C. exocytosis (I have to use 20 characters to respond and "answer it well". Exo means out/outside and exocytosis is an active transport system where a cell uses energy to transport material, like protein or waste, from inside a cell to the outside.)
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:
its a noun
the semipermeable membrane surrounding the cytoplasm of a cell.
Answer No 1:
Cell can be described as the basic unit of organization of all living things. All living things, whether prokaryotes or eukararyotes, will be made up of a cell or different cells. Prokaryotes are one- celled whereas eukaryotes are made up of many cells.
Answer No 2:
A group of tissues which work together make up an organ whereas, group of organs which work together will make up an organ system.
For example, the organs such as the heart, the lungs, the liver, the kidneys etc are made up of different tissues which work together so that these organs can perform their prescribed functions.
Answer No 3:
Different organs work together in an organ system so that an organ system can perform its functions.
For example, in the circulatory system, the heart, capillaries, veins, arteries work together so that they can provide transport blood.
Answer No 4:
Different tissues perform different functions. Different tissues will work together to make organs of an organ system. These organs will work together to make the organ system perform its function.
Answer No 5:
Every organ of an organ system has a vital role to play for the proper functioning of the organ system. Malfunction of any of the organs will result in the functions being not performed. For example, the function of the heart is to pump blood. If the heart stops working then the circulatory system will not be able to transport oxygen.
