Experiment: Click Reset. Try making other changes to the ecosystem. Use the + or – buttons, or choose Diseased from the dropdown lists. Click Play and observe for at least 12 months. Record what happens below.



Summarize: Give at least one example of each of the following:

A major disturbance that the ecosystem was able to recover completely from.

A major disturbance that caused the ecosystem to collapse entirely, was when the snakes and the grass became diseased.

A major disturbance that caused the ecosystem to stabilize at a new equilibrium.

When there was an increase in the snakes and hawks.

A major disturbance that caused the ecosystem to completely collapse.

Having a population of grass that is diseased.

A major disturbance that almost caused a total collapse, but that the ecosystem was able to recover from eventually.

A major disturbance that the ecosystem was able to recover completely from the grasses which is diseased.

Explanation:

If the grasses were diseased, the ecosystem will recover itself from this type of disturbance. If the population of snakes and hawks increases so the ecosystem will recover itself from this disturbance because snakes are the food of hawks so if the population of snakes increases so more food is available for hawks in the form of snakes and that's why population of hawks also increases and the population of snakes is controlled.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
