Answer:
Diamond
Explanation:
Diamond has covalent bonds, which makes it a non-metal.
However, it also has a tetrahedral structure, which holds its C atoms together by strong forces, thus making it hard.
Diamond also has free-moving electrons due to its tetrahedral structure, thus making it possible to conduct electricity.
The persistence of vision is regarded as an optical illusion but it is actually part of human physiology.
<h3>What is persistence of vision?</h3>
The term persistence of vision is the idea that an object is able to remain is sight for a long time even when the object has been removed. This is often used by performers to create a remarkable impression on the audience. The persistence of vision is regarded as an optical illusion but it is actually part of human physiology.

Answer:
Yes
Explanation:
Denatured ethanol fuel is a polar solvent, which is soluble in water. A
Polar solvent is a compound with a charge separation in chemical bonds, such as alcohol, most acids, or ammonia. These have affinity with water and will dissolve easily. Denatured fuel ethanol has a flash point of -5 ° F and a vapor density of 1.5, indicating that it is heavier than air.
Consequently, ethanol vapors do not rise, similar to the gasoline vapors they are looking for lower altitudes. The specific gravity of denatured fuel ethanol is 0.79, which indicates that it is lighter than water and has a self-ignition temperature of 709 ° F and a boiling point of 165-175 ° F. Like gasoline, the most denatured fuel, the greatest danger of ethanol as an engine fuel component is its flammability.
It has a wider flammable range than gasoline (LEL is 3% and UEL is 19%).
I believe it is B. Green pods are recessive.
