The correct answer is option d.

A vaccine refers to a biological preparation, which offers active acquired immunity to a specific disorder. A vaccine usually comprises an agent, which signifies a disease-causing microbe and is usually made from killed forms or attenuated microbe, one of its surface proteins, or from its toxins.

The agent instigates the immune system of the body to determine the agent as a danger, destruct it, and to further destroy and identify any of the microbes related with that agent, which it may come across in the coming future.

gavmur [86]

According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.

<h3>What are uni-axial synovial joints?</h3>

They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.

In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.

Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
