Lesson 3 Essay Questions: 1- Compare and contrast directional selection and disruptive selection, and provide an example of each. Directional selection occurs when one extreme of a trait is favored and the distribution curve shifts in that direction. An example of this is the human struggle with malaria. The mosquito Anopheles transmits the disease. A new drug for the disease and a insecticide for the mosquito was created. But over the years they became resistant to it and multiplied, shifting the distribution curve toward the resistant type of parasite. Disruptive selection is where any two extremes of a trait are favored over any intermediate phenotype. For example, British land snails are found in low vegetation areas. The thrushes …show more content…
So, if the plant entices an animal, say a bumblebee, to come to it by offering it some sweet nectar, then plant can attach some of its pollen to the back of animal and it will carry it to a new
The two different types of selection differ because instead of the subject only going in one direction it will split off and go two different ways. This would be disruptive selection where there is more than one option to select or two distinct groups. For example, if some flowers and their colors. The main colors may be red, pink and white primarily, say that the more dominate color being a pink flower. What happens if we remove the pink flower from the equation? It would cause the flowers to shift toward the dominant color which in this case you might think is the red. However, in this case it is not because between red and white is the least drastic and according to phenotypes would be the color that would be dominate if pink was eliminated as an option in a directional selection there is only one trait and it is always that dominant trait that dictates body of the population. Directional selection is more based of natural selection and survival. Examples would be things such as a giraffe having a long neck to reach high foliage than other animals for survival or a bunny being a color more specific to blending into its surroundings.
The Social Model of disability came about through the disability movement and other organisation campaigning for equal rights, opportunities and choices for disabled people. The social model of disability recognises that any problem of disability are created by society and its institution and that The Discrimination Acts are tools to help to improve the response of society to disability, also a wheel chair user is not hampered by their disability but by lack of adequate access to buildings. The social model may impact upon our practise as we would provide inclusive environments as a starting point for all children. The Scope website stated ‘The social model of disability says that disability is caused by the way
Traditionally, nutrition programs were targeted to the indigent and poor populations in developing countries. Many of today's Americans are malnourished also, but they are inundated with unhealthy foods and require a multidisciplinary approach to nutrition education. What would be the three most important points to include in a public nutrition program? Provide current literature to support your answer and include two nutritional education community resources.
1. The nation is at war, and your number in the recently reinstated military draft has just come up. The problem is that, after serious reflection, you have concluded that the war is unjust. What advice might Socrates give you? Would you agree? What might you decide to do? Read the Introduction, Chapter 2 Crito and the Conclusion Chapter 40 Phaedo by Plato.
Matt Lamkin’s “A Ban On Brain-Boosting Drugs is Not the Answer” first appeared in Chronicle of Higher Education in 2011. In this essay Lamkin aims to convince his reader not to deter improper conduct with threats, but to encourage students to engage in the practice of education. Lamkin tells us “If colleges believe that enhancing cognition with drugs deprives students of the true value of education, they must encourage students to adapt that value as their own” (642). Appeal to logic, consistency, and compare/contrast are techniques Lamkin skillfully uses to create a strong effective essay.
“Assess own leadership behaviours and potential in the context of a particular leadership model and own organisation’s working practices and culture using feedback from others”
All of us have formed habits in our daily life. Even though some of these habits only exist in our subconscious and we cannot actually make sure whether they are real or only the conjectures. But it is undoubted that all of our behaviors are influenced by our desires on specific objectives. In the book, the power of habit, Charles Duhigg explained the definition of a habit as an effort-saving instinct. “When a habit emerges, the brain stops fully participating in decision making” (20). To support his opinions on habits, he introduced the three-step model of a habit loop, the theory of golden rule of habit, and the role of a craving brain and belief in the process of a habit changing. Through learning

Natural selection is when organisms develop traits, so that they will be better adapted to their environment. Natural selection affects every living thing in the world. There are the examples of animals blending into their environment to hide from predators. Also there is when a thing living in a cold climate grows more hair to become warmer, and not die. Certain traits are more common in a population because the traits increase an individual's probability of surviving and reproducing.
Finally selection this is after the species has separated, natural selection effects populations separately. As each area is different the selection pressures are different, in which why their characteristics are different as they are ‘selected for’ their habitat. An example of selection includes warrior ants, in which they have chemicals that tell other ants in their family not to attack. Some of these ants have adapted and learnt to imitate the chemical signal from other colonies so they can invade another colony and the workers wouldn’t know (Your dictionary, 2015).
There are so many events that change one’s life that it is rather difficult to try and decipher which of those events are most important. Each event changes a different aspect of your life, molding how one’s personality turns out. One of these events occurred when I was about twelve years old and I attempted to steal from a Six Flags amusement park. My reasoning for stealing wasn’t that I didn’t have the money, or even that I wanted what I stole all that badly, it was that all of my friends had stolen something earlier that day and didn’t get caught. After getting caught I resolved, because the consequences are just not worth it, never to steal or give into peer pressure again.

In this story the author tells us about a girl named Sylvia, the narrator, who lives in a very low income family. A place where school is not a priority. A place where it is more important to be strong and hard, than to read a book. This was the thought anyway, before Miss. Moore moved in. She was a school teacher who took it upon herself to teach the neighborhood kids. On one summer afternoon in particular she was going to take the kids into town on a field trip. The kids are not at all happy about this because they know it is summer break and they are not supposed to be in school in the summer. They would rather be at the pool playin’, but Miss. Moore knows that if these kids want a chance at a better life,
