When glucose is in the bloodstream, insulin binds to cells. This signals the cell to move glucose transport proteins into the cell
membrane. Glucose then enters the cell using facilitated diffusion.
What happens to glucose in the bloodstream if insulin does NOT bind to the cell membrane?
O A Glucose receives energy from ATP, which allows the glucose to enter the cell.
O B. Glucose is unable to enter the cell, and the glucose remains in the bloodstream.
O c Glucose moves from high concentration outside the cell to low concentration inside the cell.
Oo. Glucose can enter the cell by moving through the channel formed by the empty insulin receptor.

Acar company is testing seatbelts using crash test dummies. the company finds that when cars come to a sudden stop, the crash test dummies' bodies continue to move forward. the seat belt keeps the crash test dummies from hitting the back of the seat in front of them. why do the crash test dummies' bodies continue to move forward even though the car stopped? a. the friction opposing their bodies' movement keeps them in motion. b. the inertia of their bodies keeps them in motion. c. the forward acceleration of the car keeps them in motion. d. the gravity pulling on the car keeps them in motion.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
