Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Answer:
D. Fibrocartilage
Explanation:
In order to understand the question, we need to review the structure of intervertebral discs.
Intervertebral discs consist of two parts:
It forms the central part of the intervertebral disc and consists of mucoid substance.
It is composed of encircling layers of fibrocartilage and fibrous tissue surrounding the nucleus pulposus
<u>SLIPPED DISC:</u>
It is characterized by the protrusion of nucleus pulposus through the annulus fibrosus accompanied by the compression of spinal nerves.
Patient may present with loss of sensory sensations or pain or both.
<u>CORRECT ANSWER:</u>
From the above review, the correct answer is <u>D. fibrocartilage</u> as it forms the annulus fibrosus.
Antagonists muscles (e.g. biceps and triceps brachii)
Endocrine and circulatory (C) Endocrine system consists of glands and the hormones they secrete whist the circulatory system is the blood or as I like to call the “transport system” of the body.
The correct answer is B. Hypothalamus.
Explanation
The hypothalamus is a part of the brain that is located below the thalamus, it is an area of the brain where several and very important homeostatic regulatory functions of the organism are integrated. Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions. Therefore, the correct answer is B. Hypothalamus
