Biology - Essay Example Rigging up the filter in this fashion keeps it from bumping into any trees or other objects outdoors, which would taint the entire experiment. Next, I smear Vaseline on both sides of the filter. The entire filter is practically covered with the Vaseline, which will enable any solid matter in the air to stick to the filter, allowing us to see what is exactly in the air that we breathe every day, as well as have a means for getting a rough measurement. While we will not be able to measure the particles in a numeric sense, we will have a clue as to what is going into our lungs when inhaling in the air outdoors. As it stands right now, the Vaseline covered coffee filter is a very shiny white. It has a very shiny clean appearance, and it feels very slick to the touch. There are no dust particles and other solid matter on it. However, by the end of the experiment, I hypothesize that the entire filter will be covered with dust and other solid matter, being that there are a great deal many p ollutants in the air from the things that we do in our everyday environment. The coffee filter will be covered so much that the solid matter will be caked onto it, and the shininess that is now present will be no more. The filter will have a completely dirty appearance, as well as being gritty to the touch. The filter appears to have very small and gritty looking dirt particles on it, which I can assume are a mixture of dirt and other solid matter in the air that are caused by pollution. The dirt particles and solid matter are trapped by being stuck to the Vaseline. The filter still has a lot of shininess and cleanness left on it; nevertheless, it is beginning to look dirty. The dirt particles are of a brown color, and they appear to be small, such as like that of grains of sand. Dust particles are also mixed in along with the dirt particles, and the dust has a powdery look. The layer of dirt, solid matter

Animal adaption report Essay Example | Topics and Well Written Essays - 500 words

Animal adaption report - Essay Example For instance, a sunflower’s ecological niche is absorption of water, lights, and nutrients. Offering food to some organisms and releasing oxygen in the atmosphere (Daily, 2014). A structural adaptation is defined as the physical characteristics that an organism develops in order to survive in a particular environment. The video shows a type of reptile that has developed sharp teeth to grasp slippery seaweed. The developed teeth is an example of adaptation that gives the reptile better likelihood of obtaining food thus surviving in the particular habitat. They have also developed a flat snout that helps them graze. Physiological adaptations accounts for the way an organism adjusts or regulates bodily functions in response to a situation or its environment. An example from the video is the oxygen carrying capacity that the iguana reptile has developed to enable it dive for up an hour to get seaweed. The ability to dive deep enables the iguana reptile to dive deeper thus finding food. An example of behavioral adaptation from the video is the migration of birds (albatross). Albatross migrate in response to their mating instincts. The behavioral adaptation that albatross has developed for mating allows their population to gather in one place and at a specific time and ensures their ongoing reproduction. In the former times, cheetahs were prevalent and common in various regions of the pre medieval world. However, nowadays, they are sported in specific parts of the world mainly in sub-Saharan Africa, emote and secluded North African regions, as well as Iranian and Pakistani enclaves. The largest Cheetah population’s concentration is in Namibia, Southwest Africa. This place is therefore famous as "the land of cheetahs." The cheetah’s diet includes mammals ranging from small to medium size, which are lighter than 40kg. Some of these are impala, gazelles, and wildebeest calves. Other prey
