Answer:
a test cross
Explanation:
it determine whether row genes are linked
251.16 nitrogen gas particles
67.62 oxygen gas particles
0.13 argon gas particles
Explanation:
Air is a mixture of many gases. Different gases have their own percentage composition in air.
Nitrogen = 78%
Oxygen = 21%
Argon = 0.04%
Since the air in the container is made up of 322 particles, we can find the the number of nitrogen, oxygen and argon gases in it;
Number of Nitrogen gas =
x 322
= 251.16 nitrogen gas particles
Number of oxygen gas =
x 322
= 67.62 oxygen gas particles
Number of argon gas =
x 322
= 0.13 argon gas particles
