Blog #12 - Worm's Dissection

What surprised you from the worm's dissection?


There were several things that surpised me from the worm's dissection. One thing was that I did not expect the worm was going to be that long. I though that the worm was going to be like an inch long. Another thing I was surprised was the worm's head which including the brain, which was pretty interesting to see. Another thing is I did not expect the dirt in the worm to still be inside it. I thought it was diggested already. All the parts in the worms head was very interesting to see. Overall the worm dissection was pretty interesting to do because I got to discover the parts of how a worm lives or is.

Blog #11 - Alternation of Generations

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


Sexual reproduction involves the two alternating processes of meiosis and fertilization. In meiosis, the chromosome number is reduced from the diploid to the haploid number. In fertilization, the nuclei of two gametes fuse, raising the chromosome number from haploid to diploid. Meiosis generates the haploid gametes, sperms and eggs, directly. These single cells fuse to form the zygote which will develop into another diploid animal.  In most plants, meiosis and fertilization divide the life of the organism into two distinct phases or generations.

Blog #10 - Dissection

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


Dissection is an important part of biology curriculum because it helps people observe an inside of a flower, animal, and etc. This way people would find out more about the thing. People would know more information on it and they would learn something new of what is inside of the thing. Animals that should be included in biological studies are frogs, worms, and flies. Plants that should be included in biological studies are roses, tulips, and sunflowers. This way students in school or people outside could find out more of how a these animals or plants lives or reproduce in their lives.

Blog #9 - Forms of Community Interactions

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

Competition is when organisms of the same or different species attempt to use an ecological resource the same place. An example of competition are the resources such as food, space, water, and etc. Commensalism is the relationship in which one species benefits, while the other is neither harmed nor benefited. An example of commensalism is when commensal species usually employs host species as  a home and/or transportation. Mutualism is an interaction that benefits both participants.  An example of mutualism is coevolution. Predation is an interaction in which one organism captures and feed on another organism. An example of predation is when interaction clearly positive for the preadator but negative for the prey. Parasitism is a parasite or disease that uses host for food, but does not immediately kill the host. It kills it slowly. An example of parasitism are Giardia lamblia, Dermacentor Andersoni, Hookworms, Pediculus humanus, Dirofilaria Immitis, and Mosquito.
