In this lab, we soaked a gummy bear in water for twenty four hours to see the effects osmosis would have on it. When we got our gummy bear we would take its measurements and soak it in water. After twenty four hours we would take it out and record the measurements again and find the percent change. The question that we addressed in this lab was, what would happen if you soaked a gummy bear in water for twenty four hours? I hypothesized that after this time the gummy bear would increase in size.
The pipette was used to put the water into the behavior tray to create the wet environment in the second part of the lab. The water was used to create the wet environment. The procedure for the control part of the experiment starts by taking the Animal Behavior Tray and placing the filter paper in both sides of it. Next take the five Pill Bugs and place them into the behavior tray. Start the timer on the watch and observe the amount of Pill Bugs on each side of the behavior tray and how they are acting.
A lab report says they recovered nucleated epithelial cells from the mouth of the bottle and from the cap. But that’s all... They never tested those cells for DNA” (Koenig
Zimbardo states that in less than 5 days they had to end the experiment because the
The choosing of a specific egg is random but it was Humphrey’s fate to travel with the hand to the unknown. The hand of their god came down with great force and clamped Humphrey into the palm of his sandpapery hands. Once the god gripped Humphrey firmly, he yanked him into the sky. With this sacrifice made, Humphrey was taken to a warm “fire place” that made him so hot he felt like he was frying. The god picked up Humphrey and he was scared out of his mind.
Also, the pictures above show how the egg changed from being tight and solid to being flexible. The observations also say that the egg felt like a water balloon and was full of water inside. Overall, the egg greatly shrunk in size. Finally, when the egg was placed in corn syrup, it floated on the surface of the solution. This was because the egg floated in solutions hypertonic to its inside.
The Study of Diffusion and Osmosis Using Deshelled Eggs Maquita A. Dieufene Jessica Thelwell(Partner) 10/09/2014 1611 Evening Lab Introduction It is quite simple to overlook the roles diffusion and osmosis play in daily life. If one has ever spent too much time in the pool and watched as their fingers begin to turn prune-like, that is an example of osmosis. Osmosis is simply defined as the movement of a concentrated solvent through a semi permeable membrane to a more concentrated solvent.(Biology Corner) Relating to the earlier example of osmosis, your body acts as the more concentrated solvent for the water to penetrate. Diffusion is the exact opposite of osmosis.
The dogs salivated, so he proceeded to the next part of the experiment. He once again gave the dog the same food, but now before he put a plate in front of the dog, he rang a bell. After feeding the dog several times after the bell rang, the dogs started to salivate at the sound of the bell alone! Although the experiment was originally conducted to look deeper into the digestion
They had to stop the experiment by the sixth day because the guards started to abuse the prisoners and some of the prisoners were showing signs of emotional
In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.
So..? Scientist 1: I don’t know. (Scientist 1 sits down and rubs his head unsure about what he just saw) it kept crying, like it was
One scientist decides to take upon the task to figure out what is going on and dissects his own brain. Through the scientific method, the scientist discovers that because the atmospheric pressure rising that the air passing through their brain is slower. The slower the air passing through their brain, the slower their brains perform. This discovery led to the
In that view the experiment achieved its goal. The prisoners revolted, the guard violated the prisoners rights, and the experiment got so out of control that they had to stop after only 6 of the 14 days intended. The experiment was successful in many ways, it proved that the environment
1) It is important to have a constant supply of large numbers of sperm cells because it takes time for the sperm cells to mature about seventy-four days. So in this way of always having a lot of gametes in constant supply, allows there to be time for sperm cells to mature. It is a good advantage because not all sperm cells make it to the egg for fertilization. So in turn with more mature sperm in a large constant supply this will allow the sperm to have a greater ability to reach the egg for fertilization. 2) Males can sustain producing large amounts of sperm per second over a lifetime because the male sexual organs were made to produce a lot of sperm at all times.
Think of it like this, adding salt to the water makes it like an ocean which is easier to float and swim in than just normal/ distilled water. This is because salt makes water denser. When salt water gets denser, the easier it would be for objects to float on it. My hypothesis was correct. The water did go inside the egg, but the ones with least salt increased the most, unless the egg was the smallest and it had enough space to take in a lot of extra water.
