Answer:

There is 97% Chance that the person is infected.

Explanation:

According to the question, the test for the virus has 3% false positive and there is no false negative rate.

Therefore if someone takes the test and gets a positive result, the chances of the person to be infected ( True positive ) is

100 - 3 = 97%

Note: False positive result is a result that indicates that a given condition is present when it is not actually present.

Answer:

The answer is 97%.

Explanation:

The zika virus' 1% incidence rate in the population has no effect over the probability of the patient being infected or not. If the test has a 3% false positive rate that means that if it is positive, the results have a 97% chance of being true. Therefore the chance that the person who took the test and had a positive result being actually infected is 97%.

I hope this answer helps.

kirill [66]

The groups of small cells better than one large cell at moving material in  and out because they have a greater surface-to-volume ratio.

This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.
