Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…

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.

sure your internet connection is working well. Interrupted service can be used as a reason for a retake, only have one attempt. There are no retakes. ot click the "Back" button on your web browser it will kick you out of the exam. e: Make sure to answer all questions. If you close the exam early with answering all questions in your exam. wers that you answered will count as your completed exam and all questions not answered will be marked Question 1 Which of the following best explains why soap and water remove grease? O Soap molecules are large polymers that absorb grease O Soap molecules are ionic and attracted to grease Soap molecules are nonpolar and dissolve in grease O Soap molecules have ionic "heads" that dissolve in water and nonpolar "tails" that dissolve in water O Soap molecules have ionic "heads" that dissolve in grease and nonpolar "tails" that dissolve in water.

Trial [I0:] [HSO: ] Time Rate [HSO3 ]/time 1 49 25 3 16.9 Table-2 Find the concentrations of [IO3] and [HSO3] and enter into the table. Divide the concentration of HSO3 with the time in seconds to get the rate. Volume is assumed to be additive in this experiment. Thus, the total volume of all the solutins is assumed to be 20.0 mL. This introduces a small error that can be considered insignicant. The concentrations of IO; and HSO, (after mixing but before the reaction begins) can be calculated using the relationship: Mailute Vdilute= Mcone Vcone. A sample calculation is shown below for the concentration of IO, in Trial 1: Mailute to be calculated Vdilue 20.0 mL 0.020 M x 2.0 mL Mcone 0.020M V conc 2.0 mL %3D diluted [IO, ] = = 0.0020 M IO, %3D 20.0 mL Similarly, the concentration of HSO; in Trial 1 is calculated thus: 0.010 M x 2.0 mL diluted [HSO, ] =0.0010 M HSO, 20.0 mL

Answer question number 7 on the attached document

For a field ecology project, you count the number of individuals of different ages found in a population during a single time period. There are 100 newborns, 40 1-year-olds, 15 2-year-olds, 5 3-year-olds, and 0 4-year-olds. Use these data to fill in the Nx, Sx, and Ix columns of a static life table.

if you could please help! i submitted this previously and was told that it looks incomplete. the questions are complete and there is no additional information to upload with the questions. again there are 6 questions and i have done a majority of them. i really just need help with question 2 and 3, however, if you could look at my answers for the questions i did and tell me if they are correct i will gladly rate you! thank you so much. I apologize if it is small, i made the font smaller to fit everything on one picture

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.
