Blog #8:Your choice talk about something you learned or ask a question about something that is confusing.
The one thing that confused me was the Skulls. The experiment/activity that we did when we had to measure them. It was confusing on how to measure them and if we did know how to measure them we didn't know what to do next. I didn't know what part of the skull to measure since it would probably give different measurements. That was one of the experiments/activity's that were confusing to me.
Blog #9: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.
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 important because it lets the people who want to learn about what the animal has in the inside of it or something they can't see and really want an answer about it. They should be studied since no one really knows what they have inside their bodies and it would be really interesting to see what they have inside their bodies. Their are beautiful flowers and plants in the Forest that no one has ever seen before and no one might not even know their characteristics. They should really be studied to see what they have or even if they can cure an illness.
Blog #11:Get a picture of alternation of generations put it in your blog and explain how it relates to plants.
The alternation of generations relates to plants because it is a term that is used in describing the life cycle of plants. This treats the alternation of multicellular diploid forms of plants with a multicellular haploid form as the defining characteristic.
BLOG #2:WHY IS THE FOSSIL RECORD HARD TO INTERPRET.?
Fossil record is hard to interpret because the animal is small. But also because the hard painstaking sand is covering the fossil. It is very hard to interpret a fossil without breaking it. When interpreting a fossil, the paleontologists have to find all the fossils of the animal. It is sometimes hard and sometimes easier, but doesn't mean it is easy. It is just a bit simple. It is very hard to interpret when it is a small animal because the bones of the fossils are very tiny. But when interpreting a large animal, it takes very long, but is somewhat easy, but it is still hard because they have to make sure not to break any of the fossil when interpreting it.
BLOG #3:What microevolution is? What are the three ways that variation occurs?
Microevolution refers to any evolutionary change below the level of species. It also refers to changes in the frequency within a population or a species of its alleles (alternative genes). Mutations alter the order of bases in the nucleotides of DNA. Mutations are likely to be rare and most mutations are probably harmful, but in some instances the new alleles can be favored by natural selection independent assortment (recombination of chromosomes that occurs during sexual reproduction) and the Crossing over that happens during meiosis.
BLOG #4:Describe the three types of selection: directional, stabilizing and disruptive and give an example of each in your own words
Directional: relating to direction toward a goal, "he tried to explain the directional trends of modern science."
Stabilizing: trying to get stabile from when it wasn't stable, "The atom is trying to stabilize."
Disruptive: causing damage and not being behaved. "The animal that is being testing is being disruptive."Thursday, April 14, 2011
