Can evolution be influenced by the starting population? Because evolution is slow, humans cannot influence it. Genetic drift only occurs in small populations. Humans are not currently evolving. How does the evolution of man develop? Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the […]
What are the 2 types of hardware?
What are the 2 types of hardware? Given below are the types of computer hardware: RAM. RAM (Random Access Memory) is a type of computer hardware that is used to store the information and then process that information. Hard disk. The hard disk is another type of computer hardware that is used to store the […]
What is the most common cause of a skid?
What is the most common cause of a skid? Combinations – skids are most often caused by excessive speed, coupled with too sharp a turn for the vehicle or braking when turning, or “normal” speed coupled with ice or snow or gravel on the road, etc. Hydroplaning takes place while driving on wet roads. Why […]
When 16 is added to a number the result is 40 What was the number?
What is the SI unit of temperature explain with suitable reason?
What is the SI unit of temperature explain with suitable reason? SI unit of temperature is Kelvin. Answer: The Kelvin (K) is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The temperature 0 K is commonly referred to as “absolute zero.” On the widely used Celsius temperature scale, water freezes […]

Why do compounds have chemical name?
Why do compounds have chemical name? The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning to what chemical compound the name refers. Each chemical name should refer to a single substance. What is the disadvantage of hydrogen peroxide? The main disadvantage is the small […]
Why do particles move in random motion?
Why do particles move in random motion? Particles in both liquids and gases (collectively called fluids) move randomly. They do this because they are bombarded by the other moving particles in the fluid. Larger particles can be moved by light, fast-moving molecules. Brownian motion is named after the botanist Robert Brown, who first observed this […]
What are the four main characteristics of NMR?
What are the four main characteristics of NMR? The principle of NMR usually involves three sequential steps: The alignment (polarization) of the magnetic nuclear spins in an applied, constant magnetic field B0. The perturbation of this alignment of the nuclear spins by a weak oscillating magnetic field, usually referred to as a radio-frequency (RF) pulse. […]
Why does increased branching lower boiling point?
Why does increased branching lower boiling point? Branching decreases the boiling point So the increase of surface area increases the ability of individual molecules to attract each other. Branching in molecules decreases the surface area thereby decreasing the attractive force between individual molecules. As a result, the boiling point decreases. What happens to boiling point […]
