Yes, Ca+ channels are not required to fire action potential. As long as the Na+ and K+
channels are open, the neuron will be able to generate an action potential.
No, a neuron cannot transmit a signal across the synapse using neurotransmitters because
1. The purpose of the KOH was to react with the carbon dioxide produced by the peas,
turning the carbon dioxide into a solid.
This caused the water to move into the respirometer because, after the carbon dioxide
becomes a solid, the pressure inside the re

Predicted result (explain why)- White Lawn- Natural lawn growth of the bacteria is
expected because there is no ampicillin restricting the growth of the bacteria and there is
no X-gal to turn it blue.
Actual result: White Lawn
1. Listed below is the process by which peas germinate
2. Because germinating peas consume more oxygen than dry peas, it can be concluded
that germinating peas use more energy than dry peas, in both room temperature and in 10
degrees Celsius. This makes s
At higher temperatures, the molecules of the enzymes would move quicker and have a
higher kinetic energy, which would increase the rate of the enzyme activity.
However, extremely high temperatures that exceed the optimal temperature can denature
In the experiment, the interval with the lowest rate is the 60-120 second interval. The
reaction rate for this interval was -.003; this negative value was probably due to error.
However, the 120-180 second and the 180-360 second intervals both had reactio
The peas would not be able to undergo respiration at this point.
Hypothesis: The enzyme catalase, when working under optimum conditions, noticeably
increases the rate of the hydrogen peroxide decomposition.
Materials: catalase, burette, hydr
Critical value (with significance level = .05) is 7.815.
Since the chi-square value of 71.68 is greater than the critical value of 7.815, we can
reject the null hypothesis.
There is statistically significant evidence that the dihybrid cross does not resul
1. If we first boiled the catalase solution for 10 minutes before doing the lab, the catalase
would denature and would not work catalyze the H2O2 as effectively and quickly.
2. Using boiled human catalase instead of boiled cow catalase would yield differe
