What is survival of the fittest examples? In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs. Who […]
What are the two types of emission spectra?
What are the two types of emission spectra? The spectra can be divided into two types viz., emission and absorption spectra. The differences between them are given below. 1) The emission spectrum is obtained due to emission of radiation from the substances. What is most important about the emission spectra? The different colors of light […]
How many compounds can carbon form?
How many compounds can carbon form? The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things. Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or […]

Why are subtropical highs?
Why are subtropical highs? The warm air at the low latitudes rises and moves toward the poles. The rising air, and the subsequent clouds and precipitation, cause the tropics to be very wet. As the air moves towards the subtropics, it descends over the oceans and creates semi-permanent circulation features called subtropical highs. Where would […]

Is net force always 0?
Is net force always 0? When an object moves with constant velocity, the total net force on the object is always zero. If you have applied force, there’s another force (or, many forces) like friction to counterbalance it. Is normal force equal to mg? Normal force is equal to mg only when the object is […]
