Answer:

1. The most appropriate answer would be an option C.  

A point mutation refers to the mutation or change that occurs at only one or a few nucleotides of the DNA.

Usually, a single nucleotide is substituted with the wrong nucleotide due to which only a single codon is affected.

However, it can cause frame shift mutation if insertion or deletion of nucleotide takes place.

In contrast, in chromosomal mutation long segment of DNA is involved. It may involve one or more genes. It mainly includes insertion, deletion, translocation, and inversion.

In addition, chromosomal mutation can cause change in the number or sets of chromosomes such as poliploidy, aneoploidy et cetera

2. The correct answer would be C. A point mutation

A point mutation refers to the mutation or change that occurs at only one or a few nucleotides of the DNA.

Which statement about neural reflex arcs is incorrect? Which statement about neural reflex arcs is incorrect? Their function is
olchik [2.2K]

Answer:

The incorrect statement is that the neural reflex arc becomes slow by the hormones involved.

Explanation:

A neural pathway that controls a reflex is known as a reflex arc. In a reflex arc, the sensory neuron transmits a signal to the interneuron and stimulates it. The interneuron then transmits or passes the signal to the next neuron, that is, a motor neuron. The motor neuron associates with the interneurons in the spinal cord, which transmits messages from the CNS to the body. Thus, a reflex arc comprises the elements, that is, the receptor, integrating center, and the effector. Their main activity is to protect the body from external events.
