Answer:
This happens because viruses mutate and vary according to the environment they face. That is why different strains occur and appear every day, which must be updated in the vaccines, in order to have immunity up to date and keep up with the viral mutation without making us sick.
Explanation:
Viruses are acellular structures that do not have their own metabolism or replication method, it is because they must dominate and invade the human body so that its DNA or RNA is coupled to the human and this uses the human machinery to be able to replicate.
On the other hand, as infections occur and viruses appear, they can associate with bacteria forming bacteriophages, they can mutate within an organism that is infected by more than one viral infection and they can even adopt retrovirus mechanisms, which day by day. These new viruses are called as new strains, which evolve and will have to be coupled with vaccines.
Vaccines are a method of natural ACTIVE immunity, that is, part of the virus is inoculated, so that it generates the formation of a specific antibody in the body.

Answer:
people have unique, genetically influenced reactions to particular experiences
Explanation:
According to the gene-environment interaction, genetic makeup of an individual determines its potential response to particular sets of conditions. Interaction of environment with genes conditions required to bring about those potential responses.
For example, genes of an individual predispose the ability to withstand stressful conditions and the presence of motivating surroundings enables the individuals to achieve their maximum potential.
If the same individuals were brought up under the conditions of deprivation, the resistance level would not have reached its optimum value. Hence, genes determine the limits on abilities and environment determines how much of these abilities are retrieved.
Answer:
The correct answer is C. Burning fuel releases carbon monoxide and other chemicals into air.
Explanation:
The burning of flue realeases carbon monooxide which is highly reactive.Carbon monoxide binds with hemoglobin resulting in the formation of carboxy hemoglobin.
Carbon monoxide interacts binds high affinity to hemoglobin than oxygen.The binding of carbon monoxide to hemoglobin displaces the oxygen from hemoglobin thus reducing the affinity of the later for oxygen.
When carbon monoxide binds to hemoblobin, then less hemoglobin is available to bind and transport oxygen to the peripheral tissues of the body..An exposure to carbon monoxide for long period of time can cause death.
