Answer:
The black snakes will survive and reproduce while the orange snakes die out.
Explanation:
The orange snakes will be easier to see by their prey and predators, and therefore will die out while the black snakes thrive because of their camouflage.
Answer: 996 mmHg
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number 
of particles.
According to the ideal gas equation:
P = Pressure of the gas = ?
V= Volume of the gas = 25.5 L
T= Temperature of the gas = 13°C = (273+13) K = 286K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 1.42
(760mmHg=1atm)
Thus pressure of this gas sample is 996 mm Hg.
Answer:
The frequency of wave is 0.125 Hz.
Explanation:
Frequency:
"It is an event repeat itself in a given period of time"
The unit of frequency is the Hz . If time is measured in seconds then frequency will be in Hz. Hz is equal to the per second.
Formula:
f = 1/ T
f = 1/ 8 sec
f = 0.125 Hz
A) releasing CO2 that dissolves and forms acid in the oceans (i think i'm sorry if its wrong)
