Answer:
The correct option is B.
Explanation:
Dual innervation is a biochemical process by which an organ receives two different types of stimulation simultaneously. The principal function of dual innervation is to maintain the homeostatic balance of the body system. Dual innervation is brought about by two different systems, the sympathetic and the parasympathetic nerve systems. Although the actions of these two nerve systems are opposites to one another, they work together to bring balance to the body system. Without dual innervation the homeostatic system of the body can not be maintained.
Answer:
Option (d).
Explanation:
Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.
Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.
Thus, the correct answer is option (d).
