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>
Answer:
There are 2 types of charts to read amino acids,
The circle chart is read by starting from the largest letter and following the next letter until you reach an amino acid
The square chart is like graphing coordinates, start from where it says first letter of codon, find your letter, go to second letter and then third to find your amino acid
Natural selection is a one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. Diseases can act as natural selectors. That means that the weaker organism will get sick and die. Stronger will survive and have the ability to pass down their trait to the next generation. This suggests that species must have a great protecting mechanism in order to survive and reproduce.
Scavengers are an organism that mostly consumes decaying biomass.

Detritivores feed on decaying organic matter and return essential nutrients back to the ecosystem.
So the answer would be (D). Both organisms feed on pieces of other dead organisms.</span>
