Write a small paragraph explaining your choice of experimental procedure to measure nerve impulse speed. You will have to come up with one but you cannot use a scalpel or an electrode (or any other complex equipment that you didn't have in class) only things that you had in class. Explain briefly the rationale of the procedure and with a friend (or many friends depending on your protocol) perform the procedure at least 23 times providing me with an average of your measurements along with the associated standard deviation. If you have no idea what those are please review the video here. You can also ask me or any of your other science professors or scientifically minded friends.

Which is the correct order in the scientific process? ask a question ® form a hypothesis ® make an observation ask a question ® make an observation ® form a hypothesis make an observation ® form a hypothesis ® ask a question make an observation ® ask a question ® form a hypothesis

Astudent from one of the research labs is having trouble preparing a slide for examination and photographing. the bacterial slide that he has brought to you was prepared using a commercially purchased stain. he has asked for your in determining what he is doing wrong so that he can change the lab protocols and continue on with his project. after examining the slide under oil immersion, you determine that no bacteria are present even though the student is able to show you the culture he used to make that slide that has visible growth in the liquid medium. which of the following statements does not explain the fact that there are no bacteria present on the student’s slide? by not allowing a glass slide to completely air dry before heat fixation, the flame will cause the surrounding water to boil and this will damage the bacterial cell. overheating during the fixation step boiled the water within the bacterial cells and resulted in the cells bursting. insufficient heating of the slide did not drive out the thin layer of water and this resulted in minimal bonding between the bacteria and the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide.

What does it mean for an allele to be dominant?
