My Sunflower Plants

Here is my final picture of my sunflower plants. I was given two seeds, both seeds sprouted and grew. They were first under a lamp in my room until they got to a point where i had to put them on my windowsill because they were too big. they were watered two times a week. One plant has grown to  18 inches, the other 10. The smaller one is in process of blooming right now and the larger one is about to start.

Population Life Tables

The tables below demonstrate the survival rate of humans throughout time. This table demonstrates the survival rate of a species over time. Humans tend to live a longer time and die off rapidly near 70 to 80 years. In contrast a type of tree such as an oak will have a quick die off period initially and only a few will survive the longrun.


As you can see most humans survive early on, once the time gets to about 80 years the line tapers off quickly.

Another interesting chart I discovered compares the population life tables of humans over a couple centuries. you can see the drastic effects of health and well being over the past couple hundred years.

Making bio-diesel and bio-ethanol

Bio diesel and bio ethanol are currently considered as the future of fuel for vehicles, other heavy machinery, and power in general. The process has many steps and is currently costly. The idea is to take used oil or to take corn or plant matter and break it down into diesel fuel or  ethanol, depending on the material. Bio deisel requires the use of old grease or vegetable oils. below is a chart of the step required to make bio diesel.

This process, if streamlined, can drastically reduce the need for fossil fuels. Bio ethanol has a similar method but requires plant matter such as corn or reed. Below is a diagram of a typical bio ethanol plant.

 

Both of these method for producing alternative fuels are a good start to finding alternative energy. Bio ethanol runs into problems because it cuts into corn supply, which is a major food source for the whole world, which in turn has negative effects on the economy. It will be interesting to see where future of alternative fuels takes us.

Mitochondrial Eve

Mitochondrial DNA is a replication of the the DNA from the mother. All mitochondrial DNA comes from the mother is replicated and not changed. This means that the same DNA code has been passed down from mother to mother since when humans first walked the earth . Scientists estimate this woman lived from 150 to 200 thousand years ago. 

Mitochondrial DNA only makes up .001% of our DNA, but it is the only DNA that is not in the nucleus. The mitochondria are the powerhouse of the cell. Any they are inherited from the mother.

Amphioxus

The amphioxus are members of the invertebrate subphylum Cephalochordata of the phylum Chordata. they are small, fish-like creatures. generally less that 3 inches in length.  They are not particularly good swimmers though. Although they have no defined head and no eyes, they are closely related to vertebrates. They feed off of food particles in the water

They are generally found in the mud, sand, or gravel at the bottom of the ocean. They are found in access off the coast of China. They are also commercially fished. Below is a diagram of an amphioxus.

Macon Dog Park

For this lab we were supposed to go visit the dog park in Macon and take examples of the creek water to examine the bacteria content. Unfortunately, when we got halfway to the dog park it started raining so we turned around. We were told to discuss the dangers of bringing a young dog, or an unvaccinated dog to the park because of the ease of spread of disease. This holds true, unlike humans, who are in contact with multiple humans on a regular basis. 


Dogs are not brought together often, with the exception of a dog park. this means that many new diseases, or fleas, are introduced to your dog every time you bring man's best friend to the park. Your dog (especially the youngest) doesn't have the immunity for all of the new diseases it is introduced to. Causing a health hazard for your dog. 

Darwin's Dilema

For one of our labs we watched a movie about Charles Darwin's struggle with Precambrian period fossil records. The Burgess shale, located in Canada, is an archaeologist, and paleontologist's  playground. The layers in the shale demonstrate species evolution from all the way back to the Cambrian period.


Darwin's struggle is that, before the Cambrian period, there are no longer fossil records of life. The movie suggests that all life came to be in a matter of about two minutes. This, to me, seems to help further prove the fact that there is an intelligent creator although Evolution may have occurred and still be occurring.


This movie gave me evidence towards my beliefs. I respect Charles Darwin for his many contributions to the scientific community but at the same time I disagree with his view on the beginning (or creation) of life. His dilema in this movie only further proves my case. If he were alive today, It would have been interesting to talk to him to see his views.
