BIO - Essay Example Additionally, Barbara developed theories the suppression and expression of genetic information across generations. Walter Sutton greatly contributed to the theory of evolution. Sutton believed that it was possible to apply the Mendelian laws of inheritance to chromosomes at cellular level of living organisations (Lynch, Jay, and Derek 56). This led to the creation of Boveri-Sutton chromosome theory. This theory posits that chromosomes are the carriers of genetic materials. Walter Sutton, the proponent of this theory, believed that chromosomes are found in all dividing cells and are transmitted from generation to generation, thus forming the bases of inheritance. Herman Muller concentrated on the study of physiological and genetic impacts of radiation. According to Herman, radioactive fallout originating from nuclear war and nuclear testing posed a great risk the genetic make-up of living cells (Lynch, Jay, and Derek 11). Herman revealed that there was a cross correlation between radiation and lethal mutations, which were responsible for altering biological traits in populations. Correnââ¬â¢s primary focus was on botany and genetics. He independently discovered the principles of heredity, which contributes to evolution and natural selection. Corren restated Mendelââ¬â¢s results including his law of independent assortment and law of segregation. These are the fundamental laws used for understanding natural

The story of an hour by Kate Chopin Research Paper
The story of an hour by Kate Chopin - Research Paper Example mmediate duty to grieve over her husbandââ¬â¢s death as depicted in the line ââ¬Å"She wept at once, with sudden, wild abandonment, in her sisterââ¬â¢s arms.â⬠Mrs. Mallard, however, escapes the face of agony right away upon entry to her room, as though it were a private world of all unseen hopes. Apparently, the room represents another dimension consisting of objects that symbolize what Mrs. Mallard has long yearned for and Chopin illustrates this in the phrases ââ¬Å"new spring lifeâ⬠, ââ¬Å"delicious breath of rainâ⬠, and ââ¬Å"countless sparrowsâ⬠twittering. While part of her consciousness has fully absorbed the thought that she is expected to mourn for a major loss, she is being spontaneously consumed by something that makes her exclaim ââ¬Å"free, free, free!â⬠and ââ¬Å"Free! Body and soul free!â⬠in a rather cautious mumbling gesture which is altogether understood by herself alone. In that realm, the moment of illumination leads the widow to cherish mixed conflicting emotions where she obtains a sense of certainty toward a much desired fate ââ¬â the return to singlehood and freedom. Chopin proceeds to enumerate the attributes that recollect the state of youth of Mrs. Mallard, stating ââ¬Å"She was young with a fair, calm face, whose lines bespoke repression and even a certain strength.â⬠These details may be claimed as necessary in order for the character of Louise to emerge out of Mrs. Mallard and exhibit some sharper manifestation of hope for liberation despite lack of concrete evidences to support the idea that the passing away of Brently amounts to the happiness of Louise. This hope eventually shatters when Mr. Mallard comes back alive, contrary to the previous belief, so that his presence causes the irony of his wifeââ¬â¢s diagnosis where ââ¬Å"the joy that killsâ⬠is actually a metaphor that means ââ¬Å"the joy that has been killed.â⬠Women of the 1800s lived in societies that were sexist by nature.
