Answer:
d
Explanation:
D the grass will become dry and die
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:
A. 90%
Explanation:
Only 10% can transfer from level to level.
Answer:
nope that not possible because O has no antigens which can donate any blood group but A donates to same blood group bcoz of same antigen.
The differences between osmosis and diffusion it that diffusion refers to the movement of any chemical from one place to another, whereas osmosis exclusively refers to the movement of water across the semipermeable membrane. (cell membrane)
