Answer:
Retroviruses or reverse transcriptase
Explanation:
Retroviruses are viruses in which the genetic material consists of ribonucleic acid (RNA) instead of deoxyribonucleic acid (DNA). Retroviruses produce an enzyme known as reverse transcriptase that uses RNA as a template to manufacture DNA, which can then be permanently integrated into the DNA of the infected host cells.

Your answer is C the objects should attract to each other due to Newton's laws.
3) there are more consumers than producers
Hopefully this helped and good luck.
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
Both provide approach to confirming the result of experimentation.
