Organism

explains that in his high school biology class he was taught how to separate living and non-living things. First, he says that a living thing respires, meaning that it uses oxygen. But the use of oxygen for function is not exclusive to only "living " organisms. He explains that his bike also requires oxygen which is then burnt up in the cylinders. This is true, because oxygen plays a similar role in the bike as it does in the human body…

are cells that do not have membrane bound organelles, such as ribosomes and include organisms such as bacteria. In contrast, eukaryotic cells contains organelles and are often more complex organisms (Karp, 2010). These cells have some similar features such as the plasma membrane and the use of ribosomes to make proteins. However, there are also significant differences between prokaryotic and eukaryotic organisms. Whilst the prokaryotic/ eukaryotic classification system is useful, it has to be…

food we eat has evolved to cope with the organisms that eat it, and we’ve evolved to cope with that. We’ve looked at the way we’ve evolved to resist or manage the threat posed by specific infectious diseases, like malaria… At the end of the day, every living thing–bacteria, protozoa, lions, tigers, bears, and your baby brother–shares two hardwired imperatives: Survive. Reproduce.” (Chapter 5- Of Microbes and Men) Enduring Understanding: 1.B All organisms…

Metabolism is a complex process in organisms that convert the food into energy for organism to function properly. Metabolic rate is typically defined as the amount of energy the organism is currently using to maintain the activity (Perkin, 2015). Since metabolism is a key in sustaining the organisms’ life, we decided to investigate the experiment about metabolic rate caterpillar, Manduca sexta. There are many techniques used to measuring the metabolic rate, but there are only best method that…

Hughes says, “Does it dry up”, (Hughes 2) which creates the image of a dream being a living organism or the beholders themselves. The first idea that comes to mind would be that the organisms lose their moisture or water and become small and withered representing the life of the dream being drained. This line makes the reader think of deserts and summer and heat. This also creates the idea…

The definition of Symbiosis is "the living together in an intimate association of two or more dissimilar organisms". Symbiosis is a crucial part of our existence and a reason for the beginning of life on this planet we call home. According to history of our planet, Earth was formed from absolute nothingness to tiny molecules of thick water vapor and many compounds of nitrogen, carbon dioxide, ammonia, and more. From these molecules, the disorder and order of the molecule reacted with each other,…

origin of functional molecules and cells. What is meant by “emergent properties” in biology? In biology, emergent properties are when parts of an organism interact with one another to perform a specific function. It is important to note that an emergent property is not exhibited by one part alone. Usually, emergent properties arise when a part of an organism becomes part of a bigger system. For example, on their own Hydrogen, Oxygen, and Nitrogen cannot produce macromolecules, but when they are…

ting who organisms will mate with, as shown in the paragraphs Sniffling out a mate, and Fly Perfume. With the ability that bacteria has on mating, it is possible to extend and create a whole new species. When it comes to mating, organisms usually prefer to mate with an organism similar to them. The author believes that a major change with a species could happen because of preference, and natural boundaries. One example of this can be found on page five, “Over time, two isolated groups of a…

tools. Caenorhabditis elegans, is a free-living, non-parasitic soil nematode that can be safely uded in the laboratory and is common around the world.What is unique to this organism is that wild-type individuals contain a constant 959 cells. The position of cells is constant as is the…

Consequences of biodiversity loss Biodiversity is a phenomenon that all life on earth depends on. It is the link between all life on earth. In other words the web of life. There is a perfect interdependent system in place that allows every organism on earth what it needs needed to survive and the relationship between all is beneficial to all others, except in most cases humans. We have more of a symbiotic relationship with the earth and everything else on it where we could be seen as kind of…
