Both B and C

________ tissue, a type of connective tissue, functions to minimize friction between joints in the skeletal system.

Cartilage or Muscle

A dehydration(synthesis) reaction occurs during __________ in order to build larger molecules from smaller subunits

Condensation

In ________ molecules are transported across the cell membrane by a carrier protien.

Facilitated Diffusion

A _________ junctions allows cells within a tissue to exchange materials in order to preform a common function

Gap

Explain why medical professionals need to understand the extracellular enviroment of their patients when preparing and injecting intravenous(IV) fluids.

If they put too much of the IV fluids your blood cells would burst because they would be hypotonic( too much fluid/water). Or if they don't put enough then your blood cells would shrink because they would be hypertonic(not enough fluid/water).
