Introduction:
Euglenas are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglenas usually live in quiet ponds or puddles. (Biologycorner.com, 2016) Euglena is a interesting specie because they are combination of plant and animal. They can feed themselves through photosynthesis like a plant. Also, they move like animal. People have argued for many years about which Kingdom to put them. Most scientists put them in the protest Kingdom. So the question is that how does tempura affect Euglena growth. Personally, if the there is higher

Through standard curve, we know the relationship between absorbance and cell concentration is that the more absorbance the higher cell concentration. The data was measured by spectrophotometer which can be used to measure the concentration of a known chemical substance. The higher value of dada means that the higher concentration. At the same time, it means that the higher rate of growth. The table and graph directly reflect the relationship between temperature and speed of growth of Euglenas. The graph has shown a trend that first rise after falling. The sharpest change belong room temperature and the gentle change is that when Bioreactors in fridge. Therefore, we can draw a conclusion that when in room temperature (about 23) there is the fastest speed of growth. Excessive temperature will affect the growth of
We placed elodea plants into three different beakers and labelled them. Since, we are trying to find how temperature can affect the rate of production of carbon dioxide, we had to place them in different temperatures. So, we labelled the first beaker “Elodea heat” and placed it in a water bath that produced sufficient amount of heat. We labelled the second one “Elodea cool” which was placed in an ice bath filled with ice. The next one “Elodea RT” where the elodea was placed under normal room temperature without any interference. And we named the last one “No Elodea” where we placed no elodea in it and kept the beaker in a dark
In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm.
coli cells were grown at 37 degrees Celsius with calcium ions. These cells were then incubated in ice and placed into 4 polypropylene tubes. Each tube consisted of 25 microliters of E.coli cells. Two of the four were labeled with (+) while the other two were labeled (-). Positive was with samples that contained 100 pg/ microliter of pGLO, while negative was for the samples that did not. The 4 tubes were incubated in ice for 30 minutes, then heat shocked for 30 seconds at 42 degrees Celsius. The 4 tubes were then returned to the ice bath for 5 minutes. After the removal, .975 microliters of LB media was added to each tube at room temperature. The tubes were then shook at 225 RPM at 37 degrees Celsius for one hour. 300 microliters of cells were then extracted from the tubes and then placed in agar plates. The cells were spread across the plate and the incubated overnight at 37 degrees

...or the dark reaction and the brake for aerobic respiration. This allows for many ATPs to be produced, allowing the kinetosomes to anchor the flagellum of Mr. Euglena through the cell membrane. This anchor enables the flagellum to function, which will move Mr. Euglena to a less crowded area in order to live.
Lillia Davidson, my grandma was born mid war, 1940 to Shirley and Ed Kittle. Lillia, her 2 siblings and their parents lived in a small apartment in Glenbrook, Connecticut from 1940 to 1943, her family moved to the Vermont countryside when she was four. Her parents were not rich Shirley was a seamstress and Ed did was was called a civilian job meaning he did not get paid, he would keep an eye out for suspicious plains. Though her dad was not in the war she felt proud that he was helping with the war. Ed’s job of being a spotter become very important after the bombing of Pearl Harbor in 1941. My grandma has no memory of Pearl Harbor because she was so young. Being so young sheltered her from a lot of what was going on at that time.
Albana Gallari is an Albanian Immigrant who moved to the United States on February 16, 1997. Gallari was born in communist Albania on March 4, 1974. Gallari lived under the reign of Communist Dictator Enver Hoxha throughout her early life. Gallari grew up poor with little to eat besides bread and cheese and had almost no material possessions besides 3 pairs of clothes along with 3 tattered dolls. Throughout her early life her mother took care of her alongside her job of working in a government factory and her father was a livestock veterinarian. Gallari faintly remembers going to her friend's house on Sundays to watch cartoons due to her family being too poor to afford a television. After the communist regime fell in 1992, Gallari became a

Lycaons are world known for being, "werewolves." Not many people have heard the myths that came from Greek mythology. The Mystery behind this is fascinating and unique compared to what Hollywood has made it be. The areas that need to be focused on is the Myths, His only son, and the downfall of his ruling. This is a Greek Mythological king that more people should understand.
The test tubes were labeled. Each of the Erlenmeyer flasks were filed with approximately 225 mL of regular tap water. The two of the aquatic plant Elodea densa was obtained. Each plant was submerged in a solution of 0.5% solution of sodium bicarbonate in a test tube, and approximately 0.5 cm was cut off the stem. A rubber stopper, containing an attached pipette, and syringe and need was placed over each test tube. Then, the stopper was gently pushed into each test tube, making sure no air bubbles were present. Each of the Erlenmeyer flasks containing the test tubes was then placed in front of a lamp. After being calibrated in front of the lamp for 10 minutes, the reading was taken for 40 minutes. Finally the lamp was turned off. Following the experiment, the results were entered into an Excel spreadsheet. Using the online t-test software “graphpad”, an unpaired t-test was generated. In this investigation the light intensity, and temperature, and aquatic plant (Elodea densa) were constant, and thus where the control variables. (Rush,
Aim of the research: The aim of this investigation is to determine what kind of effect will the increasing temperature have on the plasma membrane of a beetroot cell.
The cultures were maintained at 25±20C under 16 hr illumination of 4000 lux intensity. The results are presented in Table 1, it can be seen from the data that pH of the medium had significant effect not only on regeneration frequency but also on number of shoots developed in each culture. Maximum 62.5±4.7 percent cultures in CoS 98259 and 67.3±4.9 percent in CoS 767 developed shoots at pH 6.0 while regeneration frequency was the lowest at pH 5.6. An increase in pH form 6.0 to 6.2 and 6.4 reduced the frequency of shoot regeneration from the callus (Table
Increases in temperature can decrease the efficiency of photosynthesis; however the extent of this impact may be determine on the species' dependency on light.
Diatoms have a unique characteristic. They live in an outer cell wall, or a frustrule made of silica. This frustrule is not just for the physical appearance, it provides protection and even structure. On the cell wall, there are spikes, spines and pores which allow diatoms to be classified into different classes, the centric (Centrobacillariophyceae) and the pennate (...
