. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.

This contains 100% correct material for UMUC Biology 103 LAB01. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the questions answered:

 

 

Exercise 1: Data Interpretation  (2 pts each)

1. What patterns do you observe based on the information in Table 4?

No fish are present when the dissolved oxygen is zero. When there is more dissolved oxygen in the water, more fish are present. However, the number of fish tends to drop or level off when the dissolved oxygen is higher than 12 ppm.

 

2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.

Possible Hypotheses:

….

identify at least three key differences between their approach and COVIDsafe app

8.1. It seems malaria is much worse than COVID-19. In order to monitor and control the spread of malaria, how should the data from mobile phone networks be used to conduct predictive analytics and control the disease spread? Justify your answer, please. 8.2. In your answer to the question 1, please list at least three major concerns or issues with your proposed approach

8.3. Australia is using COVIDsafe mobile app to help find close contacts of COVID-19 cases (Brief introduction on COVIDsafe app is available at https://www.health.gov.au/resources/apps-and-tools/covidsafe-app). In comparison to how Bangladesh controls the spread of malaria, please identify at least three key differences between their approach and COVIDsafe app. (4.5 marks)

Experiment 1: Enzymes in Food

This experiment tests for the presence of amylase in food by using Iodine-Potassium Iodide, IKI. IKI is a color indicator used to detect starch. This indicator turns dark purple or black in color when in the presence of starch. Therefore, if the IKI solution turns to a dark purple or black color….
