Jeremy's trainer should have taken a physiology class. if he had, he would know that the use of steroids (in addition to other problems) actually which is counterproductive to improving bone density.

The answer is Parathyroid Hormone (PTH). Steroids reduce calcium levels in the blood. This results in activation of the parathyroid hormone that is essential in the metabolism of calcium in the blood. PTH induces reabsorption of calcium from bones to restore homeostasis Ca2+ levels in the blood hence causing osteoporosis. Osteoporosis causes an increased risk of bone fractures.

the answer would be knowledge about cars!

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
