Acrylamide does not form, or forms at lower levels, in dairy, meat, and fish products. so the enzymatic degradation of lactose in dairy produts can reduce the acrylamide.

Alpha-lactalbumin is a major milk whey protein. It is involved in the process of lactose synthesis. The first transgenic cow was produced with human alpha-lactalbumin gene introduced into it. The milk of transgenic cow contained about 2.4 grams/lit of human protein.

When the transgenic mice were a few weeks old, they were given drinking water containing zinc. Mice carrying the transgene grew to twice the size of their litter mates because the metallothionein enhancer sequence stimulated by zinc had increased growth hormone production.

A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid. Synovial joints are capable of the greatest movement. Knees, elbows and shoulders are examples of synovial joints. Since they allow for free movement, synovial joints are classified as diarthrosis. They allow for many types of movement including gliding, angular, rotational etc. So, the correct answer is 'Synovial joints'.

There are several examples of these joints in the human body, including joints between the bones of the skull, joints in the pelvis and joints between the teeth and the mandible, or lower jaw, and the maxilla, or upper jaw. Another name for immovable joins is a synarthrosis, which simply means immovable. The two types of immovable joints are fibrous joints and cartilaginous joints.

In the joint there is a fluid which acts as a llubricant. This fluid is called the synovial fluid.
