Substitution

Explanation:

Deletion would be deleting (C)

Insertion would be inserting another letter

C. Substitution

Explanation:

Mutations occur when a gene sequence is changed in one way or another. In this case, the 6th base, C, was swapped with an A. This is a substitution mutation where one base is substituted for another. An easy way to tell this is substitution is that the number of bases does not change in the mutated sequence.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
