Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division‚ from the original cell two cells are derived‚ each of which possesses the same genetic material. Mitosis has five phases: interphase‚ prophase‚ metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible

Physiology: the study of function (how the parts work) Levels of structural organization: There is a hierarchy of structural complexity‚ beginning with the simplest or chemical level and culminating with the highest level-the whole organism Chemical level – atoms (and their parts)‚ and combinations of atoms called molecures Cellular level – cells are the basic structural and functional units of life. Tissue level – tissue are groups of similar cells (and their intercellular

on the capital resources it uses which means the combination of debt and equity. This is given by the ratio return on capital employed (ROCE)‚ return on investment or accounting rate of return. This tells investors how successful the business is by analyzing the profitability. The higher ROCE‚ the more liable it is to carry a high return to the investors resulting in higher dividends and rising share prices. The profitability is important for businesses which want to attract financial funds

molecules move across the cell membrane is that the carbon dioxide molecules spread out rapidly out your red blood cells down their concentration gradient to your lungs. When water molecules move freely through your cell membrane is called osmosis as we learned last unit. The reason why molecules move across the cell membrane is because they are small molecules that have no charge like oxygen which the cell membrane need to survive. So basically the molecules that move across the cell membrane are

conditions do cells gain or lose water? Did water move into the cell or out of the cell while it was surrounded by hypotonic solution? The water moved into the cell‚ because there was less water inside the cell than outside (there were fewer water molecules inside). 2. In which direction did the water move though the cell membrane when the cell was surrounded by the hypertonic solution? The water moved out of the cell because there was a higher concentration of water inside the cell than outside

There are two processes of cell division that are very tricky. They are mitosis and meiosis. Many people often get confused with the two about their functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while

and mitosis are both types of cell division. Cell division is the reproduction of cells‚ and requires the duplication of chromosomes. Mitosis takes place when the nucleus divides. Meiosis is a type of cell division that produces haploid gametes in diploid organisms. Mitosis and meiosis are two very different processes. While meiosis only requires the cell to divide twice‚ the cell only divides once during mitosis. This causes meiosis to produce four cells and mitosis to produce two cells. Mitosis

memories occur when you recall an event that did not actually happen. Scientists have been conducting studies to determine whether false memories actually occur and how they occur. In 1995‚ Henry L. Roediger III and Kathleen McDermott constructed the now widely used Deese–Roediger–McDermott paradigm based on the procedure pioneered psychologist James Deese in 1959. They performed two experiments on 36 Rice University undergraduate students to determine whether false memories actually occur. They tested
