Yes, these actions are an example of homeostasis. To fully understand this question you need to know the basic concept of homeostasis. Homeostasis is the body's regulation. What do I mean by that? It's simple, when you have a fever your body's temperature can skyrocket to 100 or more, when you start to sweat or get the chills that's your body's way to cool you down and fight the infection. Another example; when you do any physical activity, you sweat from it depending on the intensity. If you didn't sweat you would probably overheat and that would lead to other complications. Basically when you do exercise you sweat because your body is warm and that's the homeostasis mechanism that helps cool down your body bring it to it's normal temperature. So in end answering your question in more detail by the liver regulating the body by taking glucose in when levels are too high or adding glucose in when levels are too low is an example of homeostasis because the body is regulating itself to come back to it's normal healthy function state.
Hope this helped :)
Answer
Hi,
An object with the largest size will have a large gravitational force acting on it. Explanation
The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.
Best wishes!
Your answer would be A, plant cells have rigid walls and no centrioles.
