If i remember correctly they should be adenine (A), thymine (T), guanine (G) and cytosine (C). i hope this helps. sorry if they arent all correct.
Group behavior is like being open to the others and having a nice time, individual behavior is like silent and thinking.
Comparitive: Group behavior can be loud and full of conversations while individual behavior is like no conversation and silent.
Contrast: Group and Individual behaviors are the opposite of eachother
Hope this helps!
