Exam 1 Review BIO 130: Introduction to Environmental Science Unit 1 Be able to define an environmental factor. There are two types (condition and resource). What is the difference between a condition and a resource? Be able to categorize particular environmental factors as conditions OR resources (for example‚ temperature is a condition and not a resource). Be able to rank from smallest to largest: ecosystem‚ landscape‚ biome‚ biosphere Be able to rank from smallest to largest (in terms

2a) was used but the final pH was low when elemental sulfur (Fig. 2b) was used. Acidithiobacillus ferrooxidans is an autotroph‚ which uses Fe+2 as an electron donor to obtain energy and in this process Fe+2 is oxidized to Fe+3. Hence‚ Fe+2 concentration plays an important role in its growth (15). In addition to Acidithiobacillus ferrooxidans‚ three other heterotrophic microorganisms

Viruses are tiny particles of DNA that have the potential to make people and animals extremely sick. It is ironic that viruses are very powerful‚ yet cannot reproduce by itself. They have various shapes‚ including rod-like‚ spherical‚ and phage. They generally have a similar structure: a protein coat called a capsid‚ a small amount of nucleic acid (DNA or RNA) that is located within the capsid. Important characteristics include: not living and no respiration. They can only reproduce within a host

What is Biodiversity? Biological diversity‚ or the shorter "biodiversity‚" (bio-di-ver-si-ty) simply means the diversity‚ or variety‚ of plants and animals and other living things in a particular area or region. For instance‚ the species that inhabit Los Angeles are different from those in San Francisco‚ and desert plants and animals have different characteristics and needs than those in the mountains‚ even though some of the same species can be found in all of those areas. Biodiversity also means

Section One : In the discipline known as taxonomy‚ scientists classify organisms and assign each organism a universally accepted name. The first part of the scientific name—in this case‚Ursus—is the genus to which the organism belongs. Agenus(JEE-nus; plural: genera‚ JEN-ur-uh) is a group of closely related species. Linnaeus’s hierarchical system of classification includes seven levels. They are—from smallest to largest—species‚ genus‚ family‚ order‚ class‚ phylum‚ and kingdom

Bio 1 River Ecology Lab Report Ecology is the study of relationships between organisms and their environment which includes both physical and biological factors. Humans have a major influence on ecosystems and this is very important in the waterways of California. The American River has been influenced greatly by humans by mining for gold‚ pollution through humans themselves‚ and an immense amount of other things (Becker 1992). We tested the growth of bacteria in the water of the American

(2): Plant Pigment Paper Chromatography All organisms need energy for their metabolic processes. They also need “food” to produce that energy. Plants are autotrophs (self-feeders). Plants produce their food through a process called Photosynthesis. The food that they produce is the sugar glucose. Animals and other organisms are heterotrophs (other- feeders). They must consume other organisms (plants) in order to eventually get their glucose. Both plants and animals use glucose as an input to the
