Phagocytosis is a complex process that can be affected by many different things. State a hypothesis as to something that you believe might affect phagocytosis in Tetrahymena. Be specific as to how you believe it might affect phagocytosis
What is your independent variable?
dependent variable?
Negative control?
Homework Answers
Hypothesis = The rate of phagocytosis increases with the increase in the concentration of copper ions
Independent variable - Concentration of copper
Dependent variable - Rate of phagocytosis
Negative control - A mixture or setup containing a high concentration of copper.

We make many decisions throughout our day based on probability. What is an example of something from your daily life that you choose based on how likely it will happen? How would the probability need to change for you to make a different decision? 1. Hypothesis testing is based on the idea that if there is enough of a difference between your experimental sample and the comparison distribution, you can see the research supports your hypothesis. Describe an experiment in...

EXERCISE 2: TESTABLE OBSERVATIONS Below are several observations that can inform a testable hypothesis. For each of the following observations: Determine if the observation is qualitative or quantitative. Write a hypothesis and a null hypothesis. What would be your experimental approach? What are the dependent and independent variables? What are your controls- both positive and negative? How will you collect your data? How will you present your data (e.g., chart, graph)? How will you analyze your data? OBSERVATIONS 1. Fresh-baked...
