You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.

How is scientific writing different from the style of writing that you learned in ENG 111?  (Select all that are correct.)   Group of answer choices a. Scientific writing is concise, written in 3rd person, and uses past tense. b. Science writing uses lots of colorful language to describe visual reactions to the experiment. c. Science writing uses lots of personal pronouns (e.g., I, me, we, you, your, our) to show ownership of the results and personal attention to directions. d.Science writing assumes the reader already knows how to do the experiment that is the subject of your paper. e.Science writing may include references that are from peer reviewed sources.
