The hormone that increases osteoclastic (bone break down) activity to release more calcium ions into the bloodstream is Parathyroid Hormone.
- Low level of Calcium in the blood stream stimulates the release of Parathyroid Hormone from Parathyroid gland.
- This hormone in turn stimulates bone cells to release the stored Calcium thereby increasing Calcium concentration.
- Parathyroid glands are located on the back side of Thyroid gland.
- These glands are responsible for the regulation of Calcium and Phosphorus.
- Calcium levels in blood and body should be equal and Calcium perform various functions of body such as Muscle contraction, Blood clotting, Bone rigidity.
- Hence any disturbance in the harmony of Calcium between blood and bone triggers release of Parathyroid Hormone from the Parathyroid gland.
Therefore from the above points we can conclude that Para Thyroid Hormone increases osteoclastic activity.

The most likely reason some seeds are to be covered with only 1/4 inch of soil is that <u>the seeds require light to germinate.</u>

This seed packets does not say anyhing about temperature so we can rule out higher temperature. It is really rare to plant with seeds does not have any cotyledons and also we can't really know it from the question. Etiolation response can also be found in seedlings also from this question we can't know this for sure.
Only thing that is changes if you cover the seeds with only 1/4 inch of soil is light. If you completely cover this seed with soil it wouldn't grow.
