Answer:
The organisms must have a known cellular composition, in addition, it is necessary that all their metabolism and molecular functioning be analyzed and understood by the scientists who will carry out the research project. In this way, it will be possible to see real changes that could happen in the organism that was inoculated with the parasitic amoeba. These modifications will be responsible for pointing out whether the amoeba has the capacity to infect aggressively or not.
In addition, model organisms must be easy to control and reproduce if the study requires data on reproduction and offspring.
Step-by-step explanation:
Model organisms are non-human living organisms used for scientific studies. They are extremely relevant when it is necessary to conduct studies on very large living beings and are difficult to analyze and control, such as human beings.
Generally, microorganisms and mice are used as model organisms in several studies, but plants, rabbits, monkeys, among others, can also be used.
