What are amino acids?
In RNA, adenine base-pairs with this base.
What is uracil?
Organelle that makes most ATP in eukaryotes.
What is the mitochondria?
A perfect sphere fits through an opening only if that opening is at least this shape with a matching diameter.
In free fall (ignoring air resistance), all objects accelerate at the same rate because of this.
What is gravity?
The urea cycle primarily occurs in this organ.
What is the liver?
In an exothermic reaction, ΔH is positive or negative?
What is negative?

End product of glycolysis
What is Pyruvate, NADH, and ATP
During DNA replication, which enzyme synthesizes RNA primers?
What is primase?
Enzyme that synthesizes RNA from a DNA template.
What is RNA polymerase?
If the TOP view is a circle and the FRONT view is a triangle with the point on top, the solid is most consistent with this.
What is a cone?
Ohm’s Law relationship between voltage, current, and resistance.
