The effect of extreme heat on catalase function what are you looking for in your observations when you are looking for evidence of a reaction? does the plant tissue that we tested contain catalase? does the animal tissue that was tested contain catalase?

When looking for observations for evidence of a reaction, you are looking for bubbles which will be the evidence of chemical reaction. Oxygen gas is formed only if the products are formed and the reaction happens. We see gas as bubbles when the gas is formed in a liquid. The plant here which we are testing is a potato and found that it contains catalase because a lot of bubbles are present and created a foam which rises near the top of the test tube. 

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

i won't lie i don't know so go online and ask google thats what i do
