Maintaining blood glucose levels is an important homeostatic activity of the body, not specifically because every cell of the body must have glucose but primarily because the brain relies on glucose for its metabolism. a. True
b. False

a. True.

Explanation:

Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.

multiplying and dividing the two decimals and the eqations by the same number of the overalls

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
