Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland

Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.
Answer:
Perichondrium
Explanation:
Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium. The perichondrium (Figure 7–2) is a sheath of dense connective tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage. The perichondrium harbors the blood supply serving the cartilage and a small neural component. Articular cartilage, which covers the ends of bones in movable joints and which erodes in the course of arthritic degeneration, lacks perichondrium.
