Answer:
While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine. They are closely connected in controlling the amount of water in your body.
Explanation:
EM is created by moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light
The number of moles in a substance indicates the amount of the substance that contains the same number of particles as 12 g of the Carbon-12 isotope [or equivalent to 6.02 × 10²³] (which is used as a standard in the world of moles).
Now,
if 6.02 × 10²³ atoms are found in 1 mole of C
then let 1.65 × 10²⁴ atoms are found in x
⇒ x = (1.65 × 10²⁴) ÷ (6.02 × 10²³)
= 2.7409 mol

A sample of 1.65 × 10</span>²⁴ atoms of Carbon (C) would contain ~ 2.74 mol
749.69 ml is the new volume if, with the pressure and amount of gas held constant the temperature is decreased to 253 K.
Explanation:
Data given:
Initial volume of the neon gas V1 = 886 ml
initial pressure of the neon gas P1 = 752 torr or
initial temperature of the neon gas T1 = 299 K
Final volume =?
pressure constant so final pressure = initial pressure hence P2 = P1
fInal temperature of the neon gas T2 = 253 K
applying the Gay Lussac equation
= 
Pressure can be removed from the equation as it is constant, so we apply Charles' Law equation:
= 
rearranging the above equation to know final volume:
V2= 
V2 = 
V2 = 749.69 ml
final volume is 749.69 ml
