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.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

is this a psat question, if so do not cheat try your best.
