Answer:
Sugar can’t enter cells directly
Explanation:
So when blood sugar level rises, cells in the pancreas signal for the release of insulin into the bloodstream. The insulin attaches to the sugars and signals cells to let it enter with the attached sugar. Insulin is known as the key that unlocks cells.

Answer:
Expression of work done is
![W = Fd cos\theta](https://tex.z-dn.net/?f=W%20%3D%20Fd%20cos%5Ctheta)
Work done to move the sled is given as 187.2 J
Explanation:
As we know that the formula of work done is given as
![W = Fd cos\theta](https://tex.z-dn.net/?f=W%20%3D%20Fd%20cos%5Ctheta)
here we know that
F = 12.6 N
d = 15.4 m
![\theta = 15.3 degree](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2015.3%20degree)
so we will have
![W = 12.6 \times 15.4 cos15.3](https://tex.z-dn.net/?f=W%20%3D%2012.6%20%5Ctimes%2015.4%20cos15.3)
![W = 187.2 J](https://tex.z-dn.net/?f=W%20%3D%20187.2%20J)
The average speed of the car for the entire trip can be calculate by using:
![v=\frac{S}{t}](https://tex.z-dn.net/?f=%20v%3D%5Cfrac%7BS%7D%7Bt%7D%20%20)
where S is the total distance covered by the car, and t is the total time taken.
The total distance travelled by the car is:
![S=80 km+50 km+40 km=170 km](https://tex.z-dn.net/?f=%20S%3D80%20km%2B50%20km%2B40%20km%3D170%20km%20)
while the total time taken is:
![t=1.00 h+0.50 h+0.50 h=2.00 h](https://tex.z-dn.net/?f=%20t%3D1.00%20h%2B0.50%20h%2B0.50%20h%3D2.00%20h%20)
so, the average speed of the car is:
![v=\frac{S}{t}=\frac{170 km}{2.00 h}=85 km/h](https://tex.z-dn.net/?f=%20v%3D%5Cfrac%7BS%7D%7Bt%7D%3D%5Cfrac%7B170%20km%7D%7B2.00%20h%7D%3D85%20km%2Fh%20%20%20)
so, the correct answer is (3) 85 km/h.
I think it 32, but i’m not sure
