Describe homeostasis?
Ann [662]

Answer:

Homeostasis is the process of maintaining a constant internal environment of the body with the help of certain mechanisms such as feedback loops.

Explanation:

Homeostasis refers to the maintenance of a relatively constant internal environment of the body. It includes maintaining several parameters such as acid-base balance, blood glucose level, body' temperature, etc. within the narrow range.

Homeostasis is mainly maintained with the help of negative feedback loops wherein the deviation of any parameter from the normal physiological range is counteracted and restored.

For example, the blood glucose level remains within the range of 70 and 110 milligrams of glucose per 100 milliliters of blood under normal physiological conditions. Any deviation from the range is restored with the help of pancreatic hormones insulin and glucagon.

What is the life cycle for a goldfish?​
Rus_ich [418]

Answer:

The life cycle of a goldfish starts out as an egg. The female fish will lay about 25 eggs, but unfortunately only some grow up. The eggs usually hatch within 5 days and if you have a fish tank then you should take the adult fish out or else it may eat the eggs. After the egg hatches, it turns into a fry,(this is what a baby goldfish is called) Once they hatch, they will stay attached to the plants for two days, after that, you should start to feed them. Once they are not fry anymore, they turn into adult goldfish. If you take care of them properly, they could last up to 15 years! Once the fish are complete adults, they can lay eggs. The females rub up against plants and lays eggs while the male Goldfish sprays the eggs to make them fertilize and turn into fry.
