2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons…

The earth as an organism has been a popular topic over the last hundreds of years throughout science. However, James Lovelock’s approach of the earth was, and still is, an extremely controversial concept among scholars. He describes his theory as, “A complex entity involving the Earth’s biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet” (148). In other words, the…

Charles J. Epstein was a highly regarded geneticist who made tremendous contributions to the medical field during his lifetime. He was born on September 3, 1933 in Philadelphia, Pennsylvania to Jacob C. Epstein and Frieda Epstein, Jewish immigrants from the Ukraine. During his high school years at Central High School, he excelled at academics and enjoyed track and field, and played the cello. After completing high school he went on to Harvard College where he graduated summa cum laude and…

Charles Darwin is a scientist that came up with the theory of natural selection to explain variation and evolution. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype (Zimmer&Emlen, 2013). This means that in an environment where the condition is constantly changing, species that stay in that environment and use it as their habitat adapt to the changes of the environment to survive the changes and their off springs are also able to…

If both parents have alcoholism, will their children have alcoholism, too (nature vs nurture)? If both parents have alcoholism, it does not necessarily mean that their children will have alcoholism. Inherited biochemistry affects alcohol metabolism. There is no specific gene for alcoholism. However, the alleles that make alcoholism have been identified on every chromosome except the Y. Each individual is different, they're reaction to alcohol may be different from others. Both parents metabolism…

Human development has been regarded as one of the most highly controversial topics in the world of psychology. Nature vs Nurture is labeled as a debate. Nature and nurture has to do with behavior, feelings, personality, and intelligence. Many that believe we inherit our personalities, feelings, behavior and intelligence are on the nature side. Others who think its environmental influenced are on the nurture side. Nature and nurture goes hand and hand in the development of the human process.…

Proposed research: Aims and Objectives: Aim1: To address the roles of the Hira complex in rRNA transcription and embryonic development Aim2: To characterise rDNA chromatin organisation in the oocyte Aim3: To elucidate the transcriptional machinery of RNA Polymerase I in the oocyte Experimental Approach: Aim1: To address the roles of the Hira complex in rRNA transcription and embryonic development The Hira histone chaperone complex is an evolutionarily conserved complex, which is composed of…

Observation of mitosis in Onion root tips Answer the following question to its full explanation: 1. What is Cytokinesis? Compare and contrast cytokinesis between plant and animal cells. Cytokinesis is the last step in cell division, where the cytoplasm divide and the two daughter cells appear. In Animals, the cytokinesis processes occurs through cleavage. Firstly, in the old metaphase plate position, a cleavage furrow is formed. On each sides of the furrow, a contractile ring formed of actin…

Background Hidradenitis Suppurativa is a genetic condition that causes lumps under the skin, acne-like pustules, and deep scarring. (1) With time, the lumps will rupture, causing pus, and fluid to drain from these. (3) This condition tends to appear in teens and in early adulthood. These lumps and acne-like pustules tend to appear in the armpit, groin, nape of the neck, waist, inner thighs, and buttocks. (3)It is a rare condition, with the rarest of presentations of the lumps are in the area…

Proteins are large, complex molecules found throughout the body. They are polymers made out of different types of small unites called amino acids. Each amino acid consists of a central carbon atom, which is attached to a hydrogen atom, an amino group, a carboxyl group, and a unique side chain or R group. There are twenty different types of amino acids and each one of them has different chemical properties. Amino acids are held together by covalent peptide bonds therefore the proteins, chains of…
