Command Terms in IB Biology

Which command term involves giving a sequence of names or brief answers with no elaboration?

• List

• Define

• Draw

• Measure

Answer explanation

The command term 'List' requires providing a sequence of names or brief answers without any further explanation, making it the correct choice for the question.

What is the purpose of the command term "Describe"?

• To give a detailed account

• To find an approximate value

• To distinguish between items

• To add brief notes to a diagram

Answer explanation

The command term "Describe" requires providing a detailed account of a subject, including its characteristics and features, rather than approximating values, distinguishing items, or adding notes to diagrams.

Which command term involves finding an approximate value for an unknown quantity?

• Estimate

• Identify

• State

• Describe

Answer explanation

The command term 'Estimate' specifically refers to finding an approximate value for an unknown quantity, making it the correct choice. Other terms like 'Identify', 'State', and 'Describe' do not imply approximation.

What is the purpose of the command term "Outline"?

• Give a brief account or summary

• Find an approximate value

• Distinguish between items

• Add brief notes to a diagram

Answer explanation

The command term "Outline" requires you to give a brief account or summary of a topic, highlighting key points without going into extensive detail. This distinguishes it from other options like finding values or adding notes.

Which command term involves giving a judgment based on a given statement or result of a calculation?

• Construct

• Comment

• Compare and Contrast

• Deduce

Answer explanation

The command term 'Comment' requires providing a judgment or opinion based on a statement or calculation result, making it the correct choice. Other options like 'Construct' and 'Deduce' do not specifically involve judgment.

Which command term example involves developing a representations of a food chain?

• Analyze

• Comment

• Construct

• Deduce

Answer explanation

The command term 'Construct' involves creating a representation, such as a food chain diagram. This requires organizing and illustrating the relationships between different organisms, making it the correct choice.

What does the example for the command term "Deduce" involve?

• Analyzing a graph

• Commenting on data

• reaching a conclusion from bar charts

• Constructing a diagram

Answer explanation

The command term 'Deduce' involves reaching a conclusion based on the information presented, such as interpreting data from bar charts. This choice directly aligns with the process of deducing insights from visual data representations.

What does the term "Predict" involve in scientific tasks?

• Assess the implications and limitations.

• Give an expected result.

• Discuss the advantages and disadvantages.

• Find the only possible answer.

Answer explanation

In scientific tasks, to "Predict" means to give an expected result based on data and analysis. This involves forecasting outcomes rather than assessing implications or discussing advantages.

Which task involves producing missing parts of a dichotomous key?

• Determine

• Design

• Evaluate

• Explain

Answer explanation

The task of producing missing parts of a dichotomous key is best described as 'Design'. This involves creating or structuring the key to include all necessary components for identification.

What is the task associated with evaluating CO2 concentrations' effects on oyster populations?

• Design a model.

• Find the only possible answer.

• Assess the implications and limitations of the dataset as a whole.

• Give an expected result.

Answer explanation

Assessing the implications and limitations of the dataset is crucial to understand how CO2 concentrations affect oyster populations, as it provides context for the data and its applicability to real-world scenarios.
