G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>
S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>
G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>
M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>
The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.
The Circulatory System is about the Blood and the heart: they deliver oxygen to the rest of the body (except lungs). AFTER they deliver the oxygen they get the waste (Carbon Dioxide) and deliver it to the LUNGs (Respiratory System)
The Respiratory system is about the Lungs, Bronchi, Alveoli, Trachea, etc. They EXCHANGE the carbon dioxide from the blood with oxygen, they do this in the ALVEOLI (a small, grape-like sockets in the lungs).
The Digestive System consist the Esophagus, Stomach, Intestines, Gallbladder, and Anus. They Digest the food, they ABSORB the nutrients from the food we eat and we poop out the UNNECESSARY wastes.
This is an example of a placebo effect. A placebo is something that seems to be a "real" medical treatment but the truth, it isn't. It could be a pill, an injection, or some other kind of "fake" treatment. What all placebos have in common is that they do not encompass an active substance meant to affect health.
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 :)
