broken into amino acids. This method suggests phagocytosis where the cell membrane completely surrounds a food particle[pic] Parasitic Nutrition is a mode of heterotrophic nutrition where an organism (known as a parasite) lives on the body surface or inside the body of another type of organism (known as a host). The parasite obtains nutrition directly from the body of the host. Since these parasites derive their nourishment from their host‚ this symbiotic interaction is often described as

Ecology Definitions Biogeography refers to geography in relation to living organisms. It studies the distribution of organisms’ geographically‚ and tries to understand the reason as to why a certain organism will prefer a certain locations compared to another. It then goes ahead to use the information discerned to describe what conditions favour different organisms. Abiotic Nonliving‚ as in abiotic factor‚ which is a nonliving physical and chemical attribute of a system‚ for example light

represents the smallest and least complex of all organisms. Through the process of mutation and adaptation they were able to survive to evolve into our modern day Bacteria‚ Archaea‚ Fungi and Protists. These post organisms have benefited from their early ancestor‚ by way of Endosymbiosis. Intricate protest and fungi are also able to use these genetic and chemical changes to their advantage and are very successful organisms. A prokaryote is a single celled organism that is lacking a nucleus‚ mitochondria

diffusion technique. The test measures the antimicrobial activity‚ by determining the smallest amount of agent necessary to inhibit the growth of a specific test organism‚ this value is the minimum inhibitory concentration (MIC). The MIC expresses the lowest concentration of agent that completely inhibits the growth of the test organism (Madigan‚ Martinko‚ Stahl‚ & Clark‚ 2012). The areas around the disks are the zone of inhibition‚ which are “proportional to the amount of antimicrobial agent added

Question 1 : The distribution of organisms in a community is affected by the biotic factors and abiotic factors. Abiotic factors are the non-living components in the ecosystem such as air‚ water‚ soil‚ temperature and light intensity. Biotic factors are the living components in the ecosystem such as animals and plants. In an ecosystem‚ the living organisms live together in their non-living environment and function as a unit. This dynamic system starts with species‚ populations‚ ecosystems‚ communities

Lab Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences

Around 4.6 billion years ago‚ our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern

two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The initial streak-plate procedure was performed and placed in the incubator at 37◦C for 24-48 hours. Upon observing the growth on this plate‚ it is fairly obvious that one of the organisms is Serratia
