What else can I help you with?
A student was performing an experiment about the rate of photosynthesis in a certain type of algae when it is exposed to different intensities of light What is the independent variable?
The independent variable in the experiment is the intensity of light exposure. This is the factor that the student is manipulating to observe how it affects the rate of photosynthesis in the algae. By changing the light intensity, the student can measure the resulting changes in the photosynthetic rate.
What are the two other variable that affect photosynthesis?
Two other variables that affect photosynthesis are temperature and carbon dioxide levels. Photosynthesis rates increase with higher temperatures up to a certain point, beyond which they decrease. Carbon dioxide levels also influence photosynthesis, as higher concentrations can boost the rate of photosynthesis up to a certain level.
Can cell repiration occur in organism at a temp above 65 deg centigrade - give reason?
The rate of any reaction depends on the active masses of the reactants, the pH and the temperature. This applies to the biological reactions involving enzymes like cellular respiration The enzymes in general get more and more active as the temperature increases. This would be true till the temperature reaches up to 45 degree Celsius (in general for humans). Above which some enzymes denature and their activity completely drops off. This temperature is variable and is dependent on the enzyme. (A few enzymes are active even at high temperatures). But at 65 degree Celsius most of the intracellular enzymes are denatured. So as the temperature increases, the cellular respiration increases up to a certain point and then there is a sharp decline so at or after 65 degree Celsius cellular respiration is virtually impossible.
What are the differences between independent and dependent variables?
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
What is an independent variable in science?
An independant variable is the variable in science that you'll be changing throughout the experiment. Like if you were experimenting on plants, the independant variable is how many plants you'll be taking out and putting back in. For example, you take out one of the bad plants and include three more.
What is the independent variable of the Cellular Respiration?
The independent variable in cellular respiration experiments is usually the substance that is being manipulated or changed, such as the type of substrate or the presence of inhibitors. It is what researchers control and manipulate to observe its effect on cellular respiration rates.
What is the variable that changes as a result of the scientist changing a variable?
It is a control variable.
The independent variable?
The independent variable is the one that is changing
What is the name of the variable that is changed by another variable changing?
The variable that is changed by another variable changing is often referred to as the dependent variable. It is the outcome or response that is being studied in an experiment or research study.
What is the variable that changes as a result of a scientist changing a variable?
The variable that changes as a result of a scientist changing another variable is called the dependent variable. It is the variable being observed or measured in an experiment to see how it responds to the changes made to the independent variable.
Identify the independent variable?
The independent variable is the one that is changing
Is The independent variable is the variable that is changed in an experiment?
the independant variable is what you are changing in each test..

Why is oxygen the dependent variable in photosynthesis?
Oxygen is the dependent variable in photosynthesis because its production is directly influenced by the independent variable, which is typically the light intensity, CO2 concentration, or temperature. The amount of oxygen produced by the plant depends on the conditions provided for photosynthesis, making it the variable that is being measured or observed in the experiment.
The portion of aerobic respiration that produces the most ATP per molecule of glucose is?
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
What is the variable that scientist observes changing while conducting an experiment?
The variable that scientists observe changing while conducting an experiment is called the independent variable. This is the variable that is intentionally manipulated or changed by the scientist to observe its effect on another variable, known as the dependent variable.
What is Constantly Variable?
Always changing
