If feeding efficiency and reproduction have a direct correlation, and a population started with equal proportions of individuals with each of three feeding types, metal spoon, metal knife, and plastic fork, the frequency of the population with metal spoons as their feeding structure will increase in the next generation. While the frequency of metal knifes and plastic forks will decrease. Furthermore, since the organisms with the metal spoon feeding structure have a higher fitness level, this population will evolve by natural selection to a point where the metal spoon phenotype will be in abundant. While the organisms with metal knifes and plastic forks phenotypes will decrease in frequency due to the lack of reproduction. Eventually, if this population persist overtime, most of the organisms, if not all, will have the metal spoon phenotype, while very few, if not any, will have the metal knife or the plastic fork phenotype.

Based on the data, the number of pill bugs on the dark side is higher at almost every minute compared the number of bugs on the light side. In the beginning, the pill bugs are evenly spread out on both sides. However, as time goes on, the number of pill bugs on the dark side increased rapidly, while the number on the light side decreases. Based on the graph, starting at about three minutes, the number of bugs on the dark side begins to increase significantly. The pill bugs quickly react and choose a best fit environment for themselves. Eventually, at nine minutes there are nine pill bugs on the dark side and only one on the light side. At the end of ten minutes, all ten of the bugs are on the dark side. If the experiment went on for a longer

The solutions are 0% sucrose, 10% sucrose, 20% sucrose, 30% sucrose, 40% sucrose and an unknown sucrose concentration. We then weighed each egg separately to the nearest gram in order to have an initial starting weight to compare to the results throughout our experiment being conducted. The eggs were then placed in each beaker for 12 intervals at a time. After every 12 minutes the eggs were taken out and weighed to see if the weight of the egg changed. With a total of five intervals (12, 24, 36, 48, 60) the steps were repeated till the egg had reached the total time of 60 minutes. The changes in weight of the eggs were then added into a data table showing the weight of the chicken eggs in grams vs. the time in minutes. In a second data table the weight changes (g) vs. time (min.) between the eggs were taken and used the difference from each time and subtracted it from the initial

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Beets also known as Beta Vulgaris, contain a pigment known as betacyanin that gives the beets its deep rich red color, it is water soluble and is stored in the vacuoles of the beet roots and stems. Because the betacyanin is a water soluble pigment is can not easily cross the cell membranes.

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

In order to test this hypothesis and prediction, an experiment was conducted using a heterozygous F1 generation of Brassica Rapa seeds. The seeds were planted, pollinated, harvested (F2 generation) and germinated for observation. When leaves were visible, phenotypes (green vs. purple) were counted and recorded. The experiment took place over 13 weeks, spanning the full semester of General Biology Lab I. The sections that follow will detail the materials and methods used, the results of the investigation and an in-depth discussion of the outcomes.

Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer, which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites, some act as enzymes or carriers, while some are receptors. Lastly carbohydrate molecules of the membrane are relatively short-chain polysaccharides, which has multiple functions, for example, cell-cell recognition and acting as receptor sites for chemical signals.

In this experiment, my hypothesis was not supported. The hypothesis stated that acid rain would decrease the rate at which seeds germinate. The hypothesis is rejected due to the data which shows that the average sprout length of the control group is shorter than the experimental group. Although the experimental group grew taller and faster, the control group looked healthier. The control group’s sprouts were greener and stood up taller while the experimental group’s sprouts were a very milky-white green and leaned over some.

The plant material used in this experiment were marigolds. Planting the marigolds into six-pack cell containers, making the total plants used 54. Using three cell packs for every treatment mixture with third treatment being the controlled treatment, meaning that no material is added or taken from the solution. Treatment one was a mixture of miracle grow and perlite, what is perlite? Perlite is a lightweight particle that can hold up to four times its weight in water. The second treatment was a mixture of miracle grow with sand, leaving treatment three to be the controlled treatment which was just miracle grow.

The Purpose of this lab is to determine if predation or sexual selection have a greater effect on the population of guppies with a specific coloration. The lab will began with mostly bright guppies. Thus, if there are more predators than only the drabbest coloration guppies population would survive.

The hypothesis that black eye peas would have a higher respiration rate than lima beans because they are smaller was supported (Department of Biology, 2017) (Figure 1). Additionally, the hypothesis that the smaller mealworms would have a higher respiration rate than the larger meal worms because the small ones metabolize faster thus, requiring more oxygen was also supported (Department of Biology, 2017) (Figure 1). It was also expected that animals would have higher respiration rates than plants because plants will eventually use photosynthesis. This hypothesis was also supported.

Title: The Affects of Acidic Solutions on Lima Bean Plants Abstract: To determine the best Ph to grow bean plants at maximal growth we have conducted a controlled experiment. First grew twenty five pea plants in twenty five individual hydroponic pots, with 250 ml distilled water, until they grew into mature plants. Then divided those plants into five different sections, each section has five plants. Then tested five different liquids all having different Ph levels. These liquids are distilled water, tap water, lemon water, Tylenol water and sparkling water.

30 g of spinach leaf tissues were put into 50 ml of 0.5M sucrose buffer. The tissues are smashed and then strained with cheesecloth into the centrifuge tube. The product is centrifuge at low speed (200x g) to pellet large cell debris, and the supernatants are saved. The supernatants are centrifuge at high speed (1000x g) to pellet-out the chloroplasts. Chloroplasts are suspended in a 10% propylene glycol solution. The chloroplasts are placed in a boiling water bath for about 5 minutes. Seven labeled 14 ml tubes (1, 2R, 2W, 2G, 2B, 3, 4) containing 6.5 ml of 0.5M NaCl asay buffer. In tube #1 430 uls of boiled chloroplasts suspension was added and to the rest tubes 430 uls of un-boiled chloroplasts. Tube #3 was cover with foil, and tube #4 was
