Exercise 3A is a study of mitosis. You will simulate the stages of mitosis by using chromosome models.You will use prepared slides of onion root tips to study plant mitosis and to calculate the relative duration of the phases of mitosis in the meristem of root tissue. Prepared slides of the whitefish blastula will be used to study mitosis in animal cells and to compare animal mitosis and plant mitosis.
Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common
Sport fishing offers some of the most thrilling and exciting water sport adventures. If you want to gain the maximum out of a sport trip, what you need to do is hire an expert fishing charter. These charters give you an excellent opportunity to enjoy your activity in the most exciting of sport waters and with the right kind of guide, you can be sure of catching the best fish.
The variables in this lab were different than the average science experiment. Instead of affecting the experiment to prompt different results, we just had F1 generation plants produce offspring so that we could study their specific traits. By looking at the variables, we can determine if they fit the Mendelian ratio and see if genes are linked on a chromosome.
Plants are organisms that can reproduce sexually through meiosis and create more cells through mitosis (Russell et al. 2013). For studying mitosis, the common onion is an ideal choice. Because it is easy for onions to germinate without soil, it is easy to control any substances provided to the plant. The onion root tips are only a few cells thick and grow quickly making them ideal for time efficiency. The onion root tip needs to be squashed between the cover slip and the microscope in order to reduce the slide preparation’s total depth. To dye condensed chromosomes, such as those undergoing mitosis, a stain is used to make
Ever since I was a kid I have enjoyed fishing. Fishing relaxes my mind and allows me to get away from the stress of the real world. From the cool breeze around the lake to the fishes nibbling away at the bait, it’s all just very relaxing. There was one day where I caught more fish than I had ever caught before. The entire day had been going my way. My boss called me and gave me the day off and that alone is a good way to start your day. After getting the day off I was able to get a few extra hours of sleep. Being able to sleep in allowed me to get the some rest that I had not been able to get for a few weeks. After getting my well-deserved rest I decided to go to the pet store to get some fish bait. Fishing was not my original plan for that day but since I was able to get the day off and I didn’t have any other plans I was able to plan to do one of my favorite things.
In contemporary society, human society is progressing rapidly on various fronts. Nevertheless at the same time, the problem of overfishing is becoming increasingly worrisome and attract extensive attention of the society. In this essay, I will address overfishing and propose some possible causes of this phenomenon which can give contribution to some solutions.
In this essay youll learn how to fish. People think they know how to fish until they start to fish and don't catch anything but sticks. When people catch sticks they tend to lose their temper. When this happens they normally just give up and leave without even trying to catch a fish. So here are the steps for fishing.
Commercial whaling is a serious world issue that has always been difficult for those who are in support and those who are against it. Each group defends their side with convincing arguments. Morally, whaling is wrong, but do the reasons for whaling outweigh the reasons to cease the primitive hunts? By studying the effects of whaling,realizing how culture has changed over time, and taking note of the money that would be saved, it can clearly be seen that there is no longer a current need for whaling to continue. Efforts have been made to try to stop whaling, but with no help from any authoritative figure,nothing has been done to regulate the whaling. The famous sea shepherd, known for its strikes against whaling, can even be seen on
Making the onion tip root cell slide was successful. Our results supported the hypothesis because we saw cells in the onion root tip in prophase, metaphase, and anaphase. As we went up in power objectives, each phase of the cell became more definitive. The cell root was a great indicator of the structures of the different cycles of the cell. This is important because we will be prepared for future labs working with the microscopes and can now adjust it for the best view of the slide. We practiced working with the compound light microscopes and different phases of the cell cycle. Onion root tips are useful to observe mitosis because the cells are frequently diving as the root grows. So when we stained the cell, we caught many cells in different phases. The significance of this lab was to better understand the process and stages of mitosis and meiosis and compare and contrast the mitotic process in plants and animals. We grasped the concepts of what the chromosomes look like, and what they look like in each step of the processes. Having read much about mitosis and meiosis, seeing these cells was the real application of describing and understanding the stages.
Overfishing is an enormous issue that needs to be corrected or there will be no more fish to catch in the future. The true definition of overfishing is as defined by the national fisheries act from 1996 overfishing is “a rate or level of fishing mortality that jeopardizes a fishery's capacity to produce maximum sustainable yield (MSY) on a continuing basis(kennedy, 2016)." Some of the facts of overfishing are so shocking they would blow you out of the water, as well as some of the effects overfishing can have on the fisheries. The solutions to overfishing are extremely simple and completely within our power to do.
Our family has rules set that say you have to be 10 years of age or older to go on our Canada family fishing trip. At our family gatherings I hear so many stories of how many fish that they caught. I am filled with anticipation to go with them and catch some of those great big fish. I have dreamed of the day now it is here I am ready to go, my bags were packed, the boat all clean and off we went.
