In case, if the inducer of lac operon [allolactose] is present in the medium during negative control, then it can bind to the repressor and decrease the binding affinity of the repressor with the operator due to which the level of transcription increases.
Operon can be understood as an arrangement having multiple genes, all of which are being regulated under the same promoter. ex- Lac operon
Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.
Under negative control, glucose is present and lactose is absent due to which no CAP [catabolite repressor protein] binding occurs, the repressor remains active and thus binds to the operator region of operon hindering the transcription process.
But, when the inducer will be present then it will manipulate the action of the repressor due to which the level of transcription increases.

help me
Answer:
There is no single attitude to contraception within Islam; however eight of the nine classic schools of Islamic law permit it. But more conservative Islamic leaders have openly campaigned against the use of condoms or other birth control methods, thus making population planning in many countries ineffective.

How is the brain involved with the senses and what is the relationship to the person to the way reacts to objects
Answer:
The five senses collects informations from the surrounding and sends to the brain.
Explanation:
The brain through the help of the five senses helps a person to react to objects in their surroundings.
The five senses of touch sight, smell, hearing and taste all have their special sensors. These sensors are what picks messages from objects and sends to the brain. The brain then interprets the message received by the person from any of the senses.

Which of the 8 characteristics prove that a virus is or is not considered living?
Answer:
Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery.
Explanation:
Viruses lack membranes. Hence, they do not show characteristics of life until they enter a living cell. On entering the living cell they use the cell machinery to multiply.

the frequency of a wave in a stretched string depends on the length L, tension T and linear density m with dimension ML-1 . deduce the formula for f in terms of L , T and M using dimensional analysis
Answer:
[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]
Explanation:
Let the frequency ,
[tex]f = L^{x}T^{y}m^{z}[/tex]
Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
[tex]T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\[/tex]
collecting the like bases, we have
[tex]T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ][/tex]
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
[tex]f = L^{x}T^{y}m^{z}\\f = L^{-1}T^{\frac{1}{2} }m^{\frac{-1}{2} }[/tex]
[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]

During the Krebs Cycle, high-energy electrons and hydrogen ions are transferred to carrier molecules to form NADH and FADH2. What are the two other molecules released during the Krebs Cycle?
Answer:
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2. ATP NAD+ NADH Citric acid is broken down into a 5-carbon compound, then into a 4-carbon com- pound. Along the way, two more molecules of CO2 are released, and electrons join NAD+ and FAD, forming NADH and FADH2.
Explanation:
Answer:
The Krebs cycle uses pyruvic acid from glycolysis to produce carbon dioxide, NADH, ATP, and FADH2.
ATP Citric acid is decomposed into a 5-carbon compound, which is subsequently decomposed further into a 4-carbon compound.
Along the way, two additional molecules of CO2 are released, and electrons join NAD+ and FAD to form NADH and FADH2.

On which side of the mountain would you be most likely to find a forest?
Answer:
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.
The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.

Write your question here (Keep it simple and clear to get the best answer). Define the tearm physicology?
Correct question: Write your question here (Keep it simple and clear to get the best answer). Define the term physiology?
Answer: physiology is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.
Explanation:
The goal of physiology is to explain the physical and chemical factors that are responsible for the origin, development and progression of life. Each type of life, from the simple virus to the largest tree or the complicated human being, has its own functional characteristics.
In the study of the human physiology, we attempt to explain the specific characteristics and mechanisms of the human body that make it a living being. The very fact that we remain alive is almost beyond our control, for hunger makes us seek food and dear makes us seek refuge. Sensation of cold make us look for warmth.
Therefore in a simple term, PHYSIOLOGY is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.
How do trees and forests evolve over time?
Answer:
The particular changes that take place are influenced by the amount of light, nutrients, and water available to the plants. The gradual change in species composition and replacement of some forest species with others over time or after a disturbance is called succession.

When a plant or animal is no longer found anywhere on Earth, it is described as
being
locally extinct
geographically extinct
biologically threatened
biologically extinct
Answer:
B. Geographically extinct
Explanation:
Lets take a moment to look at the words provided. Geographical means physical features of an area, or relating to geography. It can also relate to when we are talking about information on the Earth's surface. Extinct means that the organism is no longer alive, and that there are none left of its species. So, putting the two words together, geographically extinct means that the organism is no longer found on Earth.

What allele combination results in type A blood?
B cells can divide to form plasma cells. Each plasma cell contains many mitochondria
and an extensive endoplasmic reticulum. Referring to the function of plasma cells in your answer, explain why these features are important adaptations.
Answer:
Explanation:
The presence of mitochondria and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.

what are the importance of labour as a factor of production
Answer:
hope this is useful
Explanation:
Labour is an active factor of production. It is the factor that starts production. Land and Capital alone cannot start production, so they are passive factors. They need the active factor of production, i.e. labour to be productive themselves.
