Answer;
-Chitin is a structural carbohydrate that forms their exoskeleton
Explanation;
-Chitin is the main component in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi.
-It is a linear long chain polymer consisting of repeated units of N-acetyl-glucosamine.
-The main function of the chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury and also prevents the delicate tissues from drying (acts as a water tight barrier against dehydration).

Answer:</h2><h2>KAROTYPE:</h2>
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
<h2>_____________________________________</h2><h2>CHROMOSOMAL NUMBER 18:</h2>
Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
<h2>_____________________________________</h2><h3>TRISOMY 18:</h3>
Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.

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.
They both act like filters. The coffee filter makes sure that coffee doesn't go in the drink and the kidney makes sure solids don't pass by.
This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills. These body parts work like a pump to keep water moving over the gas absorption surfaces of the gills.
