What does denotation mean?

a) the sound of the word when you read it.
b) the tone of a word in writing.
c) the dictionary meaning of a word.
d) the set of ideas associated with the word.

C is the correct answer, because denotation actually means. ''the literal or primary meaning of a word, in contrast to the feelings or ideas that the word suggests."

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
