Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? Depolarization has to do with surfaces becoming more negative or positive and reaches a certain point called a threshold. When the threshold is reached‚ an action potential is initiated. 2. What was the threshold voltage in Activity 1? The threshold voltage in Activity 1 was 3.0. 3. What was the effect of increasing the voltage? How does this change correlate to changes

Lab Assessment Questions & Answers 1. What is the significance of creating Groups and adding Users to Groups? Explain. It is important to put user in groups because it is easier manager there permissions. Instead of assigning permissions to a new user every time someone is hired‚ you would just add them to the groups they need. 2. Given a scenario where there are five (5) database administrators that may periodically need access to a given system. Discuss a concept to better manage these administrators’

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate
