Organisms

Scientific experiments and observations have led to many discoveries, which in turn have allowed scientists to develop a better understanding on the way diseases originate in humans. Molecular biology in particular has allowed scientists to discover the way in which domains, found in proteins impact a genome. Domains are autonomous folding units that carry out specific functions and mechanisms in a certain protein. These functions consist of being responsible for interactions in the cell, which…

you have more than two sets of chromosomes. As polyploidy is somewhat confusing, there is two articles of explanation on this subject. I want to start by explaining gene doubling in an easier sense due to its confusion. Polyploidy can occur when organisms self-fertilize or through sexual reproduction. Through research, it's said that this process can possibly create a new species after being done. Although, scientists did not realize the importance that this process had for plant evolution. …

species of dinosaurs. Lastly, the embryo that develop as a result of the division of cells needs to be inserted into the eggs since the dinosaurs were born through eggs. The plastic egg created in the Jurassic Park movie cannot perfectly work as every organism has…

A dichotomous key and observation can be useful tools in identifying microorganism’s taxonomy as a mold, yeast or bacteria. Microbes can be found everywhere in cold, warm, moist or dry environments and molds, yeast and bacteria each have unique characteristics that set them apart from one another and allow them to survive in these environments. Through macro and microscopic observation, different microbes can be observed through the natural liquid and solid phases and be made into slides to be…

The symbiosome is a key area of research at present, it is defined as the organ which the organism produces to entrap the microbe internally* (V. Clarke et al 2014). The symbiotic relationship between plants and fungi is an essential one for benefiting fully from Mycorrhizae, which then helps the land plants absorb the essential nutrients such as phosphorus and nitrogen. The interaction between plants and microbes allows for essential functions of the plants such as growth, germination and…

as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and unification of two or many beings entering into symbiosis.” The Encyclopedia Britannica defines endosymbiosis as a theory in which modern organelles such as mitochondria and chloroplasts are descended from bacteria…

internalize particles (>0.5um) whereas internalization of fluids through micropinocytosis mechanisms or solute into vesicles for size less than (<0.5) Phagocytosis is a ubiquitous process throughout nature. The behavior can be observed in unicellular organisms like amoeba using phagocytosis to obtain nutrients. Similarly, for vertebrates phagocytosis is an efficient method used by phagocytic cells such as macrophages, dendritic cells, and neutrophils to uptake, eliminate pathogens and…

The purpose of this report is to investigate the following observations; Euglena is a unicellular organism in the kingdom of Protista, the cells are both autotrophic and heterotrophic which means if there is no food source but there is a light source they will fall on their autotroph tendencies through photosynthesis while if there is a food source but no true light source they will fall on their heterotroph tendencies. Euglenas show positive photo-taxis due to their ability to preform…

The benefits and risks of the scientific method of genetically modifying crop species Since the emergence of agriculture over 10,000 years ago, humans have been altering the genomes of the crops they produce in order to increase the crop quality in many ways, with fruit size and palatability being two obvious examples. Whether this occurred incidentally through the techniques used to cultivate the plants or intentionally through artificial selection, humans have created strains of domesticated…

Unknown Bacteria 228 Adisney Pino Professor Dowding Miami Dade College Section T/R 7:05PM Introduction Enterobacter aerogenes is rod-shaped bacteria that belongs in the family of Enterobacteriaceae. This rod-shaped bacterium is gram negative which makes it a facultative anaerobe which grew perfectly in 37-degree temperature. This species was motile and therefore it can synthesize an enzyme known as ornithine decarboxylase. This bacterium is prevalent in the intestines of animals…
