There was a time when we were very physically active, but now we rely on devices to do most of our work. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species.
Answer:
Cubic zirconia can be described as the cubic crystalline of zirconium dioxide (ZrO2). Diamond can generally be described as the solid form of Carbon. Cubic zircona is often used as a substitute for diamond.
Similarities between cubic zirconia and diamond include:
- Both can be used in the making of jewelry or ornaments.
- Both are durable.
- Visually, both cubic zirconia and diamond are very much like each other.
- Both cubic zirconia and diamond are hard.
Answer: protein conformation has been destroyed due to heat
Explanation:
Proteins are made up of several polypeptide chains linked by hydrogen bonds, and peptide bonds among their amino acids subunits.
At elevated temperatures, the hydrogen and peptide bonds are cleaved resulting in change in conformation of the protein. At this point, cooling DOES NOT renature the protein, as its bonds have been broken.
Answer:
True
Explanation:
Granite is less dense than basalt mainly because granite is made up of lighter mass minerals like quartz and feldspars.
