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

Alternation of generation refers to life cycles where organisms have two different multicellular stages: one that is diploid, another that is haploid. This is different from human, humans are multicellular stages are usually diploid. The only time when its haploid its egg and sperm. Haploid is a cell or an organism having half of the number of chromosome in somatic cells. In the other hand, diploid means a cell or an organism consisting of two sets of chromosomes. Alternation of generation could also represent the life cycle of plants. The picture represents an example of alternation of generation. It is both multicellular diploid and multicellular haploid. On the undersurface of its base or leaves, it goes through meiosis to create haploid cells.  

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

Many people thinks dissecting animals is like slaughtering animals that are alive, but they're wrong. Many dissections doesn't involve spilling of any blood. People uses dead animals for dissections, to eliminate the need of killing million innocent animals. Dissections increase students' knowledge of biology, and also provides new information for the scientist. Nay sayer’s of the virtual dissection technique believe that the students will not receive the same level of instruction and understanding from dissecting animals on the computer. Many schools still continues to use real animals instead of computer, because of the cost of the program is too expensive.

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

Competition is a contest between individuals group of animals for their territory, or a location of resource. Such as food resources. One example of competition is when different species of fish were inside the same fish tank. One will attack the other to eat, and produce stronger species. Commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral.An example of commensalism is a flatworm attaching to the horse crab and eating the crab's food while the crab is unaffected. Mutualism is when two organisms interact with each other and both derives a fitness benefits. One of the example for mutualism is when many ants are found in the vicinity of aphids. The ants feed on the sugary fluid released by the aphids, and the aphids are protected by the ants. Predation is a way of life that stronger animals attack weaker animals and eat to survive. Example for predation is when hunters are hunting for birds. Parasitism is a type of relationship between animals that they both get benefits from eachother. An example of parasitism is a flea and a dog. The flea sucks blood from the dog and so the dog is harmed.
