ALL THE STATEMENTS MADE ABOVE ARE TRUE.
Viruses are considered to be non living things because they do not meet many of the criteria that are needed for an organism to be considered a living thing.
Virus can not replicate on their own, they do not excrete any waste and do not meet all the seven features that living things must exhibit.
Bacteria requires moisture to form, and salt dehydrates the cells in the meat. Killing off or keeping the bacteria at bay for however long needed.
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 answer is, <span>B) Eukaryotes
