Offspring

Eagles and their offspring, in particular, faced many difficulties in keeping their population alive when DDT use was at its height. “…DDT and its relatives alter the bird's calcium metabolism in a way that results in thin eggshells” (Stanford). The thinning of eggshells meant…

Exploring Mythology Myths have been around for many years, and generations. In fact myths have been around since man learned to speak. Some famous myths are still well known around the world like Santa Claus, or Zeus the Greek god of the sky. There are different kinds of myths some can be about heroes, gods, or kings, and honesty a myth can be about anything, or anyone it just has to get popular, so people would retell it for generations. One very well known myth, is the story of the Greek god…

Dan Marquis proposes that it is wrong to kill a fetus for the same reason that it is wrong to kill a person: killing them would deprive them of their future of value. I want to argue, however, that this reasoning cannot be used to conclude that all abortions are impermissible. In particular, I argue that Marquis does not give us good reason to think that abortions that occur within the first 25 weeks of pregnancy are impermissible. The paper will include two main arguments. Firstly, I will argue…

humans (Hayes et al, 2010). According to Hayes et al’s research (2010), 10% of male African clawed frogs that were induced with 2.5 ppb of Atrazine became females. These feminized African clawed frogs were able to become pregnant, but all of their offsprings were male because the original…

The Pan American Health Organization have put out a few recommendations to combat the Zika outbreak. The organization suggests reducing and eliminating any mosquito breeding site on your property. Related to this, people should close off their homes to mosquitos. Such methods include using window screens rather than an open window with no screen. Also, the PAHO recommends sleeping under a mosquito net to prevent bites while you are asleep. Visitors to areas with a Zika outbreak should wear…

According to Dictionary.com, a tool is defined as, “anything used as a means of accomplishing a task or purpose.” In the novel Ender’s Game, by Orson Scott Card, Ender the protagonist is told that “Human beings are free except when humanity needs them… Individual human beings are all tools that the others use to help us all survive” by a man named General Graff. Although all human beings deserve freedom, I believe that the statement, “Human beings are free except when humanity needs them……

chromosomes, while the turtles on another island have 48 chromosomes. How would you explain this observation? How do you think the turtles with 48 chromosomes came into being? If you mated the two types of turtles together, would you expect their offspring to be phenotypically normal? Would you expect them to be fertile? Explain. Judging by the information provided it would seem as if the turtles would be linked together as they would both be in the polyploid haploid set family that would be…

evolve defenses from malaria - any genetic factor that confer resistance against it would give descendents a chance to have offspring, while those without protection were more likely to not reproduce.” (http://www.livescience.com) If we didn’t evolve to where we were less likely to get malaria it would be harder for us to reproduce. Then there wouldn’t be anymore offspring. “There are lots of examples of defenses against malaria. Sickle cell anemia is the best known - the disorder deforms red…

child. Not like Huxley’s Brave New World where there is no bearing of offspring and a one-world government is in power. Artificial wombs are giving childless couples more options, ending childbirth problems, women with damaged uteruses and wombs can have babies. There will be no premature babies. These mechanical wombs will provide a drug and alcohol-free environment. It will give homosexual couples the option to have their offspring. The novel Brave New World is about conditioning and…

evolutionary hypothesises to avoid incest. (Aoki, 2005) It is also interesting to contrast the literature review of Aoki to Leavitt’s literature review since the latter suggests selection pressures that tolerate incest (i.e. it is able to increase offspring and mating chances during circumstances of resource scarcity). Even though Aoki’s work is specifically on our species (cross-cultural studies) and Leavitt’s is based mostly on non-human species, both articles provide critiques on the…
