Oxygen is released from the mitochondria as a product of cellular respiration.

A. Is oxygen diffuses from the lungs into capillaries, blood becomes deoxygenated.
B. Carbon dioxide diffuses from the alveoli into surrounding capillaries.
C. In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells.
D. Oxygen diffuses from large blood vessels into the body's cells

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
