My Mysterious Mentor free essay sample

â€Å"Elementary, my dear Cline.† I have imagined hearing those words spoken to me on countless occasions. Solving impossible mysteries has always been my dream job, and there isn’t a man more skilled in that field than the fictional Sherlock Holmes. His skills of deduction and observation were unmatched, and I needed to learn how he did it. Spending a year with this masterful investigator would teach me the intricacies of his genius mind—and how to emulate it. When I was younger much of my time was spent outside, magnifying glass in hand, observing every individual blade of grass. I wanted to see if I could figure out where my dog had treaded earlier that day by looking for bent grass. I never once figured it out, but I knew, even at that age that observation was the key to everything I wanted to be. Did you notice that footprint over there, Miss Cline? I could hear Mr. We will write a custom essay sample on My Mysterious Mentor or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Holmes asking me. Truthfully, I hadn’t, but I would next time. When I grew older, around thirteen years old, my focus shifted from wanting to solve mysteries that concerned stolen objects, and other small-time crimes, to solving murders. I had discovered forensic science. My seventh grade science teacher, Mr. DePew was the first person to ever introduce this realm of science to me. One day we walked into the classroom and were assaulted by the bitter odor of onions. There was a group gathered in the far corner of the room, and on the floor was the taped outline of a body. A murder had occurred! Forensics was so fascinating. It was just like the fictional detective work that I had read or watched, but it felt more real. Detectives in fiction found the clues easily and always found the culprit, but that wasn’t how it worked in our class. We were given all the clues, and we had to figure out how they fit together, and what role they played in the murder. There wasn’t a single group in the class that solved the murder correctly. Yet after doing that simulated case, I was hooked. I knew I wanted to be a forensic scientist. After our murder case in Mr. DePew’s class, I went on a forensics spree. My favorite toy was a giant plastic green case that held all of the essential crime scene items. Fake blood that I could mix with chemicals to simulate real blood, a microscope, and my very favorite finger print powder. The small vial of black powder was spread all over my house, as I attempted to lift fingerprints from every surface possible. I would dust the windows and tables and find a fingerprint, and then I would lift it with a piece of tape and place it in a notebook. These rituals fueled my desires, and allowed me to feel like a member on CSI, finding the key piece of evidence to solve a dastardly crime. I always knew that in order to achieve my dream career, college would be necessary. However, forensic science isn’t usually offered as a course in most universities, as there are so many components that go along with it. There are specifics, including forensic pathology, which is concerned with autopsies, and forensic entomology, which has to do with bugs, but my interest is in the crime scene. After much searching I found out about Eastern Washington University. Unlike most colleges, EWU lists forensic science as one of their main courses. I knew then that Eastern was the university I wanted to attend. Be observant, for the little details are by far the most important, Miss Cline. Never forget that. The parting words of Mr. Holmes are ones that I will follow for the rest of my life. They ring true for my goals, and I will forever hone my skills of observation. At the end of the year, Mr. Holmes shook my hand and said, Case closed, Miss Cline. Case closed, indeed, Mr. Holmes.

Praying Mantis Sex and Cannibalism

Praying Mantis Sex and Cannibalism The female praying mantis is often painted as an evil seductress, a cannibalistic lover that lures males closer, only to eat them after mating. Is her reputation deserved? Does praying mantis sex always end in cannibalism of the male? Female Mantis Shaming or Truth? Rumors of the praying mantis cannibalistic tendencies began when scientists observed their mating behavior in a laboratory environment. Entomologists would offer a captive female a potential mate and would quite often be horrified to watch the female bite the head or legs off the smaller male- sometimes even before mating. After the male had served his copulatory purpose, he was nothing more than a good meal for the female and her upcoming offspring. For a long time, these observations of praying mantis sex in the lab were thought to be the way things were in the mantid world.   Much Less Common in the Wild After scientists started observing praying mantis sex in a natural setting, the story had a different ending, which is good for the males. When unconfined by laboratory terrariums (and not starving), the majority of praying mantis mating ends with the male flying off unharmed. By most estimates, sexual cannibalism by praying mantis females occurs less than 30 percent of the time outside the lab. Those are better odds for the fellows than what had been seen in the lab. Praying mantis sex, it turns out, is really a rather romantic series of courtship rituals and dances that typically ends satisfactorily and safely for both parties involved. How Males Choose Females Given a choice between females, male praying mantises will move toward females seen as less aggressive (i.e., ones they hadnt just seen eating another male) more often than the more aggressive females. The males also tend to prefer to mate with females that appear fatter and more well fed than others, as the skinnier and hungrier mantises are more likely to eat their mates during or after sex. This could also point to the males being more attracted to females that are healthier, for the betterment of their offspring.   Advantages of Beheading Your Mate There is a decided advantage for the female if she does decide to behead her lover. The praying mantis brain, located in his head, controls inhibition, while a ganglion in the abdomen controls the motions of copulation. Absent his head, a male praying mantis will lose all his inhibitions and consummate his relationship with wild abandon. And what if shes hungry? For certain, a slow-moving and deliberate predator like the praying mantis is not going to pass up an easy meal. If a male makes the unfortunate choice of a hungry female for a mate, hes probably going to be toast after theyve mated. Either Way Could Benefit the Males A twist: Being eaten by the female paradoxically may mean that that particular male has more of his genetics making it to the next  generation  if more of his sperm fertilize his mates eggs while she is eating parts of him. More eggs are laid by females who eat their mates as well (88 vs. 37.5 in one study). However, if a male can mate more than once, that also increases his odds of having his genetics passed on.
