Answer:
True
Explanation:
The Modern Synthesis is also called the Neo-Darwinian theory as it explains the fusion of Mendelian genetics with Darwinian evolution into a singular theory of evolution. It is sometimes referred to as the Neo-Darwinian theory.
It refers to evolution as "changes in allele frequencies within populations," in order to explain the genetic basis of evolution. The random genetic drift, gene flow, mutation pressure, and natural selection are seen to cause changes in allele frequencies. Resulting in several differences that can be seen gradually over a particular period in time.
In the Modern Synthesis, mechanisms of evolution and not natural selection takes a major role and it explains the continuance of genetic variation going along with Gregor Mendel's particulate theory of inheritance, where the alleles of a gene remain as individual entities rather than merging.
The major key players of the Modern Synthesis are R. A. Fisher and Sewall Wright (worked on population genetics), Theodosius Dobzhansky (studied the fruitfly Drosophila), Ernst Mayr (models of how speciation occurs), George Gaylord Simpson (introduced paleontological observations into Modern Synthesis) and G. Ledyard Stebbins (added some principles as a result of his botanical studies).
Answer:
The direction of motion is changing, so the car is accelerating. By Newton's second law, an unbalanced force must be acting on the car if it is accelerating.
Answer:
The correct answer is option D, that is, the elephant will not react.
Explanation:
A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.
In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
