<span>In
the 19th century is was assumed that organic compounds could only be
produced by plants and animals. These compounds all had carbon and
hydrogen in common. Some organic compounds also include O, N, the
halogens, S and a few other elements.
Now we know that organic compounds can be synthesized in the laboratory.
Simple compounds of carbon and hydrogen include the alkanes and
alkenes, for instance, as well as aromatics like benzene. But oxygen is
a common element in organic compounds like alcohols, aldehydes, ketones
and ethers.
So the bottom line is that all organic compounds contain C and H and
some contain O as well, but O is not required to be an organic compound.
========= Follow up ==========
Why are these people saying "yes". It's obvious that there are many organic compounds that don't contain oxygen</span>
Mitosis is cycle... Telophase is probaly the best answer for when the cells are actually into 2

Hope this helps :)
Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
