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.

Enzymes can be denatured unfolded by what environmental factors
erastova [34]

Enzymes can be denatured unfolded by heat or chemicals.

<h3>What are enzymes?</h3>

Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.

The factors that can denature enzymes include heat and chemicals. This is because:

  • Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.

  • These environmental factors can alter the pH level of the enzyme.

Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.
