Section B — Short Questions

Differentiate between qualitative and quantitative observations, and state why one is considered more accurate than the other according to the text.
Describe the sequence of animal development as mentioned in Sura Al-Mominoon, Verse 14.
Explain how a hypothesis evolves into a theory, and how a theory eventually becomes a scientific law or principle.
List the four main characteristics of a scientific hypothesis as described in the biological method.

Section C — Creative / Conceptual

A biologist visits an agricultural greenhouse and notices that the crop plants in Section A show severe leaf discoloration and stunted growth, whereas plants in Section B are healthy.

Apply the biological method steps outlined in the text to investigate this issue.
- Formulate a testable hypothesis to explain the leaf discoloration based on textbook examples.
- Construct a corresponding deduction using an 'if-then' statement.
- Describe how you would set up an experimental group and a control group to test your deduction.
A medical research laboratory is studying abnormal cellular growth in tissue samples to identify disease causes and develop targeted bacterial remedies.

Relate the medical team's activities to the specific branches of biology discussed in the textbook.
- Identify the branch of biology concerned with uncontrolled cell growth and spread, such as cancer.
- Name the branches responsible for the microscopic study of tissues and the development of new antibiotics.
- Explain how anatomy and immunology contribute to medical advancements according to the text.
A scientific paper discusses the evolutionary connection of all living organisms through their dependence on water and describes biological constants that govern inheritance.

Analyze this scientific paper using the Islamic concepts and biological terminology provided in the textbook.
- Cite the Quranic verse reference that supports the concept that all living things were made from water, and state the average water content range in organisms.
- Define the term 'scientific law' as used when describing constants of nature.
- Identify the two specific scientific laws of inheritance or genetics mentioned as examples in the text.
