Lab Practicum‚ Micro 200‚ study guide When you did your hand wash experiment‚ you decided a variable to test‚ say‚ hot vs cold water‚ you called this variable an “experimental variable” since it was the variable you were testing experimentally. In order to get meaningful data‚ you need to keep other things the same‚ for example the washing time had to be the same for both‚ you called the washing time a _Control_______ variable. Through the semester‚ you have used two bacteria that produce

end of the week. My first task was to peer review the writing assignment for Unit 2. Therefore‚ that was what I did first and this did not take long. I was surprised because most of the students did not get the answers correct‚ or they left it incomplete. When I saw the answers‚ I knew I had gotten three of them wrong and I was so furious because I was unsure of the answers that I produced at first‚ and I had changed them several times. One student got 2/7‚ and the other two got 3/7. This make me

Prior to injecting the neurotoxin‚ Tubocurare‚ inside the gastrocnemius muscle‚ a control was established. The baseline was maintained approximately at 20 grams. The control used the maximum voltage of 0.75 volts for the stimulus input. As a result‚ the tension produced 68.13 grams of force. The moment Tubocurare was infused into the gastrocnemius muscle‚ the muscle tension dropped to 47.7 grams of force. Data was recorded for 10 minutes‚ and as predicted prior to the experiment‚ the tension trend

workload doubles. The muscles can hold a higher workload if they originally have a higher threshold of stimulation with no workload at all. 2. Why would a muscle’s threshold of stimulation change as its Workload changes? A muscle’s threshold of stimulation changes as its workload changes because the muscle needs more stimulation and more power to contract. 3. Which muscles were able to contract under the greatest loads? What does this suggest about the role these muscles play in frog movement
