    The mean normal blood glucose level in humans is about 4 mM (4 mmol/L or 72 mg/dL, i.e. milligrams/deciliter); however, this level fluctuates throughout the day. Glucose levels are usually lowest in the morning, before the first meal of the day (termed “the fasting level”), and rise after meals for an hour or two by a few millimolar. Normal Human Glucose Blood Test results should be 70 - 100 (mg/ dL) before meals, and less than 180 mg/dL after meals

    Correct Option: C

    Angora wool refers to the downy coat produced by the Angora rabbit. Angora is known for its softness, thin fibres, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core, Angora rabbits produce coats in a variety of colours, from white through tan, gray, and brown to black

    For women, heart disease symptoms may be subtle – but when a heart attack strikes, women are more likely to die than men. Women are also at twice the risk of death following open heart surgery, compared to men. Researchers say when men have heart disease it affects the larger blood vessels, but in women, the small blood vessels become diseased

    In vertebrate anatomy the pituitary gland is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity covered by a dural fold. The pituitary gland secretes nine hormones that regulate homeostasis.

    Our bones and teeth are generally made up of Tricalcium Phosphate. Tricalcium phosphate is a calcium salt of phosphoric acid with the chemical formula Ca3(PO4)2. It is also known as tribasic calcium phosphate and bone phosphate of lime, BPL. Calcium phosphate is one of the main combustion products of bone. The skeletons and teeth of vertebrate animals are composed of calcium phosphate.
