Atlantic cod is a benthopelagic fish that is consumed primarily by humans. These are commercially known as codling. From the given choices, legal regulations and increasing reproductive capacity are both beneficial to the population of the cod. The water temperature is also likely to affect the population but not as much as overfishing does. Therefore, the answer is the first choice.
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:
1. Fats contain mostly C-H bonds, it has less oxygen therefore making it a high energy compound
2. mRNA plays a vital role in protein synthesis. It's a single stranded RNA molecule that contains genetic information that can be taken outside the nucleus (unlike DNA which cannot leave the nucleus). Its created during transcrption, and is used during translation to create proteins
3. (Look at image)
The answer is A. small nutrients
Answer:
Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.
