On average, how many neutrons does one atom of bromine (Br) have?
NOTE:
- atomic #= 35
- atomic mass= 79.9
a) 35
b) 44.90
c) 45
d) 79.90
(Test 1) - CORRECT ANSWER IS b) 44.90
to determine the number of neutrons (n), subtract the atomic number (35) from the
atomic mass (79.9)
79.9 - 35 = 44.90

Which gland is responsible for the regulation of calcium levels?
a) parathyroid glands
b) thyroid glands
c) adrenal glands
d) pancreas
(Test 1) - CORRECT ANSWER IS a) parathyroid glands

a) distributing vital substances (such as nutrients) throughout the body
b) blocking pathogens that cause diseases
c) sending leaked fluids from the cardiovascular system back to the blood vessels
d) storing bodily hormones that influence gender traits
(Test 1) - CORRECT ANSWER IS b) blocking pathogens that cause diseases
"The integumetnary system includes skin, hair, & mucous membranes, all of which are
