When you have a plane determined by 3 points how do you calculate the normal vector? In summary, if you are given three points, you can take the cross product of the vectors between two pairs of points to determine a normal vector n. Pick one of the three points, and let a be the […]
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 […]

Which of the following is the weakest bond?
Which of the following is the weakest bond? (a) H-bond is only an interaction between electronegative element and hydrogen therefore, it is the weakest bond among all. Why is Bond making exothermic? Bond forming is an exothermic process, because it releases energy. In reaction profile diagram, the energy change in a reaction, is the difference […]
How does the angle of deviation depends on the refracting angle of the prism?
How does the angle of deviation depends on the refracting angle of the prism? The angle of deviation (δ) increases with the increase in the angle of prism (A). What is the angle of deviation when angle of incidence is 60? Answer. The angle of deviation will be 60° only. As refracted ray goes strainght […]
