What is objective writing and how does one write objectively?
Objective writing is writing that you can verify through evidence and facts. If you are writing objectively, you must remain as neutral as possible through the use of facts, statistics, and research. This type of writing is best used when you as a writer need to present unbiased information to an audience and then let them determine their own opinion. News reports and school textbooks often use objective writing. To write objectively, the writer must keep the following in mind: - Be specific instead of vague or general. Rather than writing: 'almost everyone voted for him,' write: '82% of the company voted for him.' - Do not use opinionated, prejudiced, or exclusive language. Rather than writing: 'men and girls,' write: 'men and women.' Keep both equal, and keep both genders listening to you. - Avoid using first person to keep it more professional and less about you. Rather than writing: 'I believe…' try using a fact or credible source to prove your point like: 'According to Smith (1999).' - Try not to over exaggerate your writing. It can help to never use words such as 'really,' 'always,' 'never,' or 'very.' These words can make your writing appear falsified or weak. Rather than writing: 'the race was really close,' be more informational by writing: 'the race was close enough to demand two recounts.'
What are the applications of each of the following in biology? Include three examples of each with a brief description. 1. DNA in forensic science 2. Population evolution and microbial life 3. Biological diversity evolution 4. Population growth 5. Biomes and ecosystems
1. DNA in forensic science: DNA in forensic science is used to: - Identify criminals based on the DNA, whether the criminal touched any object or any skin cells left behind. - DNA fingerprinting is a process for determining a person's genetic makeup. - Perform a DNA test of the relatives to find out the criminal or the not guilty person. 2. Population evolution and microbial life: - Microbial life has been seemed to increase human immunity to a particular disease. - Microbes are currently being used in clinical trials to help improve the pace at which T-cells respond to the invasion of cancer cells. - Some bacteria can assist clean up oil spills by ingesting and breaking down sections of the oil, while others can help us figure out how climate change is affecting water quality. 3. Biological diversity evolution: - Biodiversity is quite resourceful to humans today for food, building, and medicine, spiritual and cultural enrichment. - The number of individuals with adaptable features increases over many generations, adjusting the entire population to a given ecosystem. As a result, natural selection uses natural genetic variation within a population to select for features best suited to the habitat environmental conditions. - Many species have evolved camouflage patterns and colors due to natural selection, making themselves less obvious to predators or their food. 4. Plant and animal evolution: One of the significant plant evolution applications is the weed, pest, and pathogen resistance evolution and the creation of breeding programs that maximize crop output or quality. The hypothesis of animal evolution states that present animals are modified descendants of previously existing animals and that these earlier forms descended from even earlier and diverse species. 5. Population growth: - An increasing population can fuel the Economic growth of the country. - As the population grows, so will the number of parents who invest in their children. - The economy is fueled by increased purchases of food, clothing, education-related expenses, athletic items, and toys. 6. Biomes and ecosystems: - Specific biomes support a specific ecosystem or a group of species to live. Water is the foundation of life, sustains life, and is home to innumerable animals that spend all or part of their lives in it. - Deforestation, unintentionally introducing invasive species, shooting animals, polluting rivers, spraying pesticides, allowing cattle to graze in woods, and other human activities changed due to the forest biomes. - Ecosystems provide all food, store all energy, fiber, genetic resources, medicines, fresh water, and minerals.
Find y if 73 - 17 = 46 + y.
When we want to solve for the value of a variable, we sometimes have to simplify an equation before we can isolate the variable. This happens when we can perform some type of arithmetic to one side of the equation because it has like terms that are not simplified. If 73 - 17 = 46 + y, the value of y is 10. Before we can begin manipulating the equation to isolate the variable, we have to simplify the equation. This is because there are like terms on the same side of the equation. By performing the math that we can, we convert this equation to the following equation. 56 = 46 + y Next, we have to subtract 46 from both sides of the equation to isolate the variable. 56 − (46) = 46 − (46) + y 10 = y
