4.2 Closure Activity

How does energy transform during cellular respiration?

• Energy is converted from glucose to ATP.

• Energy is lost as heat.

• Energy is stored as fat.

• Energy is converted to light.

The difference between independent and dependent variables is that:

• independent variables are manipulated to observe the effect on dependent variables, which are measured

• dependent variables are manipulated to observe the effect on independent variables, which are measured

• both variables are manipulated to observe their effects on each other

• neither variable is manipulated or measured

The purpose of a control group in an experiment is to:

• provide a standard for comparison

• introduce new variables

• ensure the experiment is biased

• increase the sample size

What are the by products of cellular respiration in animals?

• CO2 only

• H2O only

• Glucose

• CO2, H2O, and ATP

The purpose of creating graphs and charts in analyzing experimental results is to:

• visualize data for easier interpretation

• complicate the data analysis process

• eliminate the need for data collection

• replace statistical analysis

Identifying patterns helps in drawing conclusions from experimental data by:

• providing a structured approach to analyze data

• eliminating the need for further experimentation

• ensuring data accuracy

• guaranteeing successful outcomes

Recognizing experimental errors is crucial in scientific research because:

• it helps in validating the results.

• it complicates the research process.

• it is not important.

• it is only necessary for theoretical research.

The scientific method is applied in cellular respiration to:

• observe and measure the process of energy conversion in cells

• create new cells through genetic engineering

• develop new theories about plant growth

• study the effects of temperature on photosynthesis

One is testing fertilizers on tomato plants. In plant A, there is no fertilizer. In plant B, you are using one brand of fertilizer. In plant C, you are using a different fertilizer. Every week, the plants are measured to see which plant has grown the tallest.

Which is the control?

• The plant

• The Fertilizer

• The height of each plant

• The unfertilized plant
