In-s [12.5K]

Answer:

This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.

Explanation:

Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger.  On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.

dalvyx [7]

Answer:

The correct answer will be- proteoglycans and the glycoproteins

Explanation:

The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.

The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.

Thus, proteoglycans and glycoproteins are the correct options.
