Indian Removal Act: Research Simulation Paper The Native Americans had lived in America for generations. They were already here when the colonists came from Britain. Colonists survived because of the Native Americans’ help. When the colonists fought the Revolutionary War‚ some of the Native Americans allied with the British‚ but some fought on the colonists’ sides. Britain armed some Native American tribes to fight against us in the War of 1812‚ but some stayed with us the whole time. Settlers wanted

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each
Premium Heart rate
The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye
