Tutoring and Test Taking Experiment
You want to see how much additional tutoring helps Biology students. You choose 10 students at random from a Biology class and assign them 2 hours of extra tutoring each week. You then give all students a test and determine the average scores for the tutoring and non-tutoring groups.
1. Name the Independent and Dependent Variables from the experiment above.
2. Name two good Control Variables you would keep track of in this experiment.
3. This experiment already has a Negative Control Experiment built into it. What was the Negative Control Experiment?
4. Create a hypothesis for this experiment.

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
