What are the main features of a eukaryotic cell? how do these features differ from those found in bacteria and archaea? 2. are eukaryotes monophyletic? what character(s) support or refute their monophyly? how would you characterize relationships among eukaryotes-are they well resolved?

Explanation:

1. The main features of eukaryotic cell are:

A. It has membrane bound nucleus, hence it is said to have true nucleus.

B. It has a membrane bound organelles(including endoplasmic recticulum, Gigi aparathus,chloroplast and mitochondria.

C. It has several rod shaped chromosomes.

2. These features differ from those found in Bacteria and Archaea in that: Bacteria and Archaea do not have a membrane bound nucleus, they don't have a membrane bound organelles and they do not have a rod shaped chromosomes.

3. Eukaryotes are monophyletic.

They are monophyletic because they evolved only once and they are from a single common anscetor.

4. Eukaryotes are well resolved among each other. They have a well resolved phylogeny.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
