Answer:
The correct option is A.
A. blocking transmission of impulses from the spinal cord to thalamus
Explanation:
Local anesthetics, like lidocaine and novocaine, reduce the perception of pain by blocking transmission of impulses from the spinal cord to thalamus because local anesthetics they first bind to ion channel in the nerve cell and then inhibit function of the ion channel present in the membrane of nerve cell known as sodium channel. This later cause blockage of nerve impulses at the site where the injection was given from the spinal cord.
Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
