Potato Puree Lab Report
The purpose of this experiment was to determine which habitat (dependent variable) the pill bugs preferred water or potato puree. The 5mL of water (control) and 5 mL of potato puree (independent variable) was placed into two small beakers. Next, the two filter papers were placed into two petri dishes. The filter papers were moistened by using a pipette with 10 drops of water and potato puree, respectively. It is important to remember to make sure there is no excess water/potato puree. Too much water/potato puree could drown the pill bugs. The lightly wet filter papers were placed into the choice chambers. Gently, place all ten pill bugs into the middle of the choice chambers using the tweezers. The movements of the pill bugs in the choice chambers

Ladybugs Research Paper
1207 Words | 5 PagesFor hundreds of years, ladybugs have been greatly appreciated by farmers. Ladybugs will feed on the crop-damaging insects such as caterpillars, and, essentially, save the crops. Unfortunately, many of the farmers that work in colder climates cannot use ladybugs to keep their crops alive because the insects live only in warmer climates. Thankfully for them, there are some organic pesticides that keep the ladybugs alive, even in cold climates! These pesticides allow ladybugs to eat all of the insects that farmers don’t enjoy having around.
Chemical Digestion Lab Report
297 Words | 2 PagesThe process of chemical digestion in the breaking down of food with enzymes so that they can become molecules such as nutrients, salts and water , so that way they are easily absorbed and utilized. The process of absorption involves moving such molecules through the GI epithelium and into the blood or lipids. Ingested food is initially broken down mechanically by your mouth into pieces that are easier to swallow, and then broken down again into even smaller pieces so that in can continue its journey through the stomach and into the small intestine. These food particles are primarily made or major nutrients and minor nutrients. The major nutrients such as carbohydrates, protein and lipids must be broken down further enzymatically in order

Tetrahymena are often used in experiments because they are easy to culture and have similar life processes as multicellular organisms. Tetrahymena is covered with short hair-like projections or cilia, that sweep food particles into its oral groove.
Oviposition Of Callosobruchus Maculatus Lab Report
159 Words | 1 PagesThe purpose of the present experiment was to assess the oviposition of Callosobruchus maculatus by manipulating the size of the Lima bean in context of the oviposition and fertilization success. By placing the same amount of Callosobruchus maculatus and lima beans of varying sizes in petri dish, it allowed the beetles to choose and oviposit their eggs over a two-week span. The small lima beans were separated from the large lima beans into equal amounts contained in two petri dishes with the same number and ratio of male to female Callosobruchus maculatus. Based on the results from the t-test (t[38]= 3.0955) there is a statistical significance between the size of the lima beans and the oviposition/fertilization success rate. Based on these findings
Lab Report On Fermentation
1432 Words | 6 PagesJoshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.

Kessler et al. tested in a controlled laboratory where they looked at three pesticides (clothianidin, imidacloprid and thiamethoxam). Feeders contained neonicotinoid-treated sugar water or untreated solution. Their results showed that the worker bees did not avoid the neonicotinoid-treated sugar water,
Pros And Cons Of Infection And Predation
190 Words | 1 PagesBiological control usually focuses on 1 natural enemy that prove efficiency in terms of pest control in laboratory condition. One criteria we have to take into account is the specificity of viruses as well as any other control agents. In the fields, pest control efficiency can be limited, first of all, because of environmental conditions that affect control agents and decrease their survival time and also the number of hosts infected. Then, in the field, pests are the prey of different predator communities and so the control agent compete with other natural enemies for the same host.
Potato Osmosis Lab Report
1078 Words | 5 PagesBiology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).

Sphecoid Wasps Essay
3949 Words | 16 PagesIntroduction Among all the animals living on earth, insects are the most diverse. They are found in all habitats such as deserts, forests, swamps and even the pools of crude petroleum (Imms, 1964).The number of insects exceeds all other animals and this due to the undeniable fact that they are able to adapt themselves to any kind of environment. The evolution of flight in insect is regarded as the significant breakthrough in the history of Earth. They were the first to dominate the air even before other terrestrial animals and also the time taken for diversification go beyond other organisms which all together lead to their dominance across the planet. Most of the insects are considered important to human beings and the environment as they
