Sounds like you're playing TA. That's to be expected for the Terran tree-and none of those, save the innovation complex, are high level, and it's a one-off. I thought I remembered at least basic farms being available, but that may have just been DL/DA.
Actually, research lab may be one higher than you ought to have naturally, but if xeno research is one of your starting techs that would explain it. It's been some time since I've played TA, so I'm not 100% positive, though.
