Are Viruses Alive? For years‚ scientists debated whether or not viruses are living organisms. The most confusing thing about viruses is that they display characteristics of both living and nonliving beings (Lourerio‚ 2006). Even after years of research and argument‚ we have not come to a final conclusion to this mind boggling question: Are viruses alive? Viruses are miniscule parasites that spread infection through all species of living things‚ plants and animals. Parasites are completely dependent

Unit 2 Assignment Critical Thinking 1. Explain why‚ even under ideal conditions‚ Streptococcus grows slowly. Cellular respiration is a process in which glucose is broken down to form an energy that can be used by the cell. There is aerobic respiration and there is anaerobic respiration. Aerobic respiration involves a series of chemical reactions in which oxygen is used to transform into carbon dioxide and H2O. This process generates energy carrying molecules called ATP. Anaerobic respiration

debate about whether viruses are alive or not. Viruses are what makes you sick such as Influenza‚ Ebola‚ HIV‚ Mumps‚ and the common cold. Some scientists argue that viruses are not alive. Yet‚ there have been some new studies that show that viruses may in fact be alive. After finding out the facts‚ you can decide if viruses are living. Many scientists are more willing to accept the theory that viruses are not alive. The main piece of evidence that supports this theory is that viruses can not reproduce

Viruses can infect all types of cells including plant‚ animal‚ protozoa‚ fungi‚ and bacteria. Virus composition is unique and does not resemble a living cell because they only contain the necessary parts to enter and leave an infected cell. A virus is a minute parasite (10 to 100 times smaller than bacteria) that is unable to reproduce by itself; however‚ once it infects a vulnerable cell a virus can make the cell’s inner workings produce viruses on its behalf. Viruses typically have either RNA

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped
