control, and determining if the fertilizer has accurately distributed chemicals needed for healthy plant growth. There are three main Chemicals needed for strong, healthy plants; nitrogen, phosphorus, and potassium. Nitrogen is important for the plant’s growth, and for the growth of the plant’s leaves, while potassium and phosphorus help the roots grow stronger, and healthier, along with helping the plant produce flowers. When looking at the box of fertilizer you will find a set of numbers, such as

Abstract: The purpose of this lab is to measure the rate of photosynthesis in isolated chloroplasts. The lab begins with adding solutions to multiple cuvettes, then adding either boiled chloroplasts, not boiled chloroplasts or no chloroplasts. After approximately 5 minute timed sessions in light, tubes are placed in spectrophotometer one at a time and the transmittance percentage is recorded for each test. Boiled chloroplasts are denatured, so photosynthesis cannot occur. Solutions in test tubes

The findings in this experiment did not match our original hypothesis. In fact, it was our belief that the pill bugs would spend most of the time in the leafy mixture making it their most preferred environment. The experiment led to the disprovement of our hypothesis. From the very start of the first part of our experiment, we realized that the pill bugs were very fond of the soil substance, much more than the leafy mixture. Based upon the time that the pill bugs spent in the soil during the

Today Madagascar has lost about 90% of its forest due to logging, burning, and other commercial practices (5).These Madagascan animals are becoming extinct because of deforestation, being hunted for food, and being sold in illegal pet trade market. The animals also lose their habitats because they live in poor areas that log for money. Some animals became extinct when carnivorous fish were introduced to the ecosystem. Deforestation has caused the loss of the Fossa’s hunting territory. This has also

The Eastern Cottontail is a species of rabbit. It has large hind legs which make the Eastern Cottontail look more like a hare, and there is a difference. The difference between a rabbit and a hare is that a rabbit's fur is always the same color whether it's Spring, Summer, Fall, or Winter. Another difference between the two is that hares have longer hind legs for leaping long distances. The Symmetry of a rabbit has bilateral symmetry meaning that the rabbits symmetry is straight down the middle and

Have you heard the term cannabis? Of course, you must have heard cannabis as the source of drugs and weed. The cannabis plant is the hub for the production of drugs. Cannabis plant is first steamed and further distillation of the flowers and upper leaves gives us cannabis essential oil. Cannabis and hemp are the plants that are used as herbs in various parts of the world. But the term cannabis oil is very vital to all mankind. Cannabis essential oil is very volatile oil and little amounts of oil

Slugs preference is cool weather such as rain and fog as they do not have the outer shell to protect them. The dry weather or heat may dry them out. When the weather is warm and dry the slug will attempt to find shelter in a cool and dark place, usually damp. However if there is a long dry spell then the slug will encase themselves in a papery cocoon-like structure and attach themselves to a wall or tree and wait until the weather is cooler. Due to slugs bodies being comprised of mainly water and

We measured the biodiversity of plants in different places in Costa Rica. We did this in Costa Rica because Costa Rica is a country that puts a lot of emphasis on preserving the environment. We took a string that was approximately 1.5 meters long, formed it into a circle, and counted the number of species of plants and how many of each species there were within our circle. We then used the Simpson’s Index of Diversity to calculate the diversity. We did this at four sites including Monteverde (Site

Photosynthesis Design Lab: Aim: To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Background: Leaf disks float, naturally. When the air spaces are filled with a solution the overall mass of the leaf disks increase and they then sink. The solution used includes a small amount of Sodium bicarbonate (NaHCO3). This Bicarbonate ion acts as a carbon source for photosynthesis. As photosynthesis continues, oxygen is then released into the inside of the leaf disk which
