Which of the following best describe the main function of the cyrculatori system ? a. to deliver nutrients an other essential material to cells an remove waste products

b. to break down the nutrients found in food so that they can be used by all cells in the humand body

c. to produce the chemical signals that allow parts of the humand body to communicated over long distances

d. to coordinate all others humand body system so that they can function together to maintain homeostaisis

D

Explanation:

To coordinate all other human body system so that they can function together to maintain homeostasis

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
