Biology Questions

The nucleus of a cell contains chromosomes, which carry genetic information in a long molecule called DNA.

Genes are regions of DNA that carry the code to control a particular cell activity or the production of a particular protein.

True, poorly controlled stress and anger can lead to heart attacks and strokes.

A cytoskeleton acts as a frame that gives a cell its shape, protects it to an extent, and helps with cellular motion.

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.

Bones of shoulder, thigh and foot are the part of appendicular skeleton. 

Hence, Vertebral column is the part of axial skeleton.
