The thing that would mostly make the results of the experiment invalid would be the students themselves. No one is built the same, and the exact same food can have very different effects on different people.
<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
organisms taking food from living host are parasite while taking food from dead matter are saprophytes..</em>
Answer:
The correct answer is- founder effect
Explanation:
Founder effect occurs when a small number of individual isolates from the majority of the population by natural calamity or any other region. These isolated individuals show less genetic diversity than the larger population because they are less in numbers.
Therefore founder effect makes a small group of individuals isolate from a bigger population and make them occupy a different habitat. So a founder population can go on a newly developed island and start reproducing there.
A founder population over time converts into a new species because of reproductive isolation from the main population. So the evolution of life on the island of Hawaii should have been most strongly influenced by founder effect.
The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
Answer:
Part A: Influenza virus
Part B: Influenza is a public health issue because it is one of the leading cause of death all over the world. Proper vaccination against the illness can prevent death and other serious illness due to this virus.

Part D: Efforts are underway to create a cheap and effective vaccine against this virus. The National Vaccine Program Office is responsible for coordinating and ensuring collaboration among federal agencies involved in vaccine and immunization activities.
Part E: A vaccine against this virus will prevent people from facing the effects of this virus. Also, compulsorily vaccinations against this virus will ensure a major reduction in deaths caused by it.
