What is the definition of the words virus, virion, and viroid. What are the differences between each?

Answers

Virus is an agent that causes an infectious disease.
Virion is a complete virus fragment.
Viroid is an agent that causes an infection to plants.
Differences:
1. Virus has a protein coat that surrounds the RNA or DNA core but has no semipermeable membrane.
2. Virion has RNA and DNA core coated with protein and external envelops indicating as an extracellular infectious form of a virus.
3. Viroid is kinda similar to a virus. Thus, it only has single strand of RNA and has no protein coat.

The terminal portion of the small intestine is known as the ________.A. duodenum
B. ileum
C. jejunum
D. pyloric sphincter

Answers

The terminal portion of the small intestine is known as the ileum. 

Final answer:

The terminal part of the small intestine, after the duodenum and the jejunum, is the ileum. It is the last part before the large intestine begins.

Explanation:

The terminal portion of the small intestine is known as the Ileum. It is part of the small intestine that comes after the jejunum and just before the large intestine. The small intestine is divided into three sections: The duodenum, the jejunum, and finally the ileum. The duodenum is the first section, originally connected to the stomach via the pyloric sphincter, followed by the jejunum, and ending with the ileum.

The terminal portion of the small intestine is known as the ileum. It is the longest portion of the small intestine, extending from the jejunum to the large intestine. The ileum is responsible for the absorption of nutrients, including vitamins, minerals, and bile salts.
