The question is who are we? And where do we come from? Rather then spark a religious verse science debate and draw a very emotional line in society we let everyone believe what they want to believe. However regardless of what you want to believe facts are facts and science is science. After

If evolution is descent with modification applied to life on Earth‚ then microevolution can be called the small‚ measurable evolutionary changes within a population while macroevolution is large evolutionary change over long periods of time - short term and long term/big picture evolution‚ essentially. Microevolution works on a single population’s genetics and could be said to be the status quo of evolution that occurs consistently and universally while macroevolution occurs over many years or as

virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms‚ from animals and plants to bacteria and archaea. All viruses have genes made from either DNA or RNA‚ long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell What is a fungus

AP Biology Essay Questions UNIT 1 1. The unique properties (characteristics) of water make life possible on Earth. Select three properties of water and: a. for each property‚ identify and define the property and explain it in terms of the physical/chemical nature of water. b. for each property‚ describe one example of how the property affects the functioning of living organisms. UNIT 2 Describe the chemical composition and configuration of enzymes and discuss the factors that

Origin is on bacteria line in the middle. Archaea are generally shorter lines‚ bacteria are the intermediate lines and eukaryotes are the longest lines. Organisms: Are there going to be specific organisms from throughout the class on this exam or just from lecture 2? 3. What are the methods

Ecosystems Components SCI/256 A region that receives fewer than 10 inches of rain annually is considered a desert. This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes

evolution The phenomenon that populations of organisms change over the course of many generations. As a result‚ some organisms become more successful at survival and reproduction natural selection The process that eliminates those individuals that are less likely to survive and reproduce in a particular environment‚ while allowing other individuals with traits that confer greater reproductive success to increase in numbers. Directional selection is when natural selection favors a specific
