 Write a letter to Senator Feinstein describing what alternative energy source you think we should be pursuing. Give at least three reasons why.

               I think a new alternative energy source we should pursue should be solar energy. Solar energy would help ensure our survival more efficently in an economically better way. Compared to fossil fuel or nuclear energy it doesn't really affect us as much. Solar powers are based on biomass,wind, solar,geothermal, and hydroelectic energy. The windmill, for example are good alternative for fossil fuel and are also cheaper than the new electric generation. Another commonly used power would be the solar panals.Solar panals convert light to electricity which applies to other materials using this alternative. Such as solar calculators,water heating, furnances,boilers, and more. Sloar power would also be continously spread and used for more objects.
            So, solar energy would be better to our enviroment, cost less, and is spreading to adapt to human needs

 What was most interesting about this week's dissections?

In the fish dissection I found the swim bladder interesting. It's dark apperance stands out and is pretty large in size. I thought it was part of the liver because the liver is pretty dark but its not. The cell membrane also well protected the eyeball. When we poked it accidently, water would come out. I alos never knew that a fish have two types of bladders: a gallblader and a swim bladder.

 What surprised you from the worm's dissection?

 To me, I was suprized when we dissected the head part. I was able to seee the brain and heart. I was able to dissect the worm by counting the number of lines. I first cut the part from the anus to the clitellum and used pins to stick at a 45 degreee angle to observe the blood vessels and the intestines. Then carefully cut to the mouth to observe the gizzard, heart, pharnyx, brain, ovary, nerve cord, and ect.

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

During animal life cycle, animals are expected to give out eggs and sperms to reproduce. Likewise plants does too but is reproduced through stages, or generation. As the diagram illustrate, the adults have to produce spores, which the spores then produce sex cells. There are two generations:sporophyte ( spore producing plants) and gametophyte(sex-cell producing cells).The two generations can be differentiated by the chromosomes they carry.

In the spores generation, only one parent is needed to create an offspring with the characteristics it needs to survive.  In sex parents, both give their characteristics  causing a mix. This however can be a benefit depending on their environment. For example, mosses are used as a primitive group. The sporophyte are clearly shown on the stalk representing the location, spores are caste on top. The gameotophye are on the bottom. The stalk connected to the gametophyte creates the egg. Water would be necessary to complete it.
