What are the advantages and disadvantages of asexual and sexual Essay

What are the advantages and disadvantages of asexual and sexual reproduction in animals - Essay Example Division of the zygote takes place repeatedly resulting to the growth of an embryo. This embryo grows inside the female or outside in other animals into multi cellular organism. As a result of the shared genetic information in sexual reproduction by the gametes, the off spring produced contains variety. This constitutes part of the advantages of sexual reproduction since the genetic variation gives the species an advantageous element of survival. Furthermore, genetic variation results to evolution of species which form better organisms (Kent, 2000). This species have better surviving traits in the unstable environments. Species which reproduce sexually have low extinction rates. This is beneficial as it ensures continuity of population. Sexual reproduction has several disadvantages. To this end, the need to have both male and female mate for reproduction is some time inconveniencing since both may not be willing (Rinkevich & Matranga, 2009). It also consumes excessive time and energy to look for a suitable partner. Moreover, there is no assurance after fertilization that the nucleus cell of male will fuse with the female cell. .Furthermore, counter-productive genetic combination conditions should be stable. Asexual reproduction involves one organism producing an offspring identical to it genetically. It requires one parent to reproduce. In single celled organisms the parent cells are split into two cells’ with equal content by binary fission. Multi-cellular organisms use a process known as mitosis to split cells into cells with equal number of chromosomes. Asexual reproduction has several advantages. One, it is very beneficial to the types of animals that stay in one area or not able to look for mates to reproduce. The fact that asexual reproduction does not need mating of female and male gives is advantageous to these animals as they are able to reproduce as they are. Another advantage, since no need to find a mate many off springs are produces

Dramatic Tension in An Inspector Calls by J.B. Priestly Essay -- Engli

How does J.B. Priestly create dramatic tension in An Inspector Calls? In "An Inspector Calls," dramatic, tension is created in many ways. First of all is Conflict. There is conflict within the family initially. This is mainly in the generations; Mr Birling isn't particularly proud of his son Eric and so he isn't as kind to him as he is to other members of the family. Just keep quiet Eric. As you can see, he doesn't really respect him at all. This is what Mr. Birling says to Eric after Eric asks if it was because of Mr. Birling firing Eva that she committed suicide. Rubbish! If you don't come down sharply on some of these people, they'd soon be asking for the earth. This is Mr. Birling's response after Eric tells him that he wouldn't have fired Eva. Eric is implying here that Mr. Birling was over-reacting in throwing her out, and that he should have kept her working there. After this, Eric once again brings the topic up that Mr. Birling shouldn't have fired Eva. Eric says this: And I don't see why she should have been sacked just because she'd a bit more spirit than the others. This is how Mr. Birling replies to that comment: (Rather angrily) Unless you brighten your ideas, you'll never be in a position to let anyone stay or to tell anybody to go. It's about time you learnt to face a few responsibilities. Mr. Birling saying this shows that he has no faith in his son and he feels that he will not amount to anything. Mr. Birling prefers Gerald to his son. This is obvious as he is always flattering him and giving him more respect than to Eric. This is probably another way to make Eric feel bad, to maybe get him motivated. This is the sort of thing Mr. Birling says to Eric: I'm treating ... ... to help with the baby. All of the sequences connect well and very neatly which helps to give the play more tension; because of what one person, the next thing can happen, and because of what they did, the next thing can happen and so on. This makes the play more exciting and helps it flow better, which shows it is professional and well written. In conclusion to the question, J. B. Priestly creates tension through Conflict, Dramatic Irony, Interrogation Techniques, Relief, Creation of Doubt, chain of consequences and Mystery, and Shock.

The play can get exciting in certain places due to the tension of what will happen next; what effect will one thing have on another? All in all, the play is Very well written and the dramatic tension is excellent.

Nutrition Essay

1.Select a sweetener. Sucrose 2.Explore the history of the sweetener (when it was developed, its composition). Sucrose, according to our text, is composed of one glucose (the most common sugar molecule) molecule and one fructose (the sweetest natural sugar) molecule. The bond is called glycosidic linkage. Because of this mixture, Sucrose is known to be sweeter than lactose or maltose (the other 2 out of the 3 most common disaccharides, which is a carbohydrate compound consisting of 2 or more molecules joined together). The history of sucrose dates back to thousands and thousands of years ago when the sugar cane was discovered in the South Pacific, rumored specifically to have been found in New Guinea. Its molecular formula is C12H22O11. (taken from Wikipedia) 3.Discuss safety and the sweetener that you have selected. When pure, sucrose has an energy content of 3.94 kilocalories per gram, which helps give someone that instant â€Å"jolt of energy† they are looking for. This becomes unsafe when consumed in large amounts and when looking at it from a health standpoint, should not be used for that jolt. When using Sucrose in moderation, or small doses, it does not pose as may risk factors as it does when over consumed. Also, please note that there really is not any nutritional value in Sucrose itself. Typically, sucrose is spoken of as table sugar. The most common health risk of Sucrose would be linked to tooth decay and other dental issues. Other health issues linked to a diet with an over-abundance of sucrose would be hypoglycemia or diabetes mellitus. 4.Examine the relationship between the sweetener that you have selected and obesity. There is a lot to be said about sugars of any type in your diet. When it comes to Sucrose consumption leading to obesity, it really depends on the type and frequency of the consumption itself. For instance, some drinks containing high levels of sucrose may be linked to the development of obesity and insulin resistance. Also, as said above, it can lead to dental problems and possibly diabetes. It has also been assumed that Sucrose can lead to metabolic syndrome. This is a combination of medical disorders that can increase diabetes and cardiovascular diseases when working together. Because this occurs within the insulin-resistant, it does not necessarily mean you are obese if you’re diagnosed, but it does mean that it can increase ones chances of being obese. So when all is said in done, use Sucrose or any sweeteners for that fact, in low-moderation to avoid any health risks that result in the o ver consumption of Sucrose.

Essay on The Economy of Afghanistan - 1370 Words

The economy of Afghanistan has significantly enhanced since the decline of the Taliban in 2001 due to the infusion of international assistance, the recovery of the agricultural sector, and service sector growth. Regardless of the progress of the past few years, this country is extremely poverty stricken, highly dependent on foreign aid, and landlocked. A lot of the population continues to suffer from shortages of jobs, clean water, electricity, medical care, and housing.

Living Like Weasels, Shooting An Elephant, And Virginia Woolf

The human is the most complex living being on the face of this earth, yet human roots are sometimes forgotten. Through Charles Darwin’s theory of evolution, it is clear that animals are the brothers and sisters of the human race. In turn, human habits resemble those of all the living beings which creates unity between all walks of life, determining the same fate for all. A similar concept relates the three works: Living Like Weasels, Shooting an Elephant, and The Death of a Moth by Annie Dillard, George Orwell, and Virginia Woolf respectively. The authors explore the nature of such creatures in order to achieve a better understanding of their motives, all the while gaining insight on the cycle of life. Both Living Like Weasels by†¦show more content†¦Woolf paints a similar picture as the moth’s â€Å"legs agitated themselves once more...the enemy against which he struggled†¦was [somehow] opposed to the...moth...It was useless to do anything†¦One coul d only watch the extraordinary efforts made by those tiny legs against an oncoming doom,† being death (Woolf 195). This story parallels that of Orwell’s and explores the moments before the unavoidable force of death sweeps one away. The essays show that it is â€Å"useless† for anyone to do anything in this â€Å"powerless† state because the time has come. All one is left to do is to endure the pain as the senses are slowly removed and as he/she transitions onwards, displaying that change is also a part of the cycle of life, and one must develop patience and endurance to handle change. Moreover, Dillard’s and Woolf’s pieces investigates the process of death, the end of the cycle. Dillard believes that by â€Å"grasp[ing] your one necessity and not let[ting] it go, to dangle from it limp wherever it takes you. Then even death†¦cannot you part† (Dillard 66). In other words, one should seize their destiny till their body decomposes i n the ground,

Similarities And Differences Between Martin Luther King Jr...

Even after almost fifty-years, Martin Luther King Jr. and Malcolm X endure as cherished, powerful, and instrumental leaders in the Civil Rights Movement. Although they were advocating for the same cause, they were not always on the same page about the means. They were both ministers, although of different faiths, and had different thought processes. In his autobiography, Malcolm discusses his childhood in poverty and the ramifications that this caused such as dropping out of school in the eight-grade. Upon moving to Boston from Nebraska, Malcolm was in yet another disadvantaged environment that was interwoven with violence, eventually leading to his incarceration that lasted six years. Martin, however, was a well-educated man from a†¦show more content†¦When it came to violence, Martin opposed, feeling that there was a thin line between aggression and defense. He felt that violence would lead to death and a spiral, making things worse rather than fixing them. In Martinâ€⠄¢s ‘Where Do We Go From Here† speech from August 1967, he states â€Å"Through violence, you may murder a liar, but you can’t establish truth†¦ murder a hater, but you can’t murder hate... Darkness cannot put out darkness; only light can do that.† Malcolm on the other hand, spoke of self-preservation and self-defense. He saw the whites as the ones guilty of violence throughout history, and now it was the time for African-Americans to stand up for themselves. Martin felt that black Americans should be paid for the long history of oppression and should have equal rights. Although both men had experiences that shaped their different philosophies, once involved in Civil Rights they had similar experiences. Both men had seen and felt prejudice, been to jail, got death threats, homes attacked. The difference was how to respond to these instances. Martin wanted to get the prejudice and brutality in the spotlight, using non-violent means to cause an em otional reaction to spark change. Malcolm wanted African-Americans to take things into their own hands, with violence being a tool. Both men got their messages across through speeches, which were also different.
