3 points A scientist is investigating the effects of a new medication on blood
pressure. Different groups of patients will receive different amounts of the
medication over the course of a month. Their blood pressure will be
measured every day. A control group will not receive any of the
medication. What is wrong with this experiment? *
The experiment does not have a dependent variable.
The control group should also receive the medication.
It will be impossible for scientists to repeat this experiment because no two study
groups are the same.
It is impossible to correlate a medication with blood pressure because there are so
many variables that cannot be controlled.

How does the author's purpose in this passage differ from an author writing about her personal struggle living with asthma?

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
