What type of transportation is this scenario? a red blood cell made up of 9% potassium has a sodium potassium channel that moves the potassium ions across the cell membrane. if the surrounding plasma which contains 5% potassium and the cell is only permeable the solvent. osmosis active transport diffusion facilitated diffusion?

As the concentration of potassium is higher inside the cell, no energy should be required to transport it outside, but the involvement of the channels for this transport signifies the involvement of a facilitated diffusion of the potassium ions, down the concentration gradient, with the help of the channel proteins. 

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
