I swaped the ak for a bow, but Im not sure how to give the scientist arrows? He has a bow and an arrow, and he aims but wont shoot. 

This is what I have in the Easy Base profile:

"Scientist Items": [
"bone.armor.suit",
"bow.hunting",
"arrow.bone"

I don't think they can shoot bows. Never tried lol. Their AI handles all of that, not the plugin.
