The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
Answer: Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
The correct answer is E. Algae and Fungi
Explanation:
In biology, some groups of organisms are exclusively unicellular which means all organisms of the group are made of one cell, some are exclusively multicellular which means all organism are made of two or more cells and in some cases in a group there can be both single-celled and multicellular organisms which occur in both algae and fungi. Indeed, in these two groups, there are unicellular organisms as Chlorella (algae) or yeast (fungus) that contain only one cell and multicellular organisms such as Kelp (algae) or regular mushrooms (fungus) that are both multicellular. On the other hand, protozoa only contain unicellular organisms. This means the groups that contain single-celled and multicellular organisms are algae and fungi.
Glucose maybe because ATP wont work

Yes an organ can belong to more than one system because the organ system is the digestive system.
