7. did you identify any prejudices you might have about what traits you find "desirable"? where do
you think these prejudices come from?

Yes, there are certain traits which I find desirable. These traits include having hazel blue eyes, fair skin colour and unattached ear lobes.

In some way or the other, the desire for these traits came from the society in which we live and yes they are a form of prejudice. In the society, having hazel brown eyes is considered to be beautiful. Fair skin colour also marks a form of beauty in society. Unattached ear lobes are common.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
