<u>endocrine</u> and <u>excretory</u>
<u />
Different glands in the endocrine system (ex: the adrenal gland) produce hormones (ex: epinephrine/adrenaline) that circulate throughout the blood to regulate various cellular processes in various areas of the body.
The excretory system is responsible for the excretion of wastes from the body. This body system includes several organs from other body systems. For instance, the lungs are technically a part of this organ system (along with the respiratory system) because the lungs remove CO2 (a metabolic waste product from cellular respiration) from the blood and out of the body when you breathe out. Another, probably even more obvious example, of organs involved in the excretory system are the kidneys, bladder...etc (i.e. urinary system).

Explanation:
Answer:
either RNA or DNA
Explanation:
The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.
Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.
