With scissors or a scalpel, cut along the side of one arm the entire length of the arm from the tip of the arm to the point where the arm attaches to the central disk.

Which blood vessel, the mesentery artery, the hepatic portal vein, or the hepatic vein contains the most glucose after eating? Use the picture below and the models in the lab to identify the following components of the nephron.

Flux rates describe the addition/removal of energy to/from the various parts of the system and the rate of transfer of energy between the components of the system. In the Excel file you can change the initial values (X) of any or all of the state variables and coefficients (P), and control the length of time simulated.

In order to find something to compare this number with, we need to calculate the degrees of freedom, or the number of different comparisons that can be made within the table.

What kinds of data do you think would be useful in determining the cause of this UME event based on the condition of the dolphins? Some scientists remembered that there was a similar case in 1987–1988, as described in Morbilliviral Disease in Atlantic Bottlenose Dolphins and in Dolphin Strandings.

The hypothesis where the data support your idea is called the alternate hypothesis, abbreviated H a . Note: this is a different type of hypothesis, used to fit specifically into statistical tests.

As you peel this piece of carapace away, it may be necessary to reach underneath with the point of a scissors or needle to brush away and detach any tissue from the interior of the animal that is attached to the carapace. Brush all of the gills to the side and then carefully cut the membrane (epidermis) that covers the internal organs.

Some species are oviparous—they lay eggs that hatch outside the mother’s body; some are ovoviviparous—the eggs are retained within the body and young are born alive; and a few are viviparous—they receive some nourishment via a placenta that develops from the yolk sac of the egg.
