Antigens are molecules that can induce an immune response. They are proteins that are found at the surface of a pathogen. Antigens are often foreign, and they are unique to a specific pathogen. When an antigen present to the body, the immune (defense) system produce antibodies against the antigen, the antigen is the molecules that the immune system recognizes and produces antibodies against.
The antigen can be any molecule. It can be a protein, nucleic acid, or polysaccharides. On the other hand, pathogens are organisms or substances, especially microorganisms, that are capable of causing diseases. Most of the pathogens we hear about are bacteria, viruses, protozoa, or fungi. Microorganisms are not considered to be pathogenic until they have reached a specific population size that they can cause disease. I hope you find this information helpful.
The muscules are connected to the bones, so when the nerves tell the muscle to contract or relax it moves the bone(s) causing movement. When you go limp, its simply because no-thing is stimulating the nerve that makes the muscle contract.

Dynamic postural stability was defined as the ability to shift and control the COG within a changing base of support. The base of support in each case referred to both the foot position and surface condition remaining stationary.
Maintain COG over a secure base of support while standing and moving unstable surfaces. Transfer COG under a fixed base of support to elected ranges and directions. In general, expanding the size of the base of support increases stability.

The answer is GLYCOGEN, not DEXTRIN. Dextrins are hydrolysis products of glycogen.
If you would need to know what hip strategy is, you can choose the first three given choices. A, B, and C are the right answers. There are different strategies that the body has to follow so that it can maintain its balance. The first is the ankle strategy, second is the stepping strategy, and finally, the hip strategy.
If any of these strategies are not working well, then it will be harder for the person to stay up or to keep his balance. The hip strategy will allow you to keep your balance when you have a narrow base of support.
You can also make rapid hip movements with the anti-phase rotation of your ankle. This is also relied on heavily especially when you find yourself falling forward or backward.
The world has many bays. A bay is surrounded for the most part by countries of land and then it has an opening into an ocean. There is usually a large shoreline around a bay. A gulf is much larger in size than a bay. Sometimes, rivers dump their water into bays. Many ports are set up on the edge of the shoreline that overlooks a bay.
The Bay of Bengal is located next to the Indian Ocean with India, Bangladesh, Myanmar, Thailand and Malaysia surrounding this bay. Another famous bay is the Hudson Bay. In this case, the bay is not surrounded by several countries, but only by one, Canada. This bay eventually dumps the water into the Atlantic Ocean and is surrounded by Canada’s provinces or territories.

The pH of gastric acid is1.5 to 3.5in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ATPase. The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide.
