Why is carbon found in the backbone of most large organic molecules? you may select more than one correct answer. a. carbon makes 4 bonds with other atoms, creating a geometry that allows for large molecules. b. carbon is very electronegative and makes hydrogen bonds with other atoms, creating a geometry that allows for large molecules. c. carbon makes shares 4 pairs of electrons with other atoms, creating a geometry that allows for large molecules. d. carbon forms ionic bonds with other atoms, creating a geometry that allows for large molecules.

Correct answer is A.

we know that carbon have 4 outer shell electrons so it can make 4 bonds and complete its octet and be stable.

Hope it helps. if you need more info ask.

g1

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
