Answer:
B. Are c considered plants or animals?
Explanation:
The question that will be asked to show the problems associated with this type of model is the position of bacteria in the model because bacteria are neither animals nor plants and have a completely different system.
Bacteria are single-celled while plants and animals are multicellular. Bacteria are prokaryotic so they also lack nucleus and do not have any membrane-bound organelles while plant and animals cell have.
Hence, the correct option is "B. Are c considered plants or animals?".
Answer:
Characteristics. They are all relatively inert, corrosion-resistant metals. Copper and gold are colored. These elements have low electrical resistivity so they are used for wiring.

Answer:
2.23 x 10^-4 mol
Explanation:
0°C =273 K
PV= nRT
n= PV/RT
n= (5.00 atm * 0.0010 L)/ (0.0821 * 273 K)
n= 2.23 x 10^-4
Assuming that the ammonium sulfide formula is (NH4)2S then you can see that there are 2 nitrogen, 8 hydrogen and 2 sulfur atoms for every ammonium sulfide. If the amount of ammonium sulfide is 8.9 moles, then the number of hydrogen atoms should be: 8/1 * 8.9 mol= 71.2 moles
