Bio Entrepreneurs

In China there is a compony called Sunhy Biology Company. They are well known for selling modern bio technology stuff including:

• enzyme


• phytase


• chemical


• veterinary


• antibiodics


• premix


• acidifer


• choline


• chloride


• vitmin C


• ferrous fumarate

I believe that this company will be successful because of all the products they sell and how they are trusted by many people.

Eye Lecture

We had a guest lecture named Dr. Pamela Fong where she taught us the eye anatomy.

the basic anatomy of the eyes is...

• iris- the colored part of the eye



• pupil- controls how much light enters the eyeball



• cornea- focuses the eyes



• lens- focus light onto the back of the eye



• retina- a fine line of tissue that lines the inner part of the eye



• optic nerve- transmits impulses from the retina to the brain

Dr. Fong also told us facts about the eye usual people do not know.

• You are able to tell if a person has high cholesterol or blood pressure
• people with different color eyes have different retinas
• everyones eyes differ
  
  

Animals stuck in time.

Recently, William Roberts and his colleagues from Western's Pychology Department studied the research of animals being able to tell how much time has past but not able to recognize past or future. The idea to study this came from realzing that dog owners notice that their dog seems very happy seeing them as five minutes away to five hours. The animal they used to do research was a rat. Once studying the rats the scientists realized rats were able to keep track of how much time passed since they were fed cheese as well as the size but were unable to place the memory in a time.

I think that that is just weird. I never really thought of an animal having a different mind then how a human has one.

Guest Speaker

On January 24, 2007 we had a guest speaker come into our class and talk about evolution as well as Darwins theorys.

She questioned if Darwins theory was correct or incorrect but truthfully all the evidence it too overwhelming.

The following evidence for evolution is:
Biogeography
Comparitive Anatomy
Molecular Bio
Fossil Record
Developmental Bio

Biogeography: the distribution of plants and animals where they are located and placed in the world.

Comparitive Anatomy: Common ancestory

Molecular: Human [homo][46 chromosomes], Chimpanzee [Pan][48 Chromosomes], Gorilla [Gorilla] [48 Chromosomes], and Orangutan [Pogo] [48 chromosomes]

Developmental: Often find the same gene in different animals. Lots of documentation.

Fossil Record: Shows the changes over time and what came first and so forth.

Bees

Domain: Eukarya

Kingdom: Animalia

Phylum: Arthropoda

Class: Insecta

Order: Hymenoptera

There are around 400 different species of the bumblebee including bumblebees, Stingless bees, and honey bees.

The importance of bees is for cross-pollination and many plants are depndnt on the bees to help it reproduce; for example the red clover or orchirds.

Bees are described by their enlarged hind feet which are usually equipped with pollen baskets of stiff hairs for gathering pollen. Bees feed by pollen and nector which is converted into honey.

Solitary bees are reffered as a carpenter, plasterer, leaf-cutting, burrowing, or mason bees because of the material or method the bees use to construct nests for their young.

Marine Bio

It is predicted that over the next 70-100 years that sea temperatures will change 3 degrees C. Researchers have tried to understand how Global warming will change the fish species near Denmark. While doing so researchers have found a total of 180,000 fish bones. Most of these fish bones were Anchovey and Black Sea Breem. They noticed that the species decreased when temperatures have lowered and that the species has reappeared now that the temperature has risen a little bit. This has become a shock because this changes the life expectancy of the Cod Fish. It has been shown that their species has been decressing more. I think that this is shocking becuase it doesn't seem like old fish bones would do anything. What i also don't get is how can a species that has died over time reappear? it just seems weird.

Trees

Recently Cornell Archaeologists have been studying old tree rings and Ancient wood. The scientists are using dendrochronology to examine the trees. Dendrochronology happens to be the study of comparing growth patterns in the tree trunks to date past events or climate changes. Cornell's lab holds more than 40,000 tree trunk samples.I find it so interesting because it goes further in science with dating what has happened and where. For example, they can precisely date Hammurabi, when Santorini volcano errupted, and the Bronze and Iron Ages. Along with many more recent events.
