Compare and contrast classical and operant conditioning. How are they alike? how do they differ?.
Behavioral psychology's foundational ideas include classical and operant conditioning.
The goal of classical conditioning is to establish a connection between a naturally occurring stimulus and a previously neutral stimulus.
As a reaction to the food, this unconditioned stimulus naturally and spontaneously causes salivation, which is referred to as the unconditioned response. The sound of the bell alone will begin to elicit salivation as a response after linking the neutral stimulus and the unconditioned stimulus. Now, the bell's sound is referred to as the conditioned stimulus, and salivating in response to the bell is referred to as the conditioned response.
Operant conditioning, often known as instrumental conditioning, is concerned with utilizing rewards or penalties to either promote or decrease a behavior. As a result of this procedure, a link is established between the action and its results.
Operant conditioning focuses on connecting a voluntary behavior and a reward, whereas classical conditioning links an automatic response to a stimulus.
However Both classical and operant conditioning entail associating behavior with environmental events and are guided by a number of general principles of association. For instance, it is simpler to associate stimuli that are similar to one another and occur at similar periods.

When the body's digestive system breaks down starch, a complex carbohydrate, into simpler carbohydrates, the reaction is:________
The reaction is catabolic. Catabolism is a series of metabolic pathways that break down molecules into smaller units, either oxidized to release energy or used in other anabolic reactions.
Among complex carbohydrates, starch serves as the main glucose storage molecule in plants. A large number of different glucose monomers combine to form starch and are linked by glycosidic bonds. An example of a catabolic reaction that releases chemical energy is the breakdown of starch, a complex carbohydrate, by the body's digestive system into simpler carbohydrates. C. Catabolic, which causes the release of energy, is the correct response. The anabolic process is incorrect because an anabolic reaction involves the synthesis of less complex monomers into more complex monomers. Catabolic processes also lack the ability to store energy.Therefore, catabolic reaction is the correct answer.

What do scientists do to test the way one variable affects another?
A single independent variable can be used.
In a controlled experiment, you alter one factor (an independent variable) and track the effects it has on additional factors (dependent variable).You plan an inquiry for a controlled experiment based on background research and your hypothesis.Conducting at least 5 trials for each level of your independent variable is a good strategy to increase your confidence in your findings.Variables are elements that can alter in an experiment. Independent, dependent, and controlled variables are the three different categories of variables used in scientific experiments. The scientist makes systematic modifications to the independent variable and monitors how these changes affect the dependent variable.Because the experiment is set up to maintain the other variables at a constant value, or "controlling" a variable, they are referred to as controlled variables. There should be just one independent variable in a proper experiment.Therefore, controlled experiment with single variable can be used.

The difference of a number and 16 is the equal to 45 what is the value of that number? Plss show work and explain
Answer:
So your two numbers are 10 and 25.
Explanation:
Call one of these numbers x and one of them y.
We know x+y = 35
We know x-y = 15
Add y to both sides of the second equation to get x=15 + y
Then plug this into the first equation as x --> (15 + y) + y = 35
This simplifies to 15+2y=35 by adding the y's.
We can subtract 15 from both sides to get 2y=35-15, which is 2y=20. Then divide both sides by 2 to get y=10. This is one of the numbers!
Then plug this back in to either equation above. I'll use the first equation that is x + y = 35. y=10, so x+10=35. subtract 10 from both sides to get x=35-10, so x=25.

If m∠4 = 35, find m∠2. Explain.
35; ∠2 and ∠4 are alternate interior angles, so m∠2 = m∠4.
145; ∠2 and ∠4 are supplementary angles, so m∠2 = 180 − m∠4.
55; ∠2 and ∠4 are complementary angles, so m∠2 = 90 − m∠4
35; ∠2 and ∠4 are corresponding angles, so m∠2 = m∠4.
The correct answer is option 1.
From the accompanying photo,
Right triangle CAB has three sides.
Consequently, m1 = 90°.
Similarly, mACD = 90°
∠ACD = 90° = ∠ACB + ∠BCD
= m∠3 + m∠4 = 90°
Because m4 = 35°,
m∠3 + 35° = 90°
m∠3 = 90° - 35° = 55°
In the ABC triangle,
∠ACB + ∠CBA + ∠BAC = 180° [triangle property]
∠3 + ∠2 + ∠1 = 180°
55° + ∠2 + 90° = 180°
∠2 + 145° = 180°
∠2 = 180° - 145° = 35°
Because ABCDBC is a transversal,
The lines are referred to as transversal lines when a straight line crosses two or more parallel lines. Any time this transverse line crosses a coplanar line, alternate angles—also referred to as exterior or interior alternate angles—are created.
In light of this, ∠2 = ∠4 = 35° [Alternate Interior Angles].

5) integrators
Option 1: In expressing the mammalian genes in e.coli, the most formidable obstacle is Introns.
Introns are the nucleotide sequences that do not directly code for proteins. They reside in the genes of an organisms and are generally removed during transcription of an RNA molecule.
Our DNA comprises exons and introns, where exons are coding parts while introns are non-coding parts. Introns get stuck in between which leads to stopping the coding of DNA because it does not form any kind of protein. These are like gap which is not coded for protein. So to avoid this obstacle we replace it with exons by the process of splicing. This is because exons form proteins and thus can participate in DNA coding (as DNA is responsible for the synthesis of proteins). These are found in all creatures and all types of genes.

Will there be a greater difference between the genome or the proteome between these two cells?
Answer:
A proteome comprises the entire map that includes all the proteins which will result from just a single gene, but a genome simply consists of genes that encode for proteins. As a result, there will be a significant size difference between the two. For instance, the genome of a skin cell is identical to the genome of another somatic cell, yet the proteome of a kidney cell comprises proteins such as angiotensin, tomm-Horsfall protein, etcetera. The proteome of the kidney cells is several times greater than that of the genome of skin cells, and each of these proteins might well have descended from a single gene.
