inserted or deleted from the genetic material (DNA or RNA) sequence, which represents the mutation called a point mutation.

It can take place by the substitution of the single nucleotide sequence in DNA or RNA in the genome of the organism, it is also known as substitution mutation.

Sickle cell anemia is an example of the point mutation that takes place due to a change in a single nucleotide sequence.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
