If the statement is asking whether it is true or false, the
answer is true because eating breakfast and skipping snack before lunch is
considered to be a type of behavior modification in which a behavior
modification focuses to the behavior change is being limited because of the
observation seen or employed.
Answer:
B: Population
Explanation:
Population is the number of people (well species) living in the same area at the same time.
Cellular respiration : aerobic :: fermentation : anaerobic
Answer:
E
Explanation:
I think bcuz arises as the result of total nondisjunction of chromosomes during mitosis or meiosi
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.
