Photography had so much more of an influence on the Impressionist movement than just photography in its own right. Photography influenced artists in their paintings‚ in their pastel works‚ in their sculpture and in seeing the world around them in a different way. Modern artists were influenced by the invention of the camera because it gave them a cropped composition and showed the tonal effects of light and dark in much finer detail than they could interpret with the naked eye. This technology made

neck‚ the bird begins to tip over into the beaker of water - The whole head of the bird is wet because it’s made of spongy absorbent type particles that make it able to absorb some of the water Brainstorm - The beaker of water effects the bird’s movement - Tilted head of bird causes red substance to go back down and the head is able to come back up - Evaporation is what is happening through the head of the bird and the neck Interaction - When moving the beaker away the bird stops moving - The feather

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black

In the Calvin cycle‚ carbon atoms from CO2 are fixed and used to build three-carbon sugars. This process is fueled by‚ and dependent on‚ ATP and NADPH from the light reactions. Unlike the light reactions‚ which take place in the thylakoid membrane‚ the reactions of the Calvin cycle take place in the stroma. In the Calvin cycle‚ getting pulled into the cells using RUBISCO to facilitate the process incorporated gaseous CO2 molecules. RUBISCO acts much like a sponge with a great absorptive power to

question was “How does exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up

breathing rate will increase during exercise. It was hypothesised that if the amount of exercise (independent variable) increases‚ then the individual’s heart rate (bpm) and breathing rate (breaths-pm) (dependant variables) will increase when the environment in which the exercise is completed and a consistent and appropriate method of measurement for the dependant variables are kept constant. It was hypothesised that if physical exercise was increased‚ an individual’s heart and breathing rate would increase

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

Enzymes are biological catalysts that speed up the rate of chemical reactions by lowering the reactants’ activation energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue

evaporates‚ it lowers the temperature of the substances around them‚ because evaporation is an endothermic process. In the graph‚ each substance has a different curve. Some lowered the temperature much more than others. This is because different substances require differing amounts of energy to evaporate. To test this‚ the temperature change from the evaporation of 4 different alcohols was measured and compared‚ along with cyclohexane. Methanol had the largest change in temperature‚ 18.9 ºC.
