Explanation of Solution
A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule. The capsule is linked with the accessory ligaments. The ends of the joint bones are surrounded by a smooth glass-like hyaline cartilage.
The fibrous joints are sutures, gomophoses, and syndesmoses. Suture is narrow and joins most of the bones of the skull together. Syndesmosis is a slightly movable joint where bones are joined together by a connective tissue.
The fibrous joints are attached to each other by a connective tissue. This tissue consists of collagen fibers. The fibrous joint has three types, namely, suture, gomphosis, and syndesmoses.
The cartilaginous joints are attached to each other by a cartilage. It allows more movement between two bones as compared to the fibrous joint. The primary cartilaginous joints are known as synchondroses and the secondary cartilaginous joint is symphysis.
The synovial joint is known to be diarthrotic. It joins with the fibrous joint capsule that is continuous with the periosteum of the fixed bones. It consists of an outer boundary of synovial cavity.
Amphiarthrosis is a kind of continuous and slightly movable joint. The contiguous bony surface can be symphysis that is connected by broadly flattened discs and an interosseous membrane. It is seen in cartilaginous joints.
The cartilaginous joint involves the fibrocartilage or the hyaline cartilage. The joints are slightly movable, that is, they are amphiarthrotic. They are connected by cartilage and allow the movement of bones.
The fibrous joints can be synarthrotic or amphiarthrotic. The sutures are synarthrotic joints and are situated between the bones of the skull. The edges of the bones are interlocked and they are bound together at suture.
The hip, shoulder, and jaw consist of a synovial joint. A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule.

- Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forward

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
