Could you add a little more to this question, please?
Options for part A are as follows:
A) A mutation in the operator sequence
B) A mutation in the lac-Z gene
C) A mutation in the lac-Y gene
D) A super repressor mutation
Answer:
The correct answer:
Part a - A mutation in the operator sequence
Part b - It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part C. true.
Explanation:
part a:
If there is a mutation in the operator sequence leads to prevent binding of the repressor which leads to allowing constitutive expression of the genes various conditions.
part b:
The biological role of the lac operon makes sure that the cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part c:
RNA polymerase cannot transcribe the structural genes due to the repressor binds to the lac operator, therefore, the proper function of the lac operon is possible when the placement of the operator sequence between the promotor and the structural genes.
Answer:
Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
<h3><u>Answer;</u></h3>
Evaluate the validity and reliability of processes and findings.
<h3><u>Explanation</u>;</h3>
- <em><u>Scientific argumentation is a stage of scientific inquiry in which scientists make claims, based on observable evidence, and then clarify with justification of the evidence as relevant to the claims.</u></em>
- <em><u>It is therefore, an important part of scientific inquiry as it aims evaluate the validity and reliability of processes and findings. Scientific claims from an investigation should be based on evidence that is justified based on the claims.</u></em>
