The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Answer:
Which statement best describes the components of nucleic acids?
They are made up of nitrogenous bases, sugars, and phosphates.
Explanation:
<span>One important area of DNA research is that of genetics and medical research. Due to our discovery of DNA, our ability to actually diagnose diseases early on has been vastly improved. In addition, we have been able to better assess a person's genetic susceptibility to specific diseases. In doing so, we have also paved the pathway to formulate brand new drugs to treat these diseases. In fact, drugs can essentially be custom made to complement a person's personal biochemistry and genetic makeup. For those diseases that were previously considered lethal and where treatment was either non-existent or largely unsuccessful, the discovery of DNA has essentially led to breakthrough drugs and treatments for patients with serious illnesses.</span>
