When both glucose and lactose are present in the media in which E. coli is growing the preferred carbon source of is glucose.
About lac operon:
The lac operon of E. coli contains genes involved in lactose metabolism which is expressed when lactose is present and glucose is absent.The lac repressor and catabolite activator protein (CAP) are two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations.A lactose sensor is the lac repressor. When lactose is present, it ceases to function as a repressor, blocking transcription of the operon in its usual state. Through isomer allolactose, the lac repressor indirectly detects lactose.The CAP serves as a glucose sensor. It starts the operon's transcription, but only when the blood glucose level is low. Through the chemical cAMP, CAP detects glucose in an indirect manner.Learn more about the Lac operon with the help of the given link:

q = [tex]2.5\times10^{-5}[/tex]
Let us label the four points as - A (0, 2), B (0, -2), C (2 , 0), and D (-2 , 0).
Now, the potential due to charge located at point A will be -
[tex]V_{A} = \frac{1}{4\pi\epsilon_{o} } \frac{q}{r}\\V_{A} = \frac{1}{4\pi\epsilon_{o} } \frac{q}{r}\\V_{A} = 9\times10^{9}\times\frac{2.5\times10^{-5} }{2} \\V_{A} = 11.25\times10^{4}[/tex]

A skater can spin faster by pulling her arms closer to her body or spin slower by spreading her arms out from her body due to conservation of angular momentum
What is the principle of conservation of angular momentum?
According to the conservation of angular momentum principle, an object's angular momentum will remain constant until it is affected by an external force. This explains why tucking the arms in close to the torso causes a figure skater to spin more quickly. She has a significant moment of inertia as she starts spinning because more of her mass is farther away from her axis of movement (her body).

Examine Figure 1. During the process of beta decay, which statement correctly compares the parent nucleus and the daughter nucleus?
A
The parent has a different mass number than the daughter.
B
The parent has a different atomic number than the daughter.
C
The parent has the same number of neutrons as the daughter.
D
The parent has the same number of electrons as the daughter.
Beta decay forms a daughter nucleus with a different atomic number than the parent nucleus. The correct answer is option B.
A nucleus loses an electron when it emits the beta particles. The parent and daughter nuclei share the same atomic mass because the mass of an electron is so much less than that of a proton or neutron. The offspring nucleus has an atomic number that is one higher than the parent nucleus.
There are mainly two types of beta decay: beta plus (positron decay) and beta minus (electron decay). The daughter atomic number reduces by one after beta plus decay (the nucleus loses one positive charge) and rises by one after beta minus decay (the nucleus loses one negative charge).

When the range of one or both of the variables is restricted, the correlation will be ______.
When the range of one or both of the variables is restricted, the correlation will be decreased
Restriction of range is the term applied to the case in which observed sample data are not available across the entire range of interest.
Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.
Restricted ranges affect correlations. In fact, when the range is restricted, a peculiar phenomenon happens: the correlation coefficient goes down. The range restriction causes the standard deviation of the variable x to shrink which reduces the correlation of x to some variable y. Analogue, range restriction can also affect the coefficients in multiple regression

State two examples where the factor perpendicular is practically used to increase pressure?
Pressure can be calculated by Pressure=Force/Area.
Therefore, if the area is decreased or reduced then pressure will be increased.
What is Pressure?The physical amount of force applied to a certain region is known as pressure. Pressure is defined as force per unit of area. The pressure being applied to a body may be calculated by taking the amount of force being applied and dividing it by the area of contact.
Pressure=Force/Area.

The current through a certain heater wire is found to be fairly independent of its temperature. If the current through the heater wire is doubled, the amount of energy delivered by the heater in a given time interval will.
The amount of energy delivered by the heater in a given time interval will be increase by a factor of four
Given:
Current in wire = I
current is double = 2I
To Find:
amount of energy delivered by the heater
Solution:
Scientists define energy as the ability to do work.
The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.
E = Power x Time = P x T
P = (I)^2 x T
E' = (2I)^2 x T
E' 4I^2T
E' = 4E
So, amount of energy delivered by the heater will be four time initial energy

Among merge sort and quick sort, which algorithm takes more spaces? what strategy is used by the other algorithm to use less space and run slightly faster in average case?
Merge sort requires more space than quick sort. Bogo sort is used by the other algorithm to use less space and run slightly faster in average case.
To find the answer, we need to know more about the Maxillary space.
What is Maxillary space?Quicksort consumes less space and has better cache locality than merge sort, which uses more space. An in-place sorting algorithm is quick sort. No additional storage space is required for sorting when it is done in-place. Because Join Sort does not exist, Quick Sort has the advantage of space since Merge Sort needs a temporary array to merge the sorted arrays.Thus, we can conclude that, merge sort requires more space than quick sort. Bogo sort is used by the other algorithm to use less space and run slightly faster in average case.
