What is it called when two hormones cancel each other out or have opposite effects?
mina [271]

antagonism

When two hormones cancel each other out or have opposite effects it is called antagonism.

<h3>What is an example of antagonism?</h3>
  • Traditional examples of antagonistic hormones include insulin and glucagon.
  • In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.

<h3>What does the term "antagonistic hormones" mean?</h3>
  • Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds.
  • An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).

<h3>How do antagonists to hormones function?</h3>
  • Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women.
  • GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.

Please help!
Natasha_Volkova [10]

Answer:

1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.

2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.

3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.
