We used Brassica rapa, a fast plant the rapidly reproduces, in an experiment that we performed a monohybrid cross and a dihybrid cross. We hypothesized that in the monohybrid cross, the F2 generation of Brassica rapa will follow Mendelian inheritance patterns and show a phenotypic ratio of 3 anthocyanin positive to 1 anthocyanin negative. If the F2 generation follows Mendelian inheritance patterns, then out of 1105 plants, 828.75 will be anthocyanin positive and 276.25 will be anthocyanin negative. For the dihybrid cross we hypothesized that the F2 generation of Brassica rapa will follow Mendelian inheritance patterns and show a phenotypic ratio of 9 Anthocyanin positive dark green to 3 anthocyanin positive yellowish green to 3 anthocyanin
The gametophytes used in this experiment are of C-ferns. They tend to mature and produce spores at temperature of 28oC and conditions of high humidity. The spores that germinate first are hermaphrodites. Hermaphrodites tend to produce a pheromone called antheridiogen. It is this pheromone that causes later germinating spores to become male.

Above in table 4.1 the results are shown. Test tube 2 was the only tube that had a change in color. The reason that test tube 2 was the only one that changed in color was because a reaction that was produced by catechol oxidase. Tube 2 was the only tube that had potato extract and catechol this is why the reaction occurred. The potato extract and catechol was not present at the same time in the other tubes and that is the reason they had no change.

Sordaria fimicola is a species of microscopic fungus that is an Ascomycete and are used to test for genetic variation in the lab setting (Sordaria fimicola: A Fungus used in Genetics, Volk). These organisms are what are called model organisms, or species that has been widely studied usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages (Sordaria fimicola, Volk). S. fimicola, because it is in the Ascomycota phylum, have a distinguishing reproductive structure called the ascus, which is surrounded by the perithecium. This cylindrical sac-like structure houses 8 haploid spores; created through meiosis to produce 4 haploid spores and then mitosis to make 8 (Lab Manual, pg. 59-68). Based on the genotype they will vary in order and color. There are 3 different ratios that can arise from the 8 ascospores: 4:4, 2:2:2:2, and 2:4:2 (black/wild type and tan coloration). The 4:4 ratio suggests that no crossing over had occurred because there is no difference in order of the color parents that were mated. The two other ratios suggest genetic recombination, or crossing over, because of the
The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself.
Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag.
As the reaction was taking place, the water in the measuring cylinder was being displaced – indicating that the calcium carbonate (in the form of marble chips) was displacing the hydrogen in the hydrochloric acid.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.
Osmoregulation is an example of an organism maintaining homeostasis. More specifically, osmoregulation involves an animal regulating osmotic pressure, or its fluid content. Brine shrimp, Artemia, use osmoregulation to regulate the saline levels of fluid within their body. Because brine shrimps live in seawater, an environment with a high saline concentration, they must actively excrete excess salt. Brine Shrimps use metepipodites as the location of the ion pump which secretes sodium. This is an active transport of ions because it is moving against the gradient, a higher salt content outside the body. The two following studies describe the environmental conditions ideal for brine shrimp and the possible genetic explanation for the osmoregulation of brine shrimp, respectively.
c solution and sucked up some of the water in the cells. When we observed the cheek cells we found they were very different from the plant cells. The nucleus was in the middle of the cheek cells and there were a few cell organelles. The Planaria cell was all red and had lines running down it.
Introduction Within the cells of a beetroot plant, a pigment is held within the vacuole of a beetroot cell, this pigment gives the beetroot its red/purple colour. If a cell is damaged or ruptured in a beetroot and the cell surface membrane ruptures, the pigment 'drains' from the cells like a dye. It is this distinction that can be employed to test which conditions may affect the integrity of the cell surface membrane. The pigments are actually betalain pigments, named after the red beetroot (beta vulgaris) it breaks down at about 60ºC. They replace anthocyanins in plants.
