The complementary base pairing of the DNA is the two strand of the DNA molecules have the complementary base pairs in the structure.
<u>Explanation:</u>
The DNA strands contain the nucleotide sequence which helps the strand to supply the information needed for the molecules to produce the partner in the DNA structure.
If the strands of the DNA molecules are separated then each sequence can be used as a pattern, so it can template to produce the complementary strands in the DNA easily.
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>
The acceptable macronutrient distribution range (amdr) for carbohydrates is 45 to 65 percent of daily energy intake.
