The picture below shows a swamp environment. If alligators live in this environment and hunt by ambushing their prey, then which quality of this
environment would successfully allow alligators to live there by hunting with this method?
a. Fast-moving clear water with light-colored sandy bottoms
b. Slow-moving, murky water with dark-colored muddy bottoms
c. Very shallow water where alligators cannot fully submerge
d. Areas that are fully illuminated at night by bright lights

b. Slow-moving, murky water with dark-colored muddy bottoms

Explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
