B only in the nucleus and rough ER
B. A dichotomous key uses question pairs to identify organisms by their characteristics.
Correct Answer: Ratio
Determining a person’s reaction time would involve measurement on a
ratio scale that is expressed in milliseconds. It is a point where none of the quality being measured
exists and its scale has an absolute zero. In ratio scale, it allows comparisons
such as being twice as high or one-half as much. Additionally, in the case of a
person’s reaction time, it can be state that a response of 25 milliseconds is
twice as fast as a response time of 50 milliseconds.
Answer:
The correct answer is B) binds to the complementary sequence of target mRNAs
Explanation:
Double stranded RNA can be used to block the expression of target mRNAs.
At first the introduced double stranded RNA is being separated into single stranded RNAs .One of the Single stranded RNA is degraded.
The remaining Single stranded RNA binds to the target mRNA by complementary base pairing and blocks the expression of that single stranded RNA.
