Answer:
Astrocytes
Explanation:
Astrocytes are the most abundant cells in the central nervous system that twine around nerve cells supporting the brain and spinal cord. They perform many functions; such as providing the nuerons with nutrients, control the blood brain barrrier and blood flow. Astrocytes are basically responsible for maintaining the central nervous system homeostasis.
The technicians ask the patients if they have any steel inside their body because the steel when subjected to a magnetic field they will become a magnet. since MRI produces a very large amount of magnetic field during its operation, then the still will be a magnet and it might hurt you
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.
