HALF.. This is a form of replication where two copies were produced each will contain one of the original strand and the other is a new copy. This happens because each nitrogenous base should pair with the complimentary partner, such as adenine with thymine and cytosine and guanine. DNA replication happens due to the action of enzymes. Each new strands will form an identical copy of the original DNA strand. There are various models proposed to explain how replication occurs. These are the conservative, semiconservative and dispersive.

Answer:
The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).
Explanation:
The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.
As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.
The other options are not correct because:
- <em>The excretory system does </em><u><em>not introduce more oxygen into the lungs</em></u><em>.
</em>
- <em>The </em><u><em>circulation of blood in and out of the lungs</em></u><em> is a function of the circulatory system.
</em>
- <u><em>Urine is not produced by breathing</em></u><em>.</em>
