During the process of chromosome replication, a genetic error occurs. as a result, a sequence of events occurs as described below. event a. protein with the new sequence of amino acids is produced. event b: a dna strand with an altered base sequence is formed. event c: , a new inheritable trait is expressed in an organism. event d, an mrna strand with the new sequence of bases is synthesized. the usual order in which these events would occur is: 1. b-d-a-c. 2. b-d-c-a. 3. d-a-b-c. 4. d-c-b-a

In addition to seeds, which of the following characteristics are unique to the seed-producing plants? a) sporopollenin b) lignin present in cell walls c) pollen d) use of air currents as a dispersal agent e) megaphylls

In which of the following relationships is one organism always benefited while the other organism is always harmed

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
