Question: Which of the following would be considered a source of error in an experiment
A) only three house flies were collected for an experiment
B) A beaker is knocked over and the contents are spilled on the floor
C) the data do not support the hypothesis
D) An incorrect average is calculated for the control group
Answer:
"Only three house flies were collected for an experiment
" would be considered as a source of error in an experiment.
Explanation:
Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.

The nervous system is responsible for the control and communication among the body.
The thermosphere is a layer of the earth's atmosphere directly above the mesosphere and below the exosphere. It extends 56 miles to about 621 miles above the earth.
It is in the thermosphere that auroras are seen. An aurora is luminous atmospheric phenomenon appearing as streamers or bands of light sometimes visible in the night sky in northern or southern regions of the earth. It is thought to be caused by charged particles from the sun entering the earth's magnetic field and stimulating molecules in the atmosphere.
It is a compound made of twenty-four total atoms
After six to eight days, the adaptive immune response begins and is specific to the infection. It involves two types of white blood cells: T cells (cellular response) and B cells (antibody response).
Generic reaction to ANY infection; Innate immune response cells generate interferons1 and other substances (cytokines); Interferons prevent virus reproduction; Phase 2 is triggered; Innate immune response.
The body's defense against viral infections
At this stage, infection in phases one and two can be stopped.
1. The early signs of infection, such as fever and muscular pains, are brought on by interferons and cytokines.
2. The adaptive response could not be stimulated right away if the innate reaction is "weaker" in some individuals (such as the elderly or those with underlying health issues).
