1. Describe each of the three major kinds of skeletal articulations in terms of both structure and function
ans.There are three main types of joints;
1.Fibrous (immovable)
2.Cartilaginous (partially moveable)
3. Synovial (freely moveable)
Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints
Cartilaginous (synchondroses and symphyses): These joints occur
where the connection between the articulating bones is made up of
cartilage for example between vertebrae in the spine.
Synchondroses are temporary joints which are only present in
children, up until the end of puberty. For example the epiphyseal
plates in long bones. Symphesis joints are permanent cartilaginous
joints, for example, the pubic symphysis.
Synovial (diarthrosis): Synovial joints are by far the most common classification of a joint within the human body. They are highly moveable and all have a synovial capsule (collagenous structure) surrounding the entire joint, a synovial membrane (the inner layer of the capsule) which secretes synovial fluid (a lubricating liquid) and cartilage known as hyaline cartilage which pads the ends of the articulating bones.

Describe nitrogen fixation in terms of kinds of organisms reponsible for both the symbiotic and non-symbiotic types, and the materials involved in the process. I can't seem to find a nitrogen fixation process that involves organisms that are both types. Can someone please explain this to me?
