The findings presented indicate that the contractile phase, as indicated by the twitch duration, is markedly prolonged by cooling with both direct and indirect stimulation
The findings show that lower temps increase time muscles take to contract.
-
Explain what these graphs are telling us.You can list a few observations or describe it by writing your own figure caption
Graphs express that higher temp lead to higher stimulation. Colder temps lower activity.
-
Animals were stunned by a blow on the head and decapitated
that's not ok
-
n your own words, what is the biologicalquestion that the researchers are asking
Studying the relationship between temperature and muscle twitch.
-
lowering the temperature, by 10 ~ increments

In these experiments weobserved that, before exercise, rats treatedwith CMP/UMP had significantly highermuscle glucose concentrations comparedto nontreated rats
The rats treated with the CMP/UMP had higher muscle glucose concentrations leading them to be able to exercise longer since they have more energy.
-
Explain what the graph in Fig 3 is telling us
Figure 3 - Compares glucose, glycogen, and lactose across the treated and untreated groups of rats in the experiment.
-
Explain what the graph in Fig 1 istelling us
Figure 1 - Compares exhaustion time (in minutes) of non-treated rats (represented in black) to treated rats (represented in white).
-
In your own words, what is the biological question that the researcher is asking
How does CMP and UMP effect animal exercise?
-
What are CMP & UMP
CMP - cytidine monophosphate UMP - uridine monophosphate

nactivation ofsodium channels
significant change in sodium channels

Are there benefits to this difference in activities from low to high concentrations of venom
The low doses can assist in developing anti-venom medicines. The higher doses cause the muscles to twitch more which can be used to increase neuromuscular transmission.
-
what this graph is telling us
Figure 2b - This bar graph compares contracture (percentage of twitch height) to doses of venom measured in micrograms per milliliter.

Although the main effects of scorpion venom arelikely to be due to toxins that affect the opening ofion channels in nerve and muscles
likely due to toxins causing the channels to open more but not fully understood
-
question
The researcher is studying the effects that the O. doriae scorpion's venom has on skeletal muscle.
