Explanation
Synarthrosis refers to a type of joint that is immovable or has very limited movement. The skull is composed of many bones that are connected by immovable joints called sutures. These sutures allow the skull to maintain its shape and provide protection to the brain. Therefore, the correct answer is the skull.

Explanation
Abduction, Rotation, and Gliding are all types of muscle movement. Abduction refers to the movement of a body part away from the midline of the body. Rotation involves the movement of a body part around its axis. Gliding refers to the smooth movement of one body part over another without any significant change in angle or rotation. Swivelling, Reciprocating, and Venturing are not types of muscle movement, hence they are not the correct answers.

Explanation
The alimentary canal refers to the entire pathway of the digestive system, starting from the mouth and ending at the anus. It includes various organs such as the esophagus, stomach, small intestine, and large intestine. The length of the alimentary canal is approximately 9 meters, as it needs to be long enough to allow for the proper digestion and absorption of nutrients from food.

Explanation
The statement is true because the health of the gastrointestinal tract is indeed maintained by a diverse community of bacteria. The human gut is home to trillions of bacteria, collectively known as the gut microbiota. These bacteria play a crucial role in digestion, absorption of nutrients, and the overall functioning of the immune system. The gut microbiota consists of hundreds of different strains of bacteria that work together to maintain a healthy balance in the gastrointestinal tract.

Explanation
The skull is made up of 22 bones. These bones include the cranial bones, which form the top and sides of the skull, and the facial bones, which make up the front of the skull.

Explanation
The brain is not comprised of four parts. It is actually composed of several different regions and structures that work together to perform various functions. Some of the main parts of the brain include the cerebrum, cerebellum, brainstem, and the limbic system. Each of these parts has its own specific role in controlling different aspects of our thoughts, emotions, and bodily functions. Therefore, the statement that the brain is comprised of four parts is incorrect.

Explanation
The statement is false. The iris and the choroid are two different structures in the eye. The iris is the colored part of the eye that controls the size of the pupil, while the choroid is a layer of tissue that is located between the retina and the sclera (the white part of the eye).
