		glial cells
		bacteria
		extracellular matrix

2)

In experiment 2, you stared at a blue triangle for 30 seconds and then looked at a white piece of paper. What happened and why?

		you saw a blue triangle because your brain can't register color changes that quickly
		you saw a different colored triange, because your brain can't register color changes that quickly
		you saw a different colored triangle, because your cone cells have become fatigued after repeated stimulation
		you saw a blue triangle because your brain was still focused on the original blue triangle

3)

In experiment 3, why did the room temperature water feel warm when your finger was cold and then it felt cold when your finger was warm?

		thermoreceptors can only detect slight temperature differences
		thermoreceptors do not register temperature, merely heat flow
		the thermoreceptors in your finger are not very accurate, as they are not critical to the function of the body
		thermoreceptors are only good at detecting painful (or potentially harmful) temperatures and therefore are not accurate for room temperature

4)

Which of the following is not categorized as connective tissue?                  

		blood
		bone
		adipose
		skeletal muscle
		all of the above are examples of connective tissue

Answer 1

1.)
Glial cells

2.)
you saw a different colored triangle, because your cone cells have become fatigued after repeated stimulation
If you stare at a red object and forthwith look into a white space afterwards, you may see Associate in Nursing aftersensation that's a similar size and form, however it's blue-green, or cyan, in color. this is often as a result of your eyes use the red, inexperienced and blue cone cells to understand white light-weight, however as a result of the red cone cells worn out, you are doing not experience. you're briefly left seeing with solely your inexperienced and blue cone cells.
