TSOTS Assignment #7

This is a picture (40x) of the carpel. It consists of the ovary and a stalk called a style with a sticky tip called a stigma. Pollen grains get stuck on this sticky tip. If you look you might be able can see a yellow dusting of pollen on the stigma in the picture.

This is another picture (40x) of the carpel but it is split in half. As you can see the inside of it is a lighter green, this is because that is where the sticky residue that catches pollen grains is produced.

This is a picture (40x) of the stamen, the male reproductive part of the flower. It has a stalk called the filament which comes up from the base of the flower. At the end of this stalk is the anther, which produces pollen grains that contain the plant's male gametes.

GATTACA Quote Response

"You wanna know how I did it? This is how I did it Anton. I never saved anything for the swim back." -Vincent

      This quote from the movie, in my opinion, means that you should not wait for the last minute to do something. Also I think this quote means that whenever you do something, you have to give it all you have. Vincent tells Anton this whey are playing the game called chicken, where they swim from shore as far as they can without turning back, which is when you lose because they have got scared of swimming into the sea. Whenever Vincent and Anton would play this game, Anton would always win because Vincent was born an in-valid. The last two times they played the game chicken, Vincent finally won. On the last time they played chicken, Anton ended up drowning and was saved by Vincent. Vincent brought him back to shore and they never again played this game.  

Ryann's seed story (by Henry posted by Ryann)

Ryann has learned more about gardening than she had before and that plants can survive in very diverse conditions. What surprises her was that everyone in our group worked like a well oiled machine and got along great. What made her laugh was our team name "pots" because we asked James to bring in some pots to plant our plants in and the "pots" that he bought were these really tiny plastic pots. Things that made her pause an think deeper were how the plants grew faster in the sand rather than the soil and how to get the best results out of this project. Some of the questions that she had were; How did the plants survive in the sand but not in the soil? And What could we do to make the project better?

Henry's seed story

Henry has learned that working together as a team and cooperating constantly is vital. He was amazed and surprised at the fact that people actually worked in our group. Like me what make Henry laugh was when James brought the "pots" which were these tiny little plastic pots. These "pots" resulted in the creation of our team name pots. Something that made him pause and think deeper was how could he make himself as efficient as possible for our team. A question that Henry had was how can such a small environment contain such an amazing ecosystem?

Responses to NOVA: Evolution Web Quest

PBS:NOVA, Revealing the Origins of Life 

   Chemistry is a major part of how the earth and the beings on it were created. Through chemical processes that formed parts of the RNA such as the phosphate and half of the nucleic base containing genetic information and then the process of evaporation started the recipe for life. The hybrid of RNA would fall from the sky, meet the other half, and then connect and form the RNA helix. Light would then hit the ribo-nucleotides and change the C base into U.


A Neanderthal Burial 

   In the video, there were many skeletons found but one stood out to the researcher. It was that of a young female. She was positions as if asleep but that didn't make sense to the scientist. What they once believed was the site of a cave in, they now think is that of a burial place. The girl had a panther paw next to her and scientists hypothesize that this is a trophy for hunters, much like that of bear hunters cutting off their claws.

Evolution Web Quest

Chemistry was a major role in how Earth probably began. Through chemical reactions that formed some RNA is how single cell organisms were created. This RNA had the base of C and when in sunlight it created the RNA strand with the base of U. This RNA created the basis for life on Earth.

Article: Evolution of Laughter

Laughter is a key to survival for babies. It makes adults get on babies side or pay attention to them. Laughter binds people together by creating a bonding moment. Laughter is not only used by humans it is also used by gorillas. it first comes from the arangatangs then the movas then human babies. Laughter connects people together because everyone can laugh.

Interview: The DNA of Human Evolution
In this interview Katie Pollard explains that she has been curious about what makes people human. So to figure this out she is bringing in new types of data and machinery into her lab. When she first started to study human evolution her team had access to artifacts and bones which they dug out of the ground. Then they observed the earth today and how they would have lived back then. Later she began to compare human DNA to chimp DNA since they are out closest relative. When she finished her studies she found out that the human and chimp genome lined up. She ended up finding that sequencing of humans and chimps were very close to each other. 

Anthers and Stigmas and Styles (Blog Post Assignment #7)

       

This is a picture (40x) of the stamen which is the male reproductive part of the flower. It has a stalk called the filament which comes up from the base of the flower. At the end of this stalk is the anther. This part of the stamen produces and releases pollen grains, that contain the plant's male gametes. This is a picture (40x) of the carpel. It consists of the ovary and a stalk called a style with a sticky tip called a stigma. Pollen grains get stuck on this sticky tip. If you look you might be able can see a yellow dusting of pollen on the stigma in the picture. This is another picture (40x) of the carpel but it is split in half.
