Answer:
c. uracil
Explanation:
uracil is not found in DNA. the missing base would be thymine
Answer:
When objects collide, energy can be transferred from one object to another, thereby changing their motion. Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light.
Answer:
The definition of an absolute reference frame would be that fixed reference frame that every observer would rest at all times in his/her state of motion.
Explanation:
<u>Answer:</u> The correct net ionic equation for the reaction is 
<u>Explanation:</u>
Net ionic equation is defined as the equations in which spectator ions are not included.
Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.
The balanced molecular equation is:

The complete ionic equation follows:

As calcium and sulfate ions are present on both sides of the reaction. Thus, they are considered spectator ions.
The net ionic equation follows:

Hence, the correct net ionic equation for the reaction is
