Investigating The Rate Of The Red Water - 1742 Words

The aim of this experiment is to observe and record the rate of the blue water in the dialysis tube diffusing into the beaker containing different concentrations of salt over 20 minutes to see what effect the concentrations of salt has on the rate of diffusion. The hypothesized of this experiment is that the blue water in dialysis tube 3 will have a faster rate of blue dye diffusing into the salt water in beaker 3. Beaker 1 will have the slowest rate of blue dye diffusing from the dialysis tube into the salt water and beaker 2 will result in a colour in-between beaker 1 and 3. This is because the concentration of salt in the beaker is higher than the water in the dialysis tubes so the salt water will go into the dialysis tube while the blue water in the dialysis tube will diffusion into the beaker. This experiment was performed by measuring out the same amount of water into each of the 3 beakers and adding different amounts of salt to each one to change the concentration. 3 dialysis tubes containing water and 3 drops of blue dye were tied at one end, then tied at the other using cotton thread before placing them one each into the different concentrated beaker cotton tied end facing down. After 20 minutes the results were observed and recorded into the results table. The finishing results were unexpected and not accurate due to the systematic and random errors, rejecting the hypothesis.

Light dependent reaction mostly takes place in thylakoid membranes of the chloroplasts. When the sun hits the chloroplast the light and water comes into the thylakoids then oxygen and ATP and NADPH produced.( Shows on Diagram 2) Figure 4: The diagram describes how does light-dependent andRead MoreHcs 320 Communication and Crisis Essay1261 Words   |  6 Pageswith a problem that will require communication between several internal and external avenues to help resolve the water contamination in the Eugene-Springfield area.

We are researching to increase the efficiency of cultivation. In order to reach this goal, we are investigating the relationship between natural auxin, Indole Acetic Acid (IAA) and synthetic auxin, Naphthalene Acetic Acid (NAA).

Dyes dissolve in water, lakes are water insoluble. As a water insoluble form of the dye, lakes are more stable than dyes, and better for coloring products containing fats and oils.

Five of the nine certified colors can be found in MM candies. â€Å"In the U.S. there are seven FDA –approved, mostly petroleum-derived, food dyes currently in use: blue 1, blue 2, green 3, red 40, red 3, yellow 5, and yellow 6.

The merozoites within the red blood cells will form a ring-like structure and then a trophozoite (Malaria â€⠀œ Plasmodium, 2013). These trophozoites repeat the process of asexual multiplication and produce more daughter merozoites. This cycle repeats itself; the merozoites invade the red blood cells, multiply or replicate and then rupture the cell.

These hypotheses will be supported by investigating the physiological adaptations of the Plesiosaurs biological analogues, and the prospect of similar adaptations in the former will be speculated upon. Reptiles have a low metabolic rate: they consume energy, and therefore oxygen, slowly. According to Robinson (1975), Plesiosauroids were enduring swimmers with lower flipper aspect ratiosRead MoreThe Effect Of Osmosis On The Rate Of Osmosis1566 Words   |  7 Pagesreasoning behind this experiment is the examine whether the rate of osmosis is changed due to a change in temperature. It was hypothesized that the rate of osmosis will increase as the temperature of the sucrose is increased. The rate of osmosis was tested by using the different jars full of different temperate water and testing how high the water rose on an osmometer over a span of 20 minutes. An osmometer is a tool used to measure rates of osmosis. The different temperatures tested on a sucroseRead MoreGeography Unit 21672 Words   |  7 Pagesbe focusing on rivers and I have chosen a hypothesis to prove that erosion is making an impact on the Loughton Brook Rivers.

Toxins include pore-forming toxins, which destroy healthy cells by creating holes in their membranes. Nanosponges are biocompatible polymers of nanoparticles, which are coated with a membrane similar to a red blood cell’s to travel undetected through the body. This synthetic membrane attracts toxins and inhibits them from damaging cell membranes. Upon reaching the liver, the toxin and the nanosponge are eliminated from the body. Unlike other highly specific
