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.

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.

Question 7/19 > NEXT A BOOKMARK Almonds are edible seeds that grow on trees. Wild almonds typically have a bitter taste caused by a chemical in the almond. If an organism eats wild almonds, a chemical reaction occurs that releases the bitter taste. However, a genetic mutation in the almond tree can occur that prevents wild almonds from producing the bitter taste. Which statement describes how this type of mutation could affect these wild almond trees? 7 A This mutation could increase the population of wild almond trees. B This mutation could increase the life span of wild almond trees. (c) This mutation could decrease the rate of the production for wild almond tree P Type here to search DELL
