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!
