Blood-Brain Barrier prevent material from moving in or out of the brain's capillaries.
What is blood-brain barrier?
- All of the body's tissues and organs depend on blood arteries to carry oxygen and nutrients to them.
- The blood-brain barrier, a special property of the blood arteries that vascularize the central nervous system (CNS), enables these vessels to tightly control the transit of ions, chemicals, and cells between the blood and the brain.
- Correct neuronal function is enabled by the careful regulation of CNS homeostasis, which also safeguards neural tissue from toxins and infections.
- Alterations to these barrier qualities play a significant role in the pathophysiology and development of various neurological illnesses.

The correct answer is B. A bony skeleton
Explanation:
In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
because a cold is a virus and not a bacteria.
