What is the relation between the angle of incidence and the angle of deviation? The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation ‘d’. As the angle of incidence is increased, angle of deviation ‘d’ decreases and reaches minimum value. If the angle of incidence […]
How do the founder effect and bottlenecking differ?
How do the founder effect and bottlenecking differ? Bottlenecks and founder effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population’s size is reduced for at least one generation. A founder effect occurs when a new colony is started by a few members of the original […]
How is wind speed indicated what is the unit used to define wind speed?
How is wind speed indicated what is the unit used to define wind speed? How is Wind Speed and Direction measured? Wind speed is typically reported in miles per hour, knots, or meters per second. One mile per hour is equal to 0.45 meters per second, and 0.87 knots. Wind direction is typically reported in […]
What is an example of mutation in evolution?
What is an example of mutation in evolution? Even deleterious mutations can cause evolutionary change, especially in small populations, by removing individuals that might be carrying adaptive alleles at other genes. Figure 2: The history of the gray treefrog, Hyla versicolor, is an example of mutation and its potential effects. What is the most common […]
What bank angle is a rate 1 turn?
What bank angle is a rate 1 turn? The bank angle required to conduct a turn at a specific rate is directly proportional to True Airspeed (TAS). The approximate bank angle required to accomplish a coordinated rate one turn (3°/second) can be calculated by dividing the TAS (in knots) by 10 and then adding 7. […]

The following are some of the major schools of thought that have influenced our knowledge and understanding of psychology: Structuralism and Functionalism: Early Schools of Thought. Gestalt Psychology. The Behaviorist School of Thought in Psychology. The Psychoanalytic School of Thought. The Humanistic School of Thought. What are the […]
What are the 5 types of natural selection?
What are the 5 types of natural selection? Stabilizing selection, directional selection, diversifying selection, frequency -dependent selection, and sexual selection all contribute to the way natural selection can affect variation within a population. What is the rarest pattern of natural selection? The shape comes from the fact that both extremes are selected for during disruptive […]

How do astronomers identify stars?
How do astronomers identify stars? Thus, astronomers can identify what kinds of stuff are in stars from the lines they find in the star’s spectrum. This type of study is called spectroscopy. The science of spectroscopy is quite sophisticated. Why do stars wobble? We all know that the chains of gravity shackle a planet to […]
