All of the statements above
except "most only thrive in narrow range of environments," is true
for the eubacteria. They are organisms that can be found in every habitat on
Earth. Some of these bacteria are responsible for the diseases that we contract
but they also play a large role in the Earth's ecosystems as decomposers and
heterotrophs. They have genetic structures that help them thrive and survive in
extreme environments.

<span>Size and complexity are limited in systems usually by a combination of factors. Such as access to resources. Successful reproduction. Evolution over time dictates what is a successful balance in size and complexity in a system in its environment. If the resources are there and there is successful adaptation to the environment, systems can be supported that are extremely complex and also huge in size. Say the human body as a system.</span>
B.
Homogeneous means one mixture, so like salt water. It looks like one mixture.
Heterogenous means different mixture. Comparable to a bag of Chex mix. So if the magnet can attract the pieces of Iron, it has to be a separable mixture. Compounds would require a chemical reaction to separate.
