Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.
Answer:
Pollution prevention
Explanation:
The water conservation strategy being used when a household uses eco-friendly cleaning products would be <u>pollution prevention</u>.
<em>The cleaning of household materials generally generates wastewaters that somehow find their way into the water cycle of the environment. </em><u><em>Eco-friendly products are those that do not harm the environment in any way </em></u><em>and the use of eco-friendly cleaning products would ensure that the wastewaters generated from cleanings are minimally polluted, effectively conserving the water due to the environment.</em>
