Answer:
A. Glucose:
As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.
B. lactose:
In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts. The same result will be in all test except in the case of a mutant repressor.
C. glucose and lactose:
In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose. the given two cases :
Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B.
The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.
Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.
The question does not provide any options, I found the options and here are the options:
<span>A) Sights often create strong emotional responses.
B) The cingulate helps you express your emotional state.
C) Emotional states can alter our blood pressure.
D) Your amygdala judges facial expressions for danger.
</span>
The correct choice is "A", " Sights often create strong emotional responses".
The sense which is more directly
involved with a person’s limbic system is the sense of smell and because of
that it is the sense of smell which should or is more likely to initiate
emotional response.

Answer:
B. a graduated cylinder to measure 30 mL of water for each plant daily
Explanation:
<em>Option A is incorrect because an electronic balance is used to measure the mass of an object and not the volume.</em>
<em>Option C is incorrect because a metric ruler is used to measure the dimension of objects and not the mass.</em>
<em>Option D is incorrect because a thermometer is used to measure temperature and not pH.</em>
The correct option is B. A cylinder is applicable in the measurement of volume of liquids.
