    Characteristics can classify organisms into 5 key groups called the 5 kingdoms: - Protoctista: These are mainly unicellular organisms that also have a nucleus. Some examples of protoctista are paramecium, amoeba and unicellular algae. -Prokaryotes: These are also unicellular organisms like protoctista but unlike them, they do not have a nucleus. An example of a Prokaryote is bacteria. Some prokaryotes are able to make their own food which makes them more self-sufficient. These types of prokaryotes are called autotrophic. Although there are some that cannot produce their own food; this type of prokaryotes is called heterotrophic. -Fungi: Have no cell walls in their structure but they are multicellular. Fungi also don’t have chlorophyll, saprophytic feeders. Fungi are heterotrophic organisms therefore they are…

    A virus- a complex microscopic organism that possesses the ability to replicate inside the cells of a host. For centuries scientists have debated the topic of whether viruses are living organisms- or not. Viruses have been left in a “gray area”, becoming ignored in the study of evolution by scientists. When not in contact with a host, viruses tend to stray from the characteristics that define life. Characteristics such as the ability to respond to their environment, lack of cells, and the…

    Protists are expressed to be the first eukaryotic organisms. The reason they are considered to be the first is because they are organisms that don’t usually fit into natural grouping. However, protists are grouped together with either plants, animals, or fungi based on their characteristic that they mostly resemble. Protists are also cells with nuclei that can be classified in many different ways. The ways they can be classified are based on their feeding, reproduction, movement, and other…

    species on Earth. Living organisms exhibit unity because they use the same processes for seizing and storing energy, producing proteins, and passing on the information through genes from generation to generation. At the same time living organisms exhibit diversity because there are so many different species. All life on Earth is related because everything came to be from common origin yet beginning 4 billion years ago. Throughout the time living things have changed or evolved to fit different…

    All organisms derive from one common ancestor; however, the reason why organisms do not all look alike is because of evolution. When it comes to survival of the fittest it is all about who can adapt the quickest and evolve in order to keep the species alive. Two main factors come into play in evolution: abiotic and biotic factors. Organisms are constantly fighting abiotic forces such as weather. Weather or change of weather is one of the biggest reasons for organisms evolving. When the climate…

    was also discovered that fungi was a primary microorganisms accountable for the degradation of soil-buried polyester polyurethane (Barratt, Ennos, Greenhalgh, Robson, & Handley, 2003). Lastly, a recent discovery suggests that Methanogens, a simple organism, could survive life on Mars due to its anaerobic characteristics (University of Arkansas, 2015). After doing extensive research, we came to the conclusion that the most efficient way to test our hypothesis was to isolate pure colonies of four…

    Genetically modified organisms (GMOs) have become an increasingly popular option for nations that face a growing population and a limited food supply. GMOs are defined as an organism whose genome has been altered by the techniques of genetic engineering so that its DNA contains one or more genes not normally found there. This is typically accomplished through transgenesis, which is the usage of a bacterium to transfer DNA. Humans Altering DNA began, as Charles Darwin described, with selective…

    Researchers and scientists have now opened a new page in genetics called genetic engineering. With this new technology it has become possible to bypass the laws of nature that seem impossible to bypass. Evolution for instance, natures train tracks, you can’t get off of them without a catastrophe happening, or can you? Actually, scientist and researchers alike believe they can. How you ask? Genetically modified organisms, or GMOs. The odd thing about these GMOs is they are usually thought of as…

    1. Energy flows through an environment. What are two main sources of food? Why do organisms depend on food? Who or what is the primary producer in a food web? What do the arrows tell us about a food web? How would a food web change if an organism were removed? How can energy move through an environment? 2. Organisms and events cause environmental changes. How would an environment be affected by a change that harmed some hunted organisms but favored other hunted organisms? What are some…

    the world as the demand for food increases. Genetic modification is the use of biotechnology techniques to change the genes of an organism (AGRIC, 2015)
In Australia unless the Australian Gene Technology Regulator has concluded the Genetically Modified Organism, abbreviated as GMO is safe to human health as well as the environment it is not allowed to be handled. Other countries have similar regulators for GMO. 
Genetically engineering agricultural crops should be implemented as quickly as…
