Cockroaches in the dorms may be a genuine nuisance, but the prepared BIOL 1114 student understands their nature quite well. You notice on a chilly morning, as the temperature of the dorm begins to rise, smaller cockroaches become active sooner than the larger ones.

In a sealed jar of cockroaches, CO2 increases and oxygen (O2) decreases.

Tilapia are freshwater fish that can be raised in tanks as food fish in aquaculture facilities. Scientists are interested in increasing the growth of Tilapia and want to find out which diet results in the greatest fish biomass (weight) gain. They test duckweed (a plant), algae (a single-celled photosynthetic organism), or a combined diet of duckweed and algae.

Wilson Beagle has decided to attend this year’s Beagle family reunion and has been asked to bring a new and exciting dish! He decided to bring a new dog food. It contains Puppy-Energy 4000, a chemical that is supposed to increase ATP production by causing the Electron Transport Chain to produce a higher than normal proton gradient. Wilson’s cousin, Dan, wolfs down this new and delicious kibble (treat). Wilson notices the new food causes Dan to struggle with his energy level and soon his health deteriorates. To save Dan, Wilson must figure out how the new chemical is affecting Dan and reverse its effects!

Recently, Barry Allen became a super-hero with the ability to run at super-human speeds. Barry needs to eat a large amount of food each day to keep up his energy levels. Fascinated by his powers, Dr. Wells, a local scientist, decides to experiment on Barry to find the origin of his powers. Dr. Wells decides to test Barry’s cells to see how they respond to a variety of environments. To test this, Dr. Wells places samples of Barry’s cells into solutions of higher, lower, and equal salt concentration.


You just moved to Stillwater to attend OSU and are renting a house with two other housemates. All three of you have brought pets: a dog, a cat, and an iguana. Since you and your housemates have different class schedules, you decide to get organized and share the responsibilities of caring for the three pets. The dog is the largest animal and needs to be walked twice a day. The cat is small, usually sedentary and likes the comfort of a warm home. The iguana is about the same size as the cat. ”
