I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

The average temperature in Santiago is 14.4°C with January being the warmest at an average temperature of 21°C and June and July being the coolest months‚ both with an average temperature of 8°C. For what is considered to be fall and winter in the northern hemisphere‚ is spring and summer in the southern hemisphere‚ therefore that is when Santiago’s climate is at its peak. It can be noticed that from January to June and July‚ the temperature starts to change at a not so slow

Spilled Salt By: Barbara Neely Something I liked about this story was that it had a realistic plot. It’s completely possible for a mother to have her son go to jail and come back unexpected. This actually happened to someone I knew‚ they were in jail for raping a girl‚ when they really didn’t and his mom had a hard time dealing with him being back from jail when really she just wanted him to leave her life completely. Something I didn’t like about the story was the character of the mom‚ she seemed

The problem that we are solving is “How does the temperature outside affect the speed and heart rate of the runner?” We chose this to investigate “How does the temperature outside affect the speed and heart rate of the runner?” because we both play sports that require lots of running (Track and Field and Soccer.) Therefore‚ when running track outdoors the weather at the beginning of the meet may be colder‚ than the end when it’s most likely hotter. As well as a soccer tournament‚ you may play a tournament

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

Salt is modern book written about the history of salt and its effect on the events of the past. The book maintains a semi-chronological flow to it. It is nonfiction and there are no characters. Salt has had an effect on the past that is often overlooked‚ but not by the author of Salt‚ Mark Kurlansky. Salt takes you through the history of the only edible rock. It begins talking about the sexuality of salt as a hook‚ then begins talking about the nutrition of salt. The rest of the book is about different

Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then‚ mixing teaspoons of salt in water one at a time‚ until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is‚ salt does infact change water’s density‚ and if the egg floats it’s proof of density change in the water‚ because it must be less dense than the
