A student states that nonmetal atoms form covalent bonds by gaining electrons until they have eight valence electrons. What is wrong with this statement?
A. Nonmetal atoms do not usually form covalent bonds.
B. Covalent bonds form when atoms share electrons.
C. Nonmetal atoms form bonds until they have six valence electrons.
D. Covalent bonds form between atoms that already have eight valence electrons.

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material

What type of chemical reaction occurs between silver nitrate (agno3) and copper (cu)? the equation i was given is 2agno3 + cu —> 2ag+ cu(no3)2.

Compare and contrast an assemblage and a pollen fingerprint by defying both and giving examples of each from the chapter.
