The text, 2BO2B by Kurt Vonnegut talks about a man named Edward K Wehling Jr, who waited for the birth of three triplets. Because of population control, Mr.Wehling was only able to take one of the three triplets home, according to the law. He sit in the waiting room, followed by Leora Duncan and Dr. Hitz. Mr. Wheeling becomes angered by the law, then shoot the two and himself to make room for the triplets to all survive. In the text, having population control benefited life, but not others. The…

Yes, I believe that using controlled fires to protect wild areas are beneficial. Controlled fires help maintain the health of an existing natural area containing native plants and they help manage weeds and other growth, which helps to reduce the risk of wildfires. Fire is one of the best outdoor management tools for invasive plant control. For over 10 years ecologists have been using this technique, which has spread to many other trained people to use as a tool. Woodlands, prairies, and…

mitochondria and requires oxygen, anaerobic metabolism occurs in the cytoplasm and it does not require oxygen. During aerobic metabolism the hydrogen and carbon molecules from dietary fats, proteins, and carbohydrates are mixed with oxygen to form carbon dioxide and water as energy is released. These end products that are produced during aerobic metabolism are to some extent harmless and simply eliminated from the body. The citric acid cycle, sometimes called the Krebs cycle, provides the final…

Your home is more likely to be hurt by termites than a fire. Every year, termites cost the American economy $5 billion. Whether you live in the woods or on the beach, your property is at risk for termite damage. By detecting the signs of an infestation early, you can limit the repair cost and damage caused by termites. Look for Insects If you have termites in your home, one of the first signs is a rise in flying insects. Known as swarmers, these winged creatures will fly around your home and…

Paul Bogard, writer of the article, “Let There Be Dark,” presents interesting and engaging information to gain support for the reduction of artificial light pollution in our night skies. He displays the importance of changing from the current state by giving us some reasons why we can’t let the light pollution progress, examples of how we can fix it, and engages our feelings of responsibility when we see that we need to take care of our world. The first point he makes is a common daily…

chloroplasts important for plants? Chloroplasts are important for plants because they contain Chlorophyll, used in photosynthesis. The Chlorophyll is what made it possible for plants to absorb and process the sun's energy and combine it with carbon dioxide and water to grow and make food. Photosynthesis also releases oxygen for humans to breath. 2) List two reasons and explain why the chloroplasts were helpful for the sea slug. One reason for why the chloroplasts are helpful for the sea slugs…

Lake Poopó, Bolivia’s second largest lake disappeared due to the constant drought in Bolivia and global warming. It is now littered with dead fish and abandoned boats. Three years ago, Lake Poopó took up 4000 square miles of space, twice the size of Lake Tahoe. Now, none of that immense lake remains. The saline lake has also shrunk because of warmer temperatures, fall os precipitation levels from El Niño, and because too much water was taken out of the river that fed into Lake Poopó, local…

When Mount Vesuvius had erupted in 79 AD the eruption caused fatal damage to the environment, causing many animals to be killed by the toxic gases released from the volcano or the chemical in the water caused by volcanic ash in the animal’s water source. Mount Vesuvius had a major effect on vegetation because it left an entire region as a desert wasteland, any plant that had an encounter with lava had died straight away, through other plants died from volcanic ash that was ejected from the…

Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…

18B. Describe two different processes (connected to different mechanisms) that cause down- and upwelling. Upwelling and Downwelling refers to the upwards and downwards movment of water molecules in the ocean system. Downwelling happens when near-surface water sinks and upwelling is the subsurface waters rising. Downwelling occurs when the water at the surface of the ocean becomes denser than the water below it, this dense water then sinks. Water becomes dense when it becomes saltier or colder…
