How can the measuring rate of photosynthesis be accurately determined in a controlled experiment?
The rate of photosynthesis can be accurately determined in a controlled experiment by measuring the amount of oxygen produced by the plant over a specific time period. This can be done using a device called a gas exchange analyzer, which can track the changes in oxygen levels in a closed system where only the plant is present. By monitoring the increase in oxygen concentration, scientists can calculate the rate of photosynthesis occurring in the plant.

Why is hydrilla stem cut underwater in photosynthesis experiment?
Hydrilla stems are cut underwater in photosynthesis experiments to prevent air from entering the stem and disrupting the oxygen levels in the water. By cutting the stems underwater, scientists can maintain a controlled environment for studying how plants release oxygen during photosynthesis. This method ensures that the oxygen measured in the experiment accurately reflects the photosynthetic activity of the plant.
Engelmann's experiment determined which wavelengths of light are most effective at causing photosynthesis In other words Engelmann measured?
Engelmann's experiment measured the rate of oxygen production by algae exposed to different wavelengths of light to determine which wavelengths are most effective at driving photosynthesis. He found that red and blue light were the most effective, with peaks in their absorption spectra correlating with peak photosynthetic activity.
What is the procedure that tests a hypothesis by collecting information under controlled conditions?
The procedure that tests a hypothesis by collecting information under controlled conditions is called an experiment. In an experiment, researchers manipulate one or more variables to observe the effects on the outcomes of interest. This controlled setting allows researchers to make conclusions about the relationships between variables.
What is the correct definition for controlled experiment?
A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.
The one factor that differs in a controlled experiment?
In a controlled experiment, the one factor that differs is the independent variable. This is the variable that is deliberately changed or manipulated by the researcher in order to observe its effect on the dependent variable. The goal of a controlled experiment is to isolate the impact of the independent variable on the dependent variable while holding all other variables constant.
What is a fingerprint patterns controlled variable?
A fingerprint pattern is not a controlled variable in a scientific experiment. Controlled variables are factors that are intentionally kept constant to ensure that the effects of the independent variable can be accurately measured. Fingerprint patterns are unique to individuals and cannot be controlled or manipulated in a controlled experiment.
When is controlled experiment?
controlled experiment
Why is an experiment called a controlled study?
An experiment is called a controlled study because it involves manipulating variables under controlled conditions to isolate the effects of those variables on the outcome or results. By controlling other factors that could influence the results, researchers can more accurately determine the impact of the variables they are studying.
What is make an experiment a controlled experament?
A controlled experiment is one in which all variables except the one being tested are kept constant or controlled. This allows researchers to accurately measure the impact of the variable being tested on the outcome of the experiment. By controlling for other factors, researchers can isolate the effects of the specific variable they are interested in studying.
In a research study if one variable is changed to see how it affects behavior the study is most likely a?
experiment

How much amylase enzyme should be used in the experiment?
The amount of amylase enzyme needed for the experiment should be determined based on the specific protocol or instructions provided. It is important to follow the guidelines accurately to ensure the success of the experiment.
Why is a controlled experiment better than a non controlled experiment?
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
What best describes a property controlled experiment?
A property controlled experiment is a scientific experiment where all variables are kept constant except for the property being tested. This allows researchers to accurately measure the impact of that specific property on the outcomes of the experiment. By controlling all other variables, researchers can confidently attribute changes in the outcome solely to the property being studied.
What type of scientific investigation should Tyler conduct in order to accurately answer his question through direct observations?
Tyler should perform a controlled experiment
What an investigation that is controlled?
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
What is the difference between a controlled experiment and a controlled group?
a controlled group is like an idea but an experiment that is controlled cannot be changed.
