Describe how to carry out simple controlled experiments to illustrate how enzyme activity can be affected by changes in temperature?
· Add 2cm^3 of amylase to a test tube
· Add 2cm^3 of starch
· Add a few drops of iodine
· Place test tube into water bath at a certain temperature
· Observe colour changes every 2 minutes
· Record time taken for iodine to change back to yellow
· Repeat the experiment at different temperatures

What is used to describe a trait that is controlled by many genes?
A genetic trait.
Which term means finding ways to describe and explain the natural world through observations and experiments?
The term that describes finding ways to describe and explain the natural world through observations and experiments is "scientific inquiry." This process involves formulating hypotheses, conducting experiments, and analyzing data to understand natural phenomena. It is fundamental to the scientific method, which emphasizes empirical evidence and reproducibility.

What is the difference between systematic observations and experiments?
Systematic observations involve carefully watching and recording behaviors or events in their natural settings without manipulation, allowing researchers to gather data on real-world phenomena. In contrast, experiments involve manipulating one or more variables to determine their effects on a dependent variable, often conducted in controlled environments. While systematic observations aim to describe and understand phenomena as they occur, experiments focus on establishing causal relationships through controlled testing.
Should you describe simple analog experiments in your scientific report?
If the experiments were worth doing, then they are worth being reported.
When might you need to use a thermometer in the lab Describe a situation?
You might need to use a thermometer in the lab when conducting experiments that involve temperature-sensitive reactions, such as a chemical reaction that releases or absorbs heat. For example, if you're synthesizing a compound that requires maintaining a specific temperature range to ensure proper reaction rates, you'll need to monitor the temperature accurately. Additionally, when performing experiments in biological studies, like culturing microorganisms, a thermometer is essential to maintain optimal growth temperatures.
