Exam: Chapter 1 Study Guide 1. What are the 11 levels of organization? Briefly define each. Atom - fundamental units of matter‚ building block of all substances Molecule - atoms joined in chemical bonds (an association of 2 or more atoms) Cell - smallest unit of life Tissue - organized array of cells and substances that interact in a collective task Organ - structural unit of interacting tissues Organ System - a set of interacting organs Multicelled Organism - individual that consists

Fermentation Lab Introduction For bacteria and many single-celled protists fermentation is a common anaerobic pathway that the cells use to collect energy from carbohydrates to form ATP. The process for fermentation begins in the cytoplasm with a process called glycolysis‚ which converts one molecule of glucose into two molecules of pyruvate. When glycolysis is complete four ATP would be produced but the net yield would be two ATP taking into account the initial investment of two ATP

Malaria is a mosquito-borne infectious disease of humans and other animals caused by protists (a type of microorganism) of the genus Plasmodium. It begins with a bite from an infected female Anopheles mosquito‚ which introduces the protists through saliva into the circulatory system. In the blood‚ the protists travel to the liver to mature and reproduce. Malaria causes symptoms that typically include fever and headache‚ which in severe cases can progress to coma or death. The disease is widespread

Session 1 We use the scientific method every day. Imagine your car doesn’t start one morning before school. Which of these is a reasonable hypothesis regarding the problem? I’m out of gas. A scientific theory explains what we know to this date about a natural event. Which of the following is a theory? There is molecular and biochemical evidence that all organisms are related. Choose the answer that best describes the sequence of the scientific method. observation‚ hypothesis‚ experiment‚ conclusion

primitive‚ simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes‚ which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and protist organisms‚ prokaryotic cells are believed to have been amongst the first on the Earth and very well may out-survive all other organisms. Examples of prokaryotes are bacteria and archaea and eukaryotes include fungi‚ animal and plant cells. One of

evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of eukaryotes. These eukaryotes then evolved into protists‚ fungi‚ plants‚ and animals. As they evolved‚ so did the way they reproduce. From simple asexual reproduction (binary fission) to sexual reproduction thereby expanding the diversity of the life

Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

Certain bacteria‚ protists and archaea are also autotrophs. Autotrophs are able to create their own food using light source and photosynthesis process or through obtaining energy through oxidation. Some example of living organisms that is autotrophs that is not plants are

Cnidaria is a large phylum composed of some of the most beautiful of all the salt and freshwater organisms: the true jellyfish‚ box jellyfish‚ coral and sea anemones‚ and hydra. Although Cnidaria is an incredibly diverse group of animals‚ there are several traits that link them together. Most cnidarians are dipoblastic‚ which means that they are composed of only two layers of cells. The outer layer is known as the ectoderm or epidermis‚ and the inner layer is known as the endoderm or gastrodermis
