Four elements that make up living things: correct answers 1. Carbon - all known life things are carbon based (comes from air through plants) 2. Oxygen - (comes from air) a lot of carbon and oxy w in our biomolecules. 3. Hydrogen - (comes from water) 4. Nitrogen - (nitrogen in plants which extract it from soil) Who do we thank for Nitrogen correct answers Fritz Haber 3 common wide array complex molecules: correct answers 1. Amino acids 2. Sugars 3.

What are the four rules for writing resonance structures? - Answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - Answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple bond. The latter compromise conj...

It is identical to the DNA coding strand. How are the basal layer of the epidermis and the innermost lining of the small intestine similar? A. both are nondividing tissues B. both are derived from ectoderm C. both are composed of squamo...
