reactant of respiration?

Which of the following mutations could lead to constitutive expression of the genes of the lac operon? View Available Hint(s) Wh
Molodets [167]

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.

kow [346]

Answer: Option C

Explanation:

A biological species can be defined as the concept which includes the group of individual which lives in one or more population that can reproduce among each other to produce viable species.

Speciation is the phenomenon by which one group of species gets separated from another. The species gets diverge due to reproductive isolation or due to geographical isolation.

Hence, the correct answer is option C

Why do Plants cells have cell walls and Animal cells do not?​
zimovet [89]

Answer:

Plants need a rigid structure. Animal cells have flexible cell membranes. So animal cells can have a variety of shapes, but plant cells can not, they have to take the shape of their cell walls. Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.

How are cells from one organism different from or similar to the cells of another? How might you answer the question after you o
Reika [66]

In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.

Just a little while after you started out as a fertilized egg, your cells started performing specific tasks, even started to look different because of that. Differentiation means that one cell performs a different function than another cell, depending on where it is in your body.

Not sure if this will help.
