Answer:

The two prokaryotic domains are Archaea and Bacteria.

The eukaryotic domain is Eukarya.

Both prokaryotic and eukaryotic are similar in which they have a plasma membrane and cytoplasm; meaning all cells have plasma membrane surrounding them. A difference between Eukaryotic and Prokaryotic is that eukaryotic have organelles, for example, a nucleus. Prokaryotic cells do not have a nucleus.

<span>2) What is the formula of a compound formed between iodine (I) and calcium (Ca)?
Calcium will always give two electrons. but iodine can receive only one. Therefore two atoms of iodine react with one atom of calcium to give CaI2. Their bond is an ionic bond.
Ca 2+ + 2I 1- --> CaI2</span>

<span>3) What is the resulting formula unit when strontium (Sr) and phosphorus (P) bond?
Strontium (Sr) wants to lose two (2) electrons, and phosphorus (P) wants to gain three (3). By using the criss-cross method, if you flip the 2 and 3 to the opposite elements, you will end up with the formula Sr3P2.</span>
