we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred

proteins to see if they denature at the same temperature. A protein is a molecule containing amino acids created in ribosomes that have many functions‚ including being an enzyme and transporter‚ structuring‚ translating genetic information‚ and serving as a channel for charged molecules to pass through the cell membrane. As a molecule‚ a protein is shaped like a coil (Food Science Basics 2014). Denaturation is when a protein’s shape changes due to the effect of external stress which causes the protein

spectrum of sunlight yields the highest temperature? My hypothesis is that the blue/violet part will have the highest temperature. The blue/violet part has the highest frequency out of all the colors on the visible light spectrum and it also has the highest amount of energy. Therefore‚ I hypothesize that it will have to the highest temperature as well. After conducting the experiment‚ I noticed that during the duration of five minutes‚ the temperatures of all four thermometers increased. The

Aim: Investigate the effect of different temperatures and chemicals including various pH levels‚ alcohol and detergent on the cell membrane structure as well as function. Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane. Materials: Part A • Bunsen Burner‚ Tripod and a Wire Gauze • 250mL Beaker • A 100° thermometer • Matches • 10mL measuring cylinder • Sticky labels and a Pen

The goal of this experiment was to explore how temperature would influence the rate of cellular respiration of beans. It was hypothesized that as the temperature of the beans increased‚ the rate of cellular respiration would increase as well. In this experiment‚ the independent variable was the temperature‚ which gradually increased as time went by‚ and the dependent variable was the rate of cellular respiration‚ which was shown by the change in the amount of CO2 and O2 in the container. During the

Practicing a sport is much more than the pure act of pushing your body through exhaustion or using your skills to reach your goals. There are many effects that show after you get involved in a sport. I am going to discuss some effects in this paper. The first major effect of practicing a sport is that you will develop physical abilities. Your body will be in better shape and you will be able to do things that you couldn’t physically do before. For example your speed‚ strength‚ stamina‚ lung capacity

pollution can cause decreases in wildlife animal population‚ hurt the ecosystem‚ and threaten human health. But there are negative effects that are hard to ignore. Toxic pollution has been linked to cases of marine animals getting cancer‚ lesions‚ genetic and developmental defects‚ reproductive failures‚ sex changes‚ and death. Keep in mind that these are only the effects that humans are aware of. There very well could be other consequences that we just don’t know

It is known that Melatonin causes many adverse effects such as headaches‚ dizziness and nausea Many research has been done on the correlation between age and the effect of Melatonin. In some countries‚ Melatonin can be bought without prescription and therefore it is possible for children to intake in large doses. However‚ (Arendt) has shown that it may affect
