As streams flow through Stone Mountain, layers of sand build up. Over time, the sand particles form a sedimentary rock called sandstone. What causes sandstone to change into metamorphic rock at Stone Mountain? Sandstone experiences intense heat and pressure.

Explanation:
Answer: Accordingly, what is the difference between an epiphyseal plate and an epiphyseal line? The Epiphyseal plate contains cartilage used for producing bone. The Epiphyseal line is formed after the epiphyseal plate has stopped producing bone). The Periosteum is the covering of a bone.
Explanation:
Pressure is force divided by area, P = F/A, so we don't actually care about the dimension of depths, the 0.20 m, in this problem at all. All we have to do to get the area of the boxes is multiple the length times the width, or A= Area = 0.60*0.50 = 0.30 m², then we can just take the 70 N of force and divide by that area to get pressure. So P = 70 N/0.30 m² = 233.33 Pa. Pascals (Pa) are the standard unit of pressure and are the same thing as N/m².
Answer:
Polymers
Explanation:
- Polymer substrates are the main components in this tissue engineering. Polymer substrates provide the essential factors for physiological regeneration process. Polymer scaffolds are combination of polymers with, drugs, cells, can be used for therapeutic treatment of diseases and also for regeneration of several vital organs of human body such as ear, blood vessels, coronary artery etc.
- Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
