VSEPR Theory in Drug Design: The application of Valence Shell Electron Pair Repulsion theory to predict the three-dimensional shapes of drug molecules,…
The acceleration due to gravity at Earth’s surface is the acceleration a freely falling object experiences due to Earth’s gravitational field.
Python is a high-level, object-oriented (data-driven), and human-friendly (easier to grasp) computer programming language. In simple words, Python is a…
Plant and animal cells share a common basic structure but differ significantly due to the presence of the cell wall in plants. This difference gives each cell…
Eye focuses on retina; myopia uses concave correction, hypermetropia uses convex correction.
A transistor can switch between low- and high-conduction states or amplify signals. Output energy comes from the external supply, not from the transistor…
f is even if f(-x)=f(x), odd if f(-x)=-f(x); otherwise it is neither.
To perform an acid-base titration, it is necessary to choose the correct indicator. For an acid-base titration, choose an indicator whose pH range is within…
sin(360-A)=-sin A, cos(360-A)=cos A. sin(-A)=-sin A (odd), cos(-A)=cos A (even). sin(270-A)=-cos A, and the rest as the book table. Meaning: even/odd plus CAST…
n1 sin i = n2 sin r, with i and r from the normal. From air into glass: sin i / sin r = n_glass. Frequency stays the same; wavelength and speed drop in the…
A point dividing a line segment in a given ratio is found by a weighted average of the endpoint coordinates.
If two lines have slopes m1 and m2, the tangent of the angle theta between them is |m2-m11+m1 m2| when 1+m1 m2 != 0. If 1+m1 m2 = 0 they are perpendicular…
Quadrat for plants: random, several, mean x area. Mark-recapture assumptions fail if marks harm or animals learn traps. These are exam methods in words, not a…
The nitrogen cycle is the natural circulation and transformation of nitrogen between the atmosphere, soil, living organisms and decomposing matter.
Combustion of Alcohols: The burning of alcohols in the presence of oxygen to produce carbon dioxide, water, and heat. In simple words: Alcohols burn in…
Expressions in controls produce row calculations, group totals, grand totals, dates, and page numbers.
Sex determination means that a newborn would be a male baby like father or female baby like the mother. The mechanism of sex determination in humans is…
Earth's atmosphere is the envelope of gases surrounding the planet. It is divided into different layers mainly on the basis of changes in temperature with…
1. Diffusion: · Diffusion depends on velocity of molecules. · Movement of molecules in solids is vibration only, and they show negligible diffusion.…
An operating system (OS) is essential software that manages a computer's memory, processes, hardware, and software, enabling user interaction. It loads…
Secretin: Secretin is a hormone produced by the endocrine cells (S cells) in the walls of the duodenum. It is released in response to acidic chyme entering…
OH- -> alcohol. CN- -> nitrile (then hydrolyse to acid named later). NH3 -> amine (later chapter). AgNO3 ethanol: halide test speed (3 fastest ppt school).…
Many diseases cause degeneration in different part of the nervous system without an identifiable external cause. · Genetic factors are known to be involved.…
Hooke's Law states that within the elastic limit, the extension (or compression) of an elastic object is directly proportional to the applied force (or the…
