Does random mating affect evolution? Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. A single generation of random mating will restore genetic equilibrium if no other evolutionary mechanism is operating on the population. What is the result of assortative mating? Assortative mating is the tendency […]
Which one of the following can be polarized?
Which one of the following can be polarized? Example electromagnetic waves. Hence, X rays can be polarised. Sound waves in air travel parallel to the direction that the particles within it oscillate it therefore they are longitudinal in nature – it propagates in 1 dimensional direction so it can not be polarized. Can heat waves […]
Are extrasolar planets rare?
Are extrasolar planets rare? It’s pretty rare for astronomers to see an exoplanet through their telescopes the way you might see Saturn through a telescope from Earth. That’s called direct imaging, and only a handful of exoplanets have been found this way (and these tend to be young gas giant planets orbiting very far from […]

Why do astronomers place telescopes in Earth orbit?
Why do astronomers place telescopes in Earth orbit? Astronomers place telescopes in Earth orbit in order to observe radiation from those parts of the EM spectrum for which the atmosphere would normally absorb or significantly scatter that radiation. What type of waves can we use to explore space? Telescopes Optical telescopes observe visible light from […]
What color that makes Brown?
What color that makes Brown? Brown is a composite color. In the CMYK color model used in printing or painting, brown is made by combining red, black, and yellow, or red, yellow, and blue.

Is Pluto seismically active?
Is Pluto seismically active? You don’t have to be a planet to have tectonics: Pluto is currently geologically active. Data from NASA’s New Horizons spacecraft when it flew through the Pluto system in 2014 revealed a complex set of geological features, including faults. Why is Pluto active? Pluto may still be tectonically active because that […]
Is body size a life history trait?
Is body size a life history trait? Some life history traits include the size of an animal at birth (or at hatching), the age and size at which an animal reaches reproductive maturity, how it reproduces (oviparous or viviparous), how often it can reproduce (semelparous or iteroparous), the length of time it is reproductively active, […]
