During body temperature regulation, temperature receptors in the skin communicate information to the brain (the control center) which signals the effectors: blood vessels and sweat glands in the skin.
        
                    
             
        
        
        
2. Because the gravitational force from anything that small compared to a planet is so minuscule it's nearly impossible to feel or measure.
3. Because do not have life and other processes necessary to create the gasses and substances necessary to create an atmosphere.
4. If the amount of mass lost was large enough it would likely allow the moon to eventually orbit away

Answer: B (GTP serves as the energy input for AMP synthesis from IMP) 
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP. 
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
