extinct. This illustrates that extinction is a very important evolutionary process which is only slightly less common than speciation. It opens up the planet for new lifeforms to emerge when dominating species fade away. Extinction is an on-going process and occurs on an uncorrelated manner at very low rates. ‘The fossil record shows that the background extinction rate for marine life is 0.1-1 extinctions per million species per year; for mammals it is 0.2-0.5 extinctions per million species per year’
Unconditioned Stimulus (UCS): The one which naturally triggers a response. For example if the sound of a slow music makes us sleepy, then this music is unconditioned stimulus. 2. Unconditioned Response (UCR): It is the unintentional reaction that occurs when the person is triggered by the unconditioned stimulus. In the above mentioned example, it is the feeling of sleepiness in response to the sound of the slow music. 3. Conditioned Stimulus (CS): It is the
have been pushed to extinction. “The passenger pigeon, the gastric brooding frog, the wooly mammoth, they all have one thing in common, they’re extinct… dead as a dodo, if you will. In fact, scientists estimate that 5 billion species have come and gone off this planet. But what if we could bring them back? What if extinction didn’t have to be a permanent thing? Right now scientists are using revolutionary new genetic techniques to try and bring back some of these species. For example, a wooly mammoth
schedule has a low but steady response rate and a very low resistance to extinction, meaning that it is the quickest way to bring about extinction. Fixed intervals give reinforcement every 30 seconds. The response rate speeds up for this schedule as the next reinforcement becomes available, meaning that there is a pause after each reinforcement. This results in the response rate being low; the resistance to extinction is low as extinction happens quite quickly. Variable reinforcement is, on average, given
plants are been driven to the borderline of extinct from the planet. (Andrea, 2007) One of the example is Orang-utans. Orang-utans are losing their habitats and food resources as their home was been chopped down for the establishment of oil palm plantation in Indonesia. (World Wildlife Fund (WWF), 2014) Deforestation has caused the loss of habitats for animals and plants which leads to species extinction and the issues are becoming serious in this stage. (Web of Creation, 2013) In the past 500 years
Let me tell you a story. There was once a tribe, a community if you will, who lived unity. The hunters would go out every day to find meat while the gatherers would search the surrounding wilderness for easier sustenance. At night they passed their bounty amongst each other and slept with ease- totally satisfied with this existence. But then one day the most skilled hunter stood in front of the tribe and said, “I provide the most food; why must I share it with he who lazes around all day?” He proceeded
hace a nucleus. Prokaryotes were the only living thing on Earth for a billion of years. One example of prokaryotic cells is bacteria.It help the immune system grow strongerand remember how to fight diseases. You can also use it to create vaccines that kill diseases and virus that try to invade your body. There are many kind of prokaryotic cells in the world. Beside bacteria, cyanobacteria is another example, it’s major group of prokaryotes. We wouldn’t be here if it wasn’t for cyanobacteria, it create
Nowadays, humans are destroying the environment unconsciously. This type of problem creates havoc in our world. For example; cutting trees and plants to increase the area of farming affect some species of animal and plant loss their habitat, using chemical fertilizers, herbicides and insecticides to increase agricultural production which make soil and water cause toxic and kill the animal. All of these aspects are going to be based on the ideas from “The New Atlantis” a short story by Ursula K.
Case Study: Oliver A functional behavior assessment is an investigative process that results in an understanding of why someone displays the behaviors they display (Steege, Watson, & Watson, 2009). Through the use of assessment tools provided, triggers, motivators, and reinforcers, of behavior can be identified which are specific to the individual. It is through identifying these unique characteristics we are able to develop intervention plans which are tailored to the individual. In order to
Karl Albrecht. He defines fear as, “An anxious feeling, caused by our anticipation of some imagined event or experience.”. This definition is very useful because Albrecht’s article focuses on the five basic fears which addresses all that we as humans biologically fear. He also says that if the fear that we feel does not boil down to be the fear or some form of the fear of extinction, mutilation, separation, loss of autonomy, or ego death then it is not really a warranted fear. He says this
