about the rate of cell division in cancerous tissue compared to the rate of cell division in normal tissue? What data did you use to answer this question? Answer: By comparing table 3 (normal cell tissue table) and table 4 (cancerous cell tissue table) I found that cancerous cell tissue has much faster rate of cell division. Specifically, I looked at the mitotic indexes on both tables and found that cancerous cell tissue actively divides at a much faster rate than normal cell tissue. 4. Which

“The difference between ordinary and extraordinary is just the little “extra”. (Anonymous)” Down-Syndrome is when there is an extra copy of the twenty-first chromosome in the human cell. This syndrome begins when a sex cell does not duplicate one of its chromosomes. When the egg and sperm unite, instead of having two copies of the twenty-first chromosome, there are three. The prenatal and postnatal development of a child with Down-Syndrome differs from the development of a child without a syndrome

cognitive impairment.The genetic disorder Down Syndrome is caused when abnormal cell division results in extra genetic material from chromosome 21. The most common form of Down syndrome is known as trisomy 21, a condition where individuals have 47 chromosomes in each cell instead of 46.This extra genetic material causes the developmental changes and physical features of Down Syndrome.Humans usually have 46 chromosomes in every cell, with 23 inherited from each parent. It's the most common genetic chromosomal

color the eyes are, what color the hair is, and also what gender you are when a baby. DNA is found in the nucleus of almost all cells. DNA also does something called replicating nucleotides. If DNA never replicated, cell life would be impossible. If this really were to happen, the cells would then die. DNA replicates itself in order to create more DNA strands for cells. It happens along the entire DNA molecule. It continues this until the entire strand/ladder

a prokaryotic and a eukaryotic cell. ANSWER: Prokaryotic and Eukaryotic organisms: are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane while membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The main different between the both cell organism is nucleus: Prokaryotic cells are smaller and simpler organisms without no nucleus but most are unicellular, while eukaryotic cells are larger organisms with a nucleus

Contemporary Right to the City When Henri Lefebvre first conceived of the right to the city in 1968, the Internet had not yet been invented; today, it is impossible to imagine a world without it. Advances in technology have allowed for dramatic improvements in the standard of living, and citizens in cities should have the right to realize these benefits. Singapore is striving to become a smart city, and has incorporated information and communication technology throughout the city that has resulted in

are about one hundred trillion of them in our bodies, each so small that several thousand could fit on the period at the end of this sentence. They make up all our tissues muscle, bone, blood which in turn make up our organs. Under the microscope, a cell looks a lot like a fried egg: It has a white (the cytoplasm) that’s full of water and proteins to keep it fed, and a yolk (the nucleus) that holds

birth defects, yet not everyone is equally susceptible. Birth defects are not merely a medical problem. They have profound effects on the social and psychological well being of their family and friends. In the normal course of fetal development, a cell migrates to their appropriate destination so that organs and limbs form where they should. Usually, the genes perform flawlessly, but mistakes can and do occur. Some of the most common birth defects results from the interaction between one or two abnormal

living organisms have a definite shape and size as well as physical and chemical composition inherited from their parents. This is possible because of a high degree of organization. The molecules of which an organism is made up are organized into cells, which in turn are organized into tissues, organs and organ systems making the whole individual. This kind of complex organization is not found in non-living things. Metabolism Green plants obtain their nourishment from the environment in the form
