Experimental Design Lab

Title: Factors affecting the enzymes reaction rates Purpose: Observing the differences in the reaction because of the different concentration of enzymes Hypothesis: Higher concentrations of lactase drops will react stronger to the milk. As more lactase is put into the milk, the glucose concentration should be higher. Materials: Five Test Tubes Beaker or Graduated Cylinder [Lactose] milk Lactase Glucose test strips Introduction: In this lab we will be adding the lactase enzyme to…

DNA Protein Synthesis-Transcription and Translation

Transcription:  1. How is mRNA different than DNA? mRNA has one strand whereas DNA is double stranded, meaning that there are two sides which join together. mRNA’s job is different to DNA’s because it is supposed to copy the info of the DNA strand. After that, the mRNA moves to the cytoplasm to help build protein. Also, DNA uses the base thymine whereas mRNA has the base uracil. Finally, DNA…

Diffusion in Agar Cubes

1. In terms of maximizing diffusion, what was the most effective size cube that you tested? The cube which was the most effective in diffusion was the smallest cube. Nearly the entire volume of the cube turned pink from the diffusion. 2. Why was that size most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissues? It was the most effective…

DNA and Protein Synthesis

1. Explain the structure of DNA.  DNA’s structure is made up of sugars, phosphates and nucleotides. The sugars and phosphates form the antiparallel strands that nucleotides hold onto. There are 4 different nucleotides in DNA; adenine, guanine, cytosine and thymine. Adenine and guanine make up the group of purines which have a complimentary base pairing  with the pyrimidine group, consisting of thymine and guanine. 2. How does this activity help…

What Darwin Never Knew

The fact How did the discovery of DNA prove that Darwin’s theory of evolution was correct and how does it change the way we view evolution today and into the future? Although Darwin didn’t have any evidence to prove his theory of evolution. His theory explains that all animals come from the same prehistoric animals, which were fish. Over time, all animals adapted and mutated to create new species that…

Exploring Quadratic Functions

1. A quadratic equation is used in at least one variable and the highest-degree term is the same as the second degree. 2. Give an example of a quadratic function and give an example of a function that is NOT a quadratic. An example of a quadratic function is and an example of a function that isn’t a quadratic is y= 2x + 1 3. Either side of the parabola…
