Organic compounds can be represented using different types of formulas, including empirical, molecular, structural, displayed, condensed and skeletal formulas,…
The nitrogen cycle is the natural circulation and transformation of nitrogen between the atmosphere, soil, living organisms and decomposing matter.
Unstable Equilibrium is a state in which a body, when slightly displaced and then released, moves further away from its original position. Key…
Energy Cycle: A diagrammatic representation of the energy changes involved in a process, based on Hess's Law. Enthalpy of Solution (ΔH_solution): The…
An average locates the data with one number. The mean is the balancing point. The unit symbol is x-bar (read 'x bar') for the mean. For ungrouped data, x-bar =…
Lanthanides Lanthanides, also known as "rare earth elements", are a series of 14 elements located at the bottom of the periodic table. They…
A vector carries foreign DNA into a host. Plasmids are common bacterial vectors containing an origin of replication, selectable marker and cloning site.
(x-2)(x-5)>=0 includes 2 and 5: (-inf,2] U [5, inf) if a>0. A square bracket is a filled circle. Round is open.
The nephron is the structural and functional unit of the kidney. Each kidney, in a human, contains about one million nephrons.
Quantum computers use qubits and quantum principles such as superposition and entanglement. They are not simply faster versions of classical computers for…
A non-ideal or real gas is a gas whose behaviour differs appreciably from the ideal-gas model because molecular size and intermolecular interactions can no…
Circulation of blood is the continuous movement of blood through the heart and blood vessels, delivering oxygen and nutrients to tissues and removing…
Bone is a living tissue that undergoes repair following fracture. The repair process of a simple fracture takes place in four major steps. Haematoma or…
Vaccines present safe antigenic material that creates immune memory, reducing disease risk and transmission without requiring the full disease.
Properties of Liquids: The characteristic behaviour of liquids in terms of diffusion, compression, expansion, motion of molecules, spaces between…
Electromagnetic waves are widely used to carry information.
Magnetic Recording is a method of saving sounds, pictures, and data in the form of electrical signals by the process of selective magnetization of portions…
Polymers: Polymers are large molecules built from many smaller repeating units called monomers. Monomers: Monomers are small molecules that bond…
Search locates matching values; replace can alter many records and therefore needs narrow scope and backup.
The reverse: sin C + sin D = 2 sin(C+D2) cos(C-D2). sin C - sin D = 2 cos(C+D2) sin(C-D2). cos C + cos D = 2 cos(C+D2) cos(C-D2). cos C - cos…
Bioremediation is the process of using living organisms, especially microorganisms including bacteria, fungi, and plants, to clean up the environment…
If two beta-hydrogens, two alkenes. More substituted major (named rule). Cis-trans if the alkene allows. Not a rubber-plant. Bulky base and heat push…
A trig equation usually has infinitely many solutions; state the interval or give a periodic family.
Artificial Intelligence (AI) is based on creating intelligent systems that can perform tasks that normally require human intelligence. Machine Learning…
