Answer:

The pressure of a gas increases in a closed container if the volume of the gas decreases. Pressure and volume have inverse relationship which means if one increases the other decreases and vice versa. If pressure increases, volume of a gas decreases because there are a lot of empty spaces present between gas particles which are filled when gas particles come closer to each other due to pressure applied.

If the pride is taken over by new individuals, what happens to the females? males? cubs?.
Nookie1986 [14]

The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.

  • Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.
  • Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.
  • When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.
