Selective media are used for the growth of only selected microorganisms. For example, if a microorganism is resistant to a certain antibiotic, such as ampicillin or tetracycline, then that antibiotic can be added to the medium in order to prevent other cells, which do not possess the resistance, from growing. Media lacking an amino acid such as proline in conjunction with E. coli unable to synthesize it were commonly used by geneticists before the emergence of genomics to map bacterial chromosomes.

5 compound sentences using coordinating conjunctions or conjunctive adverbs to join two complete sentences. For the compound sen

Olin [163]

Answer: 1. Man has created many inventions; yet, teleportation has not been possible.

2. Rich people waste a lot of money; meanwhile, poor people barely have food for the day.

3. I haven't done my laundry, nor washed the dishes.

4. Sometimes, singers release bad music since they have pressure from the record.

5. My boyfriend lost his wallet, so I had to pay for the food.

Explanation:

Independent clauses are complete clauses that can stand on their own, but when they are next to coordinating conjunctions or conjunctive adverbs, they form a compound sentence. These five examples have two independent clauses. For instance: "Rich people waste a lot of money" and "poor people barely have food for the day" make sense on their own; however, the conjunctive adverb "meanwhile" connects and contrasts them.
