Answer:
Option A. inducer.
Explanation:
The lac operon is an inducible operon. The presence of lactose allows the gene expression for the metabolism of lactose. The IPTG mimics the structure of allolactose. The allolactose is the direct inducer of the gene of lac operon. Lactose by converting to allolactose act as a inducer. The repressor in the lac operon binds with the operator region and thus inhibits the process of transcription.
The allolactose binds with repressor and thus inhibits its binding to operator thereby initiating the process of transcription. As the IPTG mimics allolactose so it binds with repressor and act as a inducer. Thus, option A is correct.

Which of the following forms would you use to gain insight into the daily nutritional habits of a client?
A. Comprehensive client form
B. PAR-Q
C. 3- day dietary record
D. Food intolerance
The correct answer is 3-dietary records
Explanation:
In health, nutritional habits refer to the consistent preferences of an individual when choosing what to eat, as well as, how much to eat and how frequently. This information is key to help people improve their nutritional habits and health, which might include losing weight, reduce the risk of certain diseases, etc.
Additionally, one of the best ways to understand the nutritional habits of a person is through a 3-day dietary record, which is a type of format in which the individual needs to record all foods and drinks for three days including the quantity of each food and drink and the time. This is the best format for this purpose because it specifically focuses on nutritional habits, while others such as PAR-Q or food intolerances are not directly related to this aspect of health.

Blue eyes are a recessive trait meaning Pats parents would both be heterozygous with one dominant gene and one recessive for each parent.
