Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of glycolysis that is catalyzed by?
Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of glycolysis that is catalyzed by pyruvate kinase.
Gluconeogenesis:The tissues of some organs, including the brain, the eye, and the kidney, use glucose as their primary or only source of metabolic fuel. Glycogen stores become exhausted during a protracted fast or intense exercise, and glucose must be created from scratch to keep blood glucose levels stable. The process through which glucose is created from non-hexose precursors such glycerol, lactate, pyruvate, and glucogenic amino acids is known as gluconeogenesis.
Glycolysis is effectively reversed during glucose synthesis. However, gluconeogenesis makes use of four distinct enzymes to skip the three highly exergonic (and essentially irreversible) phases of glycolysis. The pyruvate carboxylase, PEP carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase enzymes are specific to gluconeogenesis. Gluconeogenesis can only take place in particular tissues because these enzymes are not found in all cell types. In humans, the liver and, to a lesser extent, the renal cortex are the primary locations for gluconeogenesis.

A main outcome of ivan pavlov’s research is that a neutral stimulus can become a conditioned stimulus?
A main outcome of Pavlov’s research is that a neutral stimulus can become a conditioned stimulus only in the presence of an unconditioned stimulus that triggers an unlearned response.
What is Pavlov’s conditioning?
The classic conditioning -Pavlov conditioning- is an associative learning way. It is a behavior in which stimuli and responses are associated.
In Pavlov's conditioning, an unconditioned stimulus that usually induces a given response is associated with another conditioned stimulus -neutral- that does not provoke any response by itself.
Let us review a few concepts,
Unconditioned stimuli: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, food is an unconditioned stimulus.Conditioned stimuli: neutral, innocuous, or biologically not significant stimuli. Unconditioned Responses: Unlearned response that is triggered by reflex because of an unconditioned stimulus. An example is salivating.Conditioned Responses: These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli.Initially, an unconditioned stimulus does not provoke any response, but after enough exposure to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or anticipate the unconditioned stimulus.
The classic example is the one in which a dog increases its salivation secretion as an unconditioned response when it sees food -the unconditioned stimulus-.
If the unconditionated stimulus is associated with the sound of a ring bell or a light -conditioned stimulus-, after a certain time, the dog will secrete saliva when hearing the ring bell soung or seeing the light.
If the conditioned stimulus is associated with a bad experience, there is an aversion response or conditioned fear.
The main outcome of Ivan Pavlov’s research is that a neutral stimulus can become a conditioned stimulus? Yes, but only in the presence of another unconditioned stimulus (food) that triggers an unlearned response (salivation).

What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis.Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix.The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light.The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution.The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: brainly.com/question/18316109

Birds living in this population would have an allele frequency of "b."
If the blue species of birds have homozygous dominant alleles of BB, the green species of birds have heterozygous alleles of Bb, and the yellow species of birds have homozygous recessive alleles of bb, then b is the "recessive allele" and b is the dominant allele for blue.
NOTE:The term "recessive allele" refers to the character/allele that is eclipsed by the dominant character, whereas a "dominant allele" is a character/allele whose phenotype is displayed to the complete exclusion of the other character/allele.
When a pair of alleles in a gene are homozygous, they are the same; when they are heterozygous, they are different.
