What was your favorite topic this semester? Why?
What was your least favorite?
What would you change about this class if you could?
What do you feel is your biggest accomplishment in biology this year?

1) My favorite topic in this semester was ecology because it expanded my knowleged on the natural world.
2) My least favorite topic was dissection. I have no interest in exploding the external and internal parts of organisms.
3) I would prefer study from our biology text book instead.
4) My biggest accomplishment in biology this year was maintaining an A throughout the semester.

Endanger Species - Panda

     I am a Panda,  and I am a symbol for international wildlife conservation since 1936.  Unfortunately, I am in a serious problem right now.  My favorite food, bamboo, is getting less and less, it will be hard to find any food for me and my friends to eat.  As a result, bamboo takes about twenty years before it can support our population.  We keep moving to new areas to search foods.  We afraid that we might die of starvation someday. 

     Even though we want to have babies, it's hard for us to find a perfect mate since we are a little picky about choosing mates.  However, we are slow to reproduce too.  Furthermore, many people are trying to kill us and sell our furs.  That's why we are near extinction line.   So, please save us!

Virtual worm lab

Parts of a worm

nternal anatomy of an earthworm (lateral section): small, long, cylindrical animal without legs or hard body parts.
Mouth cavity: entrance to the digestive tract of an earthworm.
Pharynx: part of the digestive tract of an earthworm just after its mouth.
Ventral nerve cord: set of nerves in the abdomen of an earthworm.
Seminal receptacle: pocket related to the semen of an earthworm.
Ventral blood vessel: blood vessel situated in the front part of an earthworm.
Nephridium: organ of an earthworm that performs the functions of kidneys.
Gizzard: pocket used as the stomach of an earthworm.
Dorsal blood vessel: blood vessel situated in the rear part of an earthworm.
Crop: bulge of the esophagus of an earthworm.
Seminal vesicles: small hollow organs that carry the semen of an earthworm.
Lateral heart: blood-pumping organ of an earthworm.
Esophagus: part of the digestive tract of an earthworm between the pharynx and the crop.
Brain: brain of an earthworm.

parts of a flower

           an imperfect flower does not have a male and female part in the same flower.

           a perfect flower contains male and female reproductive systems.

           a complete flower is a perfect flower that has petals and sepals.

a flower lacking one or more of the four parts found in a complete flower: sepals, petals, stamens, and pistils

Biogeochemical cycle

Biogeochemical cycle connects with biological, geological, and chemical.

Bio: Living things are involved in the cycle.  The cycle might limit the organisms on earth.
Geo: Rocks, nonliving things, and evironments are part of the cycles.
Chemical:  oxygen, carbon, hydrogen, and nitrogen cannot be used unless the elements are in a chemical form that cells can take up.

Ecological footprint

BOW Go to http://www.myfootprint.org/ and calculate your ecological footprint. What are some areas that you can improve in?


My ecological footprint is 4.64 Earth.  I can improve it by shorten the shower time since I usually took more than 30 minutes for shower.  Lowering my shower time to 20 minutes can save water.  Also, I should turn off the light when no one is in the house or my room.  I often left the lights on at night.  Furthermore, I should recycle all the bottles and papers.
