The electroencephalogram (EEG) is a form of test which is used to measure the electrical activity in the brain. The activity is characterized by means of brain waves and is measured by frequency, amplitude, and the polarity of the brain waves. The alpha waves are low-frequency (8-13Hz) waves that are recorded when an individual is in a drowsy state.

Question

You have returned to college to become a phylogeneticist. One of the first things you wish to do is determine how mammals, birds, and reptiles are related. Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees. Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.

true or false, the reason geckos can walk on walls is hydrogen bonding between their foot pads and the moisture on the wall.

Biology laboratory problem Please help. thank you You have 20 ul of DNA solution and 6X DNA loading buffer solution. You have to mix your DNA solution and DNA loading buffer before load DNA in an agarose gel. The concentration of the DNA loading buffer must be 1X in the DNA and DNA-loading buffer mixture after you mix them. For that, I will add _____ ul of 6X loading buffer to the 20 ul DNA solution.
