    What gives the inner eye its dark color?
    The dark color of the inner eye is given by the choroid. The choroid is a layer of tissue that lies between the retina and the sclera (the white part of the eye). It is rich in blood vessels and contains a pigment called melanin, which gives it a dark brown color. The choroid helps to nourish the retina and protect it from damage.

    The hormone involved in the regulation of calcium and phosphorus metabolism is secreted by the gland called:
    The parathyroid glands are small, oval bodies that are usually four in number which lie at the back of thyroid glands. They secrete a hormone called as parathormone or parathyrin. It regulates the level of calcium in the blood plasma. Parathormone and a thyroid hormone called calcitonin work antagonistically (they work in opposite ways i.e. if one increases the calcium and phosphate levels, the other will decrease) to regulate the plasma calcium and phosphate levels.
