Quartz
Explanation:
Quartz is a framework silicate made up of interlocking SiO₂. It is the most resistant mineral to weathering.
This is based on the Bowen's reaction series of minerals.
From the series;
- In a given melt, quartz is the last mineral to crystallize out of solution.
- Olivine is usually the first
- Quartz being the last does not readily react with other substances.
- This makes it resistant to agent of weathering.

Answer:
Simple cuboidal epithelia are found in areas that stretch.
Explanation:
The simple cuboidal epithelium consists of a single layer of cuboid cells with a centrally located nucleus. The cells of this epithelial tissue are mostly involved in secretion and absorption and therefore, are found in the lining of ovaries, lining of kidney tubules and gland ducts.
Transitional epithelium is like a stratified cuboidal epithelium when not stretched. Its cells become flatter when the tissue is stretched. It has multiple cell layers and elasticity and therefore, is found in the lining of the urinary bladder and parts of ureter and urethra to allow stretching of these organs.
