Are Viruses Alive? 1. Describe how a virus differs from bacteria. Most Viruses are harmful and their only purpose is to invade a host cell‚ reproduce and destroy the host cell in the process. Close to 99% of bacteria are beneficial with only a few that cause diseases. Life on earth could not exist without bacteria. Bacteria produce nearly half of the oxygen found in the atmosphere. Viruses have no cells‚ nucleus‚ cytoplasm or cell membrane. Viruses consist of tiny particles of nucleic acid

My “Whale” to Survive Why do you think any living animal wants to keep living‚ to keep going on? Why do living organisms try so hard to survive? The very idea of just thinking about why organisms and more specifically‚ humans go on living is bewildering. The survival instinct theory states that all organisms have biological tendencies that help them survive. This implies that all behaviors and actions are based on the survival of the individual organism. Therefore‚ based on science‚ I believe that

What’s the difference between living and existing? Some people are incredibly naïve thinking that living and existing are the same thing. Anyone can exist‚ but it’s not the same as to live. Existing is simply giving in‚ not controlling your own life‚ but letting everything around control you; just accepting and not in a good way; just not caring where the next path will take you and not doing anything about it. Meaning you’re just a waste of time and space‚ you’re not in control and you’re not

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

Students also struggle to understand the phases of each cell division and the reason they occur. Mitosis and meiosis are important to understand and several differences are evident between them which include the type of cell division‚ the genetic makeup of the cells‚ and the function of the cells. However‚ similarities do exist between mitosis and

Aim: To investigate whether living organisms by respiration convert oxygen into Co2. Introduction: The process by which organisms release energy from food is called respiration. There are two categories of respiration‚ depending on the amount of oxygen available. Aerobic respiration is the most common type of respiration. It requires oxygen- the reason why you are breathing right now. Anaerobic respiration requires no oxygen. The experiment which will take place is the aerobic respiration. Earthworms
