Identify the best description for the cause of altitude sickness. altered signaling response in skin cells due to the increased exposure o overcompensation by the body in response to the increased gravity at oan organism's inability to absorb and transport enough oxygen o internal pressure caused by bodily fluids counteracting the decreased to ultraviolet rays at higher altitudes higher altitudes throughout the body at higher altitudes atmospheric pressure at higher altitudes

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
