Answer:
Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. The metal is a fair conductor of electricity, but a poor conductor of heat. Mercury's atomic number is 8.
Answer:
Man-made resources
Explanation:
Humanized resources are items or substances that have value to human lives that do not occur in the natural world. Examples of man-made resources include plastic, paper, soda, sheet metal, rubber and brass. These contrast with natural resources, such as water, crops, sunlight, crude oil, wood and gold.
Here are the list of nucleo bases : adenine , Thymine, Guanine , Cytosine
Adenine pairs with Thymine, and Guanine pairs with Cytosine
Adenine + Guanine = Purine
Thymine + Cytosine = Pyrimidine
So the answer for number 1 will be : Purine, since Adenine is not the choice
And the answer for number 2 is Guanine

The statement that is true for most chemical reactions is that A. An energy change occurs during the breaking and forming of chemical bonds. As the reactants react ultimately producing products the atoms of the respective elements within the compounds if present will break and reform ultimately to produce the products, during this change energy transformation from chemical bond formation and breakage occurs, and allows one to determine whether or not a reaction releases energy or needs a substantial amount of energy based on the energy content of the reactants and products.
