The post-eradication era is a period of history for which there has been no precedent whatsoever in terms of a zero base of immunity. Cessation of immunization will eventually create a population susceptible to widespread infection in the event of accidental or intentional reintroduction or re-emergence of the eradicated virus. Thus, even after immunization ceases, vaccine production must continue.
However, many currently available vaccines may not be appropriate for continued post-eradication vaccine production or reinstatement. Vaccines must be continually improved and ongoing vaccination research maintained. Other potentially useful antiviral strategies—antivirals, prophylaxis, and probiotics—must also be considered as means to strengthen the immune system and serve as adjuvant or prophylactic therapies.
In the case of polio, for example, it remains to be determined which vaccine (oral polio vaccine [OPV] or inactivated polio vaccine [IPV]), or variant thereof, should be produced in the post-eradication, post-vaccination era. A detailed plan for vaccine production will require more information on OPV-derived viral persistence and transmission, as well as continuing dialogue between public health and research communities in order to ensure that appropriate vaccination research continues.
Answer:
Axon is responsible for the quick transmission of the nerve impulse.
Explanation:
<em>B. Has the same allele on both chromosomes in a chromosome pair. </em>
<u>Here is why:</u>
Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.
There can be two types of homozygous alleles.
~
<em>Homozygous Dominant</em>: BB
<em>Homozygous Recessive</em>: bb
<u>Notice in both of these they were the same alleles.</u>
~
<em>Heterozygous</em>: Bb
<u>Notice how both are different alleles.</u>

Below I have attached a diagram of a Punnett square I have made.
On the left is a homozygous recessive allele pair.
On the top is a heterozygous allele pair.
The correct answer is all of the above
