Answer:
The correct answer is the last option, that is, multigene families are similar or identical genes, whose evolution took place by gene duplication.
Explanation:
A member of a family of the associated proteins encrypted by an array of identical genes is known as a multigene family. It is considered that the origination of the multigene families has resulted due to the variation and duplication of a single ancestral gene.
The multigene families make the assembly of the proteins comparatively quickly, as it assists in the simultaneous transcription of various genes at distinct locations.
This is a scientific question because you could conduct an experiment to test the theory.
Answer:
In the Sympathetic Nervous System PNS subdivision in which nerve injury would be the most dangerous for life.
Explanation:
In the Sympathetic Nervous System PNS subdivision in which nerve injury would be the most dangerous for life.
It is important for survival to fight or respond to flight because it controls the physiological reaction to a risk or danger and this flight and flight response is activated by sympathetic nervous system. This system is a part of automatic nervous system and operated by various interconnected neuron
