trial and error
The apparently random, haphazard, hit-or-miss exploratory activity which often precedes the acquisition of new information or adjustments; it may be overt, as in a rat running in a maze, or covert (vicarious), as when one thinks of various ways of coping with a situation.
Illusions are the perceptions and sensory data obtained from situations in which human error prevents us from seeing the real deal. Learn more information on illusions and mind trickery in this tutorial...
Gregor Mendel's studies into Monohybrid and Dihybrid crossing and Charles Darwin's study of evolution and natural selection have led to studies that actively manipulate the phenotype of offspring by selective breeding in animals and plants. ..
Homeostasis is the relatively stable conditions of the internal environment that result from compensatory regulatory responses performed by homeostatic control systems. Know the different components of homeostatic control systems, homeostatic regulators, and the various biological processes that homeostasis entail...
Gregor Mendel, an Austrian monk, is most famous in this field for his study of the phenotype of pea plants, including the shape of the peas on the pea plants. Know the works of Mendel that set the foundation of genetics. ..
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
This tutorial looks at the mutation at the gene level and the harm it may bring. Learn about single nucleotide polymorphisms, temperature-sensitive mutations, indels, trinucleotide repeat expansions, and gene duplication...
