Name and describe three types of environmental pollution.
Three types of pollution are noise pollution, water pollution, and light pollution. Noise pollution can be defined as an excess of foreign noise in an ecosystem. Common sources include boats and ships within water bodies and anthropogenic activities in terrestrial environments. Within water bodies and on land noise pollution may inhabit organismal communication, hunting behavior, or mating behavior. Noise pollution may also have detrimental physical and mental effects on humans. Water pollution occurs when water sources are contaminated. Often this happens when industrial wastes are dumped into water bodies. Water pollution can also occur due to nutrient runoff from surrounding agricultural lands or oil spills. Water pollution can affect all living organisms. These pollutants work either by driving the process of eutrophication or directly poisoning organisms with their toxicity. Humans introduce light pollution into environments by altering natural and artificial light levels. Coastal tourist destinations as well as construction sites and residential areas are leading sites of light pollution. This type of pollution can negatively influence organismal mating, natural predator-prey relationships, and plant growth.
Within a piece of literature themes, symbols, and motifs can be identified and described. Define each of these ideas. For each, provide a common example.
A theme within a piece of literature is the main idea, or the message, behind the work that the author is conveying to the reader. Often, there is more than just one theme within a piece of literature. Themes may be stated directly or indirectly throughout a work. Common themes within literature include love, censorship, and maturity, or coming of age. Symbols are used in literature to provide meaningful connections between a specific item, character, or action and an abstract idea or value. A symbol is a representation and means more than its literal definition. A common example is a dove as a symbol of peace. Motifs are often symbolic and contribute to the development of a theme. Alike symbols, a motif can be an item, concept, or idea. However, motifs are constantly repeated throughout a work, while symbols are used less frequently. Weather and death are motifs commonly identified within literature.
Photosynthesis is a process that occurs within plants and some organisms that allows for the production of energy as well as byproducts. Briefly discuss the necessary components that must be present for photosynthesis to occur as well as the common byproducts of the process. Using this information, write a balanced chemical equation for photosynthesis.
In order for photosynthesis to occur, carbon dioxide from the atmosphere, water, and sunlight must be present. These components undergo a series of reactions within plants and some organisms known as photosynthesis and produce glucose, which the plant or organism uses as a food source, and oxygen, which is released into the atmosphere. Chemical equation: 6CO2 + 6H2O --> C6H12O6 + 6O2
