Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)

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 C: serious illness and death, mainly among children and elderly
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.
When a stimulus is being detected, this stimulus is being sent to the brain through the sensory neuron, going to the spinal cord then to the brain. The brain then interprets these stimuli, and responds to it using the motor neurons. These are the neurons that are responsible in our actions depending on the stimuli we are exposed to. Hope this helps.
