Stride Rate and Length Although strides vary greatly among runners‚ a few studies have worked to quantify differences in stride rate between barefoot and shod runners. They have concluded that an elite shod runner usually has a stride frequency between 170-180 steps per minute even at low speeds such as 2.75 m∙s-1. On the other hand‚ nonelite runners often fall in the range of 150-160 steps per minute at similar speeds. Barefoot or minimally shod runners are often characterized by shorter strides

Life story on the man behind genetics Johann Gregor Mendel was a biologist and ordained priest who conducted experiments in heredity. He used his resources at his monastery to grow thousands of pea plants‚ keeping detailed records and calculations that debunked the previous theory of “trait blending.” Although people largely didn’t recognize his work during his lifetime‚ his lengthy research showed that characteristics can be dominant or recessive and are passed on independently. These facts transformed

Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine

Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences.
