Genotype: The genetic makeup of a trait at each locus is called the genotype. A genotype usually consists of a pair of genes or alleles. Phenotype: The…
Data presentation is the process of showing the relationship between two or more datasets with the help of visual tools or aids.
n = speed in vacuum (or air) / speed in the medium. Air is about 1, water about 1.33, glass about 1.5. Larger n means slower light in that medium.
Static electricity can be useful when controlled.
Chemical bonds are the forces of attraction that hold atoms together. Depending on the tendency of an atom to lose, gain, or share electrons, there are…
Series resistors form a single current path.
Aromatic amines: toxic slogans, some historical industrial diseases named as history not a method. No smoking-and-amine chemistry. Medical help if exposure,…
Worked 4-mark primary succession: Bare rock no soil. Lichens/mosses as pioneers. Soil builds herbs then shrubs.
Search locates matching values; replace can alter many records and therefore needs narrow scope and backup.
Orbital: The region in space where the probability of finding an electron is maximum. Free Radical: An atom or molecule with an unpaired electron or…
Disinformation: Disinformation is false or misleading information that is deliberately spread to deceive people. Fake News: Fake news is false or…
Amplitude, period, frequency and phase are quantities used to describe the size and timing of an oscillation.
Convection transfers thermal energy through the bulk movement of a fluid.
|ax+b| = c with c>=0 splits into ax+b = c or ax+b = -c. If c<0, no solution. Inequalities: |x| < 2 is -2 < x < 2. |x| > 2 is x<-2 or x>2. Draw a number line.
Security and privacy are critical aspects of cloud computing. When using cloud services, whether for personal or business purposes, it is essential to…
Lipids are a group of biological molecules that include fats and oils and are important in energy storage, membranes and other biological functions.
Angular acceleration is the rate of change of angular velocity. For constant α, rotational kinematics equations mirror linear ones.
Redox reactions are reactions that involve simultaneous oxidation and reduction. Simple explanation: In a redox reaction, one substance is oxidized…
Add or subtract only when both matrices have the same order: combine matching entries. Scalar kA multiplies every entry by k. -A is (-1)A. These operations are…
Disorders of Immune System: Some conditions that stimulate a defective immune response or destroy immune system are called disorders of immune system.
The pituitary gland is a small, pea-sized endocrine gland attached to the hypothalamus at the base of the brain. It is called the master gland because…
<1,2,3>+<4,-1,0>=<5,1,3>. Parallelogram: diagonal is the sum. Subtract: a-b = a+(-b).
The Big Bang model describes the universe as having evolved from an extremely hot, dense early state and subsequently expanding and cooling.
