Select the correct sequence of biological method.
Solution
The correct sequence in the biological method starts with forming a hypothesis, followed by reasoning, developing a theory, and finally establishing a law.
Select the odd one
Solution
Ratio is the odd one out as it is a mathematical concept, whereas theory, law, and hypothesis are components of the scientific method.

Solution
A ratio is the comparison of two values.
What is a hypothesis?
Solution
A hypothesis is a tentative explanation for a phenomenon that can be tested and potentially falsified.

The first step in solving a biological problem is:
Solution
The first step in solving a biological problem is making observations.
Which type of reasoning uses "if-then" statements?
Solution
Deductive reasoning uses "if-then" statements to draw specific conclusions from general principles.
What is the final step of the scientific method?
Solution
The final step of the scientific method is developing a conclusion based on the results of the experiment.

A hypothesis is a testable explanation for an event or condition.
A well-tested explanation of natural phenomena is called a:
Solution
A theory is a well-tested explanation of natural phenomena.
What is the primary purpose of the scientific method?
Solution
The primary purpose of the scientific method is to answer questions about the natural world through systematic steps.
Which step in the biological method follows the formulation of a hypothesis?
Solution
The step that follows the formulation of a hypothesis in the biological method is experimentation.
What was the initial belief about the cause of malaria before scientific investigation?
Solution
The initial belief about the cause of malaria before scientific investigation was bad air.
Who first observed Plasmodium in the blood of malaria patients?
Solution
Laveran was the first to observe Plasmodium in the blood of malaria patients.
A hypothesis in the scientific process must be:
Solution
A hypothesis in the scientific process must be testable.
Inductive reasoning moves from:
Solution
Inductive reasoning moves from specific observations to broader generalizations.
The statement: "If Plasmodium causes malaria, then all patients should have it in their blood," is an example of:
Solution
The statement is an example of deductive reasoning, which uses "if-then" statements to draw specific conclusions from general principles.

Which statistical method compares two values as a quotient?
Solution
A ratio is a statistical method that compares two values as a quotient.
Which is an example of qualitative data?
Solution
An example of qualitative data is the smell of a chemical, which is descriptive and not numerical.
