Final blog

            In Biology, I was able to achieve a more hard working statis. It gave me dozens of work that made me felt like a working man and that i allowed me to be satifsfied since doing work gave me appreciation of myself and my abilities. Although Ive done well in homework, I've done incredily bad in benchmarks. Benchmarks were not easy for me since it required alot of studying time which I was incapable of doing. However whether i succeed or fail in Biology, I will always remember the experience that i have learned in dissections. The dissections were actually quite intirguing and fun while at the same time enabling me to anticipate even more for it every week.

Blog 15 Compare two of the organisms that we have dissected Discuss at least 2 similarities and 3 differences

                            Both the frog and the rat were eerily similar to each when disssecting. They were both very difficult to cut open. The frog and rat had internal skeletons, but were still diffciult to cut. However, the rat had hair all over it and its was definitely even more strange when it had preservatives on it. The frog was only covered in slime and gave off a very disturbing aroma.

Blog 14 Compare two of the organisms that we have dissected Discuss at least 2 similarities and 3 differences

                             Both the crayfish and the grasshopper have similar outer hard shell and antennas attached to their heads. However there are many other differences between them. Their differences would be that Crayfish are classified as decapod crustaceans. This is the same familygroup of invertebrate crustaceans that includes prawns, lobsters, crabs and shrimp. Crayfish are also readily identifiable by the large set of pincers that stretch out in front to help them find and eat food. On the other hand, Grasshoppers have a body divided into three parts: head; thorax; and abdomen. Three pairs of legs grow from the thorax. Grasshoppers possess a sturdier set of front wings that protect the rear wings from accidental damage. Grasshoppers are herbivores that often eat vegetation indiscriminately.

Blog 13 What was most interesting about this week's dissections?

                         This week's dissection had crayfish and worm. Much to my surprise, a worm has many aspects relating to humans. Their organs seem awfully similar to us, but of course, lack in size. The amount of organs were not alot. Their smell were from urine coming out of their skin. Crayfish ,on the other hand, is also very similar to the worm. They both have to rely on sense of touch since their visions are not very well, but what they lack in vision, means enhanced senses.

Blog#12 What surprised you from the worm's dissection?

                       Dissecting a worm had never been so gruesome. I clearly had no idea that dissecting a worm would involve peeling both sides of its skin off. Next thing you know, huge gushes of mud pours out from its interior and an aroma starts to consume the air. No longer could I stand it, but I convinced myself to get over with it and complete this difficult dissection. I was able to witness its organs, brains, and its heart actually very much resembled a human one.

Blog #11 Get a picture of alternation of generations put it in your blog and explain how it relates to plants

                       All plants undergo a life cycle that takes them through both haploid and diploid generations. The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic division. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations. The way in which the alternation of generations occurs in plants depends on the type of plant.

Blog #10 Why is dissection an important part of a biology curriculum? Which animals and/or plants should be included in biological studies?

            Dissection is incredibly important because it allows to closely examine the internal parts of an animal to learn the ways of anatomy. Since anatomy has been around for over many years, dissection is very helpful to teach the younger students in how animals are designed and closely related to the human anatomy. The animal that should be more included in biological studies should be insects. It seems insects are barely used in the biology curriculum and can be very much examined if give more of a opportunity. More dissections of insects could further increase the understanding of them for more people.

Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each

                    The competition for resources such as food, water, territory, and sunlight results in the ultimate survival and dominance of the variant of the species best suited for survival. A limited amount of resources are available, and several species may depend on these resources. In ecology, commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral. An example of commensalism is cattle egrets foraging in fields among cattle or other livestock. Mutualism is the way two organisms biologically interact where each individual derives a fitness benefit. A well known example of mutualism is the relationship between ungulates and bacteria within their intestines. predation describes a biological interaction where a predator feeds on its prey. Parasitism is a type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host.

Blog 8 Your choice talk about something you learned or ask a question about something that is confusing you

                          For the past semester, I know what've I've got to do. It is to concentrate and exceed other people's  expectations and mines also. I will do this by working even more harder than ever before in my life. Taking time to read more and study more is what can do to bring myself back in the game. Hopefully, this goes well and i finally realize my prevoius mistakes since after all I am starting on a road to redemption to prove myself that anything is possible!

Blog 7 Compare and contrast two biomes describe them in detail include pictures of plants and animals you are liklely to see

                        The reliance between aquatic and terrestrial biomes are unmistakenable, Earth's different aspects of life are all unified with one another. Aquatic and terrestrial biomes have a unique dependence towards each other, effecting weather, climate, organisms and other countless characteristics relying on one another. In aquatic biomes, it holds a large close tie with the surrounds of a terrestrial biome. As seen vividly throughout the vastness of earth, biomes dominate the existence of life and provide a community where living organisms and place diversify among species. Aquatic biomes have a life zone that can be seen in early earth, from there, terrestrial life evolved and developed into the existence that we see today.

Blog #6 Which level of a food pyramid is the most important?

                  The most important level of a food pyramid is the meat group. The meat group is one of the major compacted food groups in the food guide pyramid. Many of the same nutrients found in meat can also be found in foods like eggs, dry beans, and nuts, such foods are typically placed in the same category as meats, as meat alterantives. Although meats provide energy and nutrients, they are often high in fat and cholesterol , and can be high in sodium. Simply trimming off fat can go a long way towards reducing this negative effect. The food guide pyramid suggests that adults eat 2-3 servings per day. One serving of meat is 4oz, about the size of a deck of cards.

Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?

                    If humans are actually impacting the 6th major extinction, there is a sure chance it is because we are putting hazardous materials in other animals' ways. Many trash are being eaten up, even attached to,  by birds or sea animals in the sea and that is a very serious issue that can cause many innocent animal lives. Another is the slaughtering of the animals to produce the selling of meat, but it surely cant be done since it is surivival of the fittest.

Blog # 4 Describe the three types of selection: directional, stabilizing and disruptive and give an example of each in your own words

                     Directional Selection occurs when selection favors one extreme trait value over the other extreme. It ususally happens in the mean value of the trait under selection. A Disruptive Selection occurs when selection favors the extreme trait values over the intermediate trait values. In this situation the variance increases while the population is seperated into two different groups. It plays an important role in speciation. Stabilizing Selection happens when selection favors the intermediate trait value over the extreme values. Populations under this type of selection can usually go through a decrease in the amount of additive genetic variation for the trait under selection.

Blog #3 Explain what microevolution is? What are the three ways that variation occurs?

                   Microevolution is the change in allele frequencies brought about by mutation, genetic drift, gene flow, and natural selection. One of the ways that variation occurs is when mutations alter the order of bases in the nucleotides of DNA. Mutations can most definitely be rare and most mutations are probably harmful, but in a few instances the new alleles can be chosen by natural selection. Independent assortment and the Crossing over that happens during meiosis are two other ways that variation occurs.

Blog # 2 Why is fossil record hard to interpret?

         Fossil records are hard to interpret because fossils are often poorly preserved and hard to interpret. For example, identification is hampered by a lack of fossilized gonopods, which may be because the fossil forms had a primitive form of sperm transfer, or the fossils are immature animals. A similar problem is encountered when trying to establish whether differences in numbers of legs and segments are true differences.

Blog #1 Why is evolution a theory and not a law?

                       In science, a theory is an explanation. Where a law is a pattern that natural phenomena follow. So they're two different things. A law is great for predicting events, because we expect the events to follow the pattern. But the law won't explain why events follow the pattern. For that we need a theory. Both theories and laws can turn out to be wrong, and must be tested by considering what evidence we should find if the theory or law were false, and then looking for such evidence.
