Q. Explain the sequence of steps by which an action potential propagates without loss. Illustrate a diagram of an axon indicating the site where the peak action-potential currents flow across the membrane. Show the lines of current flow to unexcited parts of the cable. Elucidate how these local currents cause the action potential to propagate.
Sketch the Na+ and K+ currents which flow during an action potential. Look up how gNa and gK vary with time during the action potential -- given in the class notes -- and then recall that INa =gNa(V - VNa) , IK = gK(V-VK), and that the voltage V(t) is varying according to the action-potential shape. You could do this qualitatively, but justify your reply. A common mistake is to confuse the currents that flow throughout the action potential the voltage-clamp currents flow in response to a depolarizing pulse.
In addition to the synthesis of RNAs, ribonucleotides are involved in other critical cellular functions.
The molecular data=based tree creates a group called "Ecdysozoa". Explain what is "ecdysis" in this group?
If the experimental animals in the chamber were engaged in physical activity (such as running in a wheel), how do you think this would change results of the metabolism experiment. What changes would you expect to see in the fluid levels of manometer.
If a cell with 2n=4 chromosomes failed to separate homologous chromosome pairs correctly during meiois, so that one pair went to one daughter cell and other cell received no copy,
Imagine you have engineered a set of genes, each encoding a protein with a pair of conflicting signal sequences that specify different compartments. If the genes were expressed in a cell, predict which signal would win out for the following combin..
So we have Algae, Fungi, Lichens, Mosses, Ferns, Gymnosperms, Angiosperms (monocot) and Angiosperms (dicot).
Suppose you're interested in determining the long-term effect of 5-hour energy drink on fruit flies by studying mutants. Would you undertake a forward genetic screen or a reverse genetic screen?
Would you describe your study area as an area of high or low biodiversity?
Your paper must provide APA-formatted references for all resources used and adhere to APA style and format. APA style headers will be expected for the three subsections of biological basis, research, and public health application. Use subheaders a..
Discuss the stages in the production of an RBC and describe how each stage differs from the previous one.
Why would it be difficult for just one person to see what a population of birds is doing and what are the obstacles
