Repeated presentations of the CS without UCS lead to extinction of CR. During acquisition, CS is paired with UCS, learning occurs. Discrimination occurs when organism learns to respond to stimulus but not to another, stimulus generalization occurs when it responds to stimuli.

In classical conditioning, an unconditioned stimulus (UCS) elicits an unconditioned response (UCR) without prior learning. The conditioned stimulus (CS) is a neutral stimulus that acquires the capacity to elicit a response through association with the UCS. The response that is elicited by the CS is called the conditioned response (CR).

Repeated presentations of the conditioned stimulus without the unconditioned stimulus lead to the extinction of the conditioned response. This occurs when the CS is no longer followed by the UCS, and the CR eventually disappears.

Acquisition refers to the initial stage of learning when the CS is first paired with the UCS. During acquisition, the CS is presented before the UCS, and the two stimuli are paired several times. As a result of this pairing, the CS begins to elicit the CR, and learning occurs.

Discrimination is the ability to distinguish between similar stimuli and respond differently to each of them. Discrimination occurs when an organism learns to respond to one CS but not to another, even though both stimuli may be similar.

Generalization is the tendency to respond to stimuli that are similar to the CS. Stimulus generalization occurs when the CR is elicited by stimuli that are similar to the CS, even though they have not been paired with the UCS.

Backward conditioning occurs when the UCS is presented before the CS, which results in little or no learning. This is because the UCS is presented before the CS, and there is no contingency between the two stimuli.

Answer:The speed, wavelength, and frequency of a wave are related by mathematical formula, speed = wavelength times formula. What happens to the speed of a wave if the medium, temperature, and pressure do not change. The speed of the wave remains constant if the medium, temperature, and pressure don not change.

Explanation:

If the medium, temperature, and pressure do not change, the speed of a wave remains constant.

A wave speed constant refers to the fixed velocity at which a wave travels through a specific medium, under certain conditions of temperature and pressure. It is a characteristic property of a given type of wave and is determined by the properties of the medium through which the wave is traveling.

The wave speed constant is also known as the phase velocity, as it is the velocity of the individual wavefronts of the wave, rather than the velocity of the energy or particles that make up the wave.

The function of a tRNA molecule is to recognize the appropriate anticodons in mRNA.

The transfer RNA (tRNA) is a type of RNA molecule that plays an important role in translation. Its primary function is to carry amino acids to ribosomes during protein synthesis, where the amino acids are linked together to form proteins.

The tRNA molecule contains an anticodon sequence that matches a specific codon on the messenger RNA (mRNA) molecule.

The anticodon is a sequence of three nucleotides that are complementary to a specific codon in mRNA.

The anticodon is located at the end of the tRNA molecule opposite the amino acid attachment site. The anticodon base-pairs with the codon on the mRNA during translation, which ensures that the correct amino acid is added to the growing polypeptide chain.

Prokaryotic cells use structures called flagella to move and Eukaryotic cells use structures called cilia and pseudopodia for movement.

Prokaryotic and eukaryotic cells that are able to move, use different structures for motility.

Prokaryotic cells, such as bacteria, use structures called flagella to move. Flagella are long, whip-like structures that protrude from the cell and rotate to propel the cell forward. Some prokaryotic cells also have pili, which are shorter, hair-like structures that can help the cell move across surfaces.

Eukaryotic cells, on the other hand, use structures called cilia and pseudopodia for movement. Cilia are short, hair-like structures that beat in a coordinated fashion to move the cell or substances across the cell's surface.

Pseudopodia, also known as "false feet," are temporary extensions of the cell's cytoplasm that can be used for movement or to engulf food particles.

When the surface area is lost due to

emphysema, pulmonary gas exchange

problems are expected to occur

A kind of chLronic obstructive pulmonary disease (COPD) known as emphysema causes damage to the alveoli in the lungs, reducing the surface area available for gas exchange.

Due to this injury, hypoxemia (low levels of oxygen in the blood) and hypercapnia (high levels of carbon dioxide in the blood) may arise from the lungs' inability to exchange oxygen and carbon dioxide with the bloodstream.

Therefore, none of the suggested answers to the question are correct. Normal breathing (eupnea), over-breathing (hyperventilation), and hypocapnia (low levels of carbon dioxide in the blood) are not frequently linked to emphysema but rather to other diseases or physiological states.

Alleles are often described as being either dominant or recessive. The characteristic of recessive alleles that usually makes them 'recessive' is that the effects of the recessive allele can only be observed when two copies of it are present in an individual.

A recessive allele refers to a genetic trait that only expresses itself when there is no dominant allele present. When both alleles are recessive, the individual will show the trait associated with the recessive allele.

The dominant allele is represented by a capital letter (e.g., B), whereas the recessive allele is represented by a lowercase letter (e.g., b). The genotype of a dominant trait is indicated by two capital letters (BB), whereas the genotype of a recessive trait is indicated by two lowercase letters (bb).A dominant allele only needs one copy to be expressed, while a recessive allele needs two copies. An individual can only express a recessive trait if both copies of the gene are the recessive form. If an individual has one dominant and one recessive allele, they will show the dominant trait, which is why recessive alleles are often hidden or masked by the presence of a dominant allele.

Answer:

They create a Mountain Peak

When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.

A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.

When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.
