1) Richard is remodeling his room. He wants to know which tile is the strongest and that will last the longest. To test the experiment, Richard will drop a 1lb rock, 2lb rock and a 6lb bowling ball. Whichever tile that breaks he will not use, and the most durable one, he will use. The independent variable is the durability and the dependent variable is the weight Richard will be putting one, since its changing. He starts with Tile Type One he first drop the 1lb rock, there is no visible crack.…

The Great Metabolic Race Ben Yu People are constantly going through a wide variety of chemical pathways and reactions to help them maintain consciousness. The pathways and reactions vary depending on one’s physical state and time. The metabolism of an athlete at the start of a race, after five minutes and after forty-five minutes can be observed, as the ratio of lipids and carbohydrates vary depending on the time of the race. Due to the different energy densities and the body’s varying…

It consists of several major pathways including glycolysis, pyruvate oxidation, the citric acid cycle and finally the electron chain transport. Glycolysis is a multi-step pathway that occurs in the cytoplasm of the cell where one glucose molecule is broken down into two pyruvate molecules. Glycolysis produces 4 ATP’s and 2 NADH. It uses 2 ATP’s in the process for a net…

on the size of the electron cloud surrounding the inner nucleus. As one moves across a period, the atomic radius is smaller. In other words, when one moves across the periodic table from left to right, the atomic radius gets smaller. This is because there is increased attraction which makes the atom smaller. As one moves down the periodic table with increased principal quantum number, the atomic radius gets larger. This is because the average distance of the valence electrons from the nucleus…

paramagnetic materials are caused by unpaired electron pairs. Electrons are found in pairs most of the time, when they are paired and the electrons are circling the nucleus in opposing directions, they cancel each other out and therefore no magnetic reaction happens. When there are unpaired electrons, they may have a reaction to external magnetic fields, the reaction can be categorized as diamagnetic, ferromagnetic, or paramagnetic. In diamagnetism, all the electrons are paired, but they do…

carbon atoms. A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds. This makes diamond's melting point and boiling point very high.There are no free electrons or ions in diamond, so it does not conduct…

Animal Behavior Objectives Define fixed action patterns and give an example. Fixed action patterns (FAP) are innate behavioral sequences of an individual within a species that consistently displays these sequences with a regular pattern of behaviors carried out to completion. These behaviors are prompted by a “releaser,” which is a specific sign stimulus. This prevents energy waste within the individual, and hence the species. An example of a fixed action behavior is a female turkey’s mothering…

attraction between shared pairs of electrons, another example is of a giant covalent bond. A giant covalent bond is held in a giant molecular lattice structure. (See diagram B below.) B) s-cool (2016) This giant structure is made of strong covalent bonds, so to break these bonds it takes a lot of energy,(OCR 2008) this results in the melting and boiling points of a giant covalent bond being extremely high to overcome the strong electrostatic force between the electrons.…

He discovered the electron through a series of experiments. The experiments were designed to study the nature of the electric discharge in a high-vacuum cathode ray tube. As thomson conducted the experiment he noticed some anomalies. He interpreted the anomalies as the evidence of smaller bodies that are far smaller than the atom. The discovery of the atom had drastic impacts on the world. The discovery led to a better understanding that electrons are important for the bonding of the…

carbon dioxide and six molecules of water. “The overall chemical reaction for cellular respiration is… “C6H12O6 + 6O2 → 6CO2 + 6H2O” (“CK-12 Foundation”). Cellular respiration can be broken down into three stages: glycolysis, krebs cycle, and the electron transport chain. Stage one of cellular respiration is glycolysis. Glycolysis is the splitting of glucose. “Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. In the process, two molecules of…
