8. Nitrogen fixing bacteria in root nodules of legume plants include:

• A Nitrobacter.

• B Azotobacter.

• C Nitrosomonas.

• D Rhizobium.

9. The type of classification system that can be used by a forest exploiter is:

• A Natural classification.

• B Artificial classification.

• C Phylogenetic classification.

• D Phenetic classification.

10. This tissue forms hard resilient layers in some plant parts like nuts and shells.

• A Tracheids.

• B Sclereids.

11. Which of the following is normally used in an experiment to analyze the content and estimate the rate of flow of metabolites in phloem?

• A Labelled carbon dioxide ($^{14}\text{CO}_2$).

• B Ringing in woody stem barks.

• C Stylets of feeding Aphids.

12. If a cell has 46 chromosomes at the beginning of mitosis then at anaphase there will be a total of:

• A 23 chromatids.

• B 23 chromosomes.

• C 46 chromosomes.

• D 92 chromosomes.

13. For a substance to qualify as an organic compound, it must have the following element.

Pro Revision Tips for These Biology Questions

• Watch the Chromosome Count (Question 12): This is a classic trap! Remember that during anaphase of mitosis, sister chromatids separate and are instantly considered individual, single-chromatid chromosomes moving to opposite poles. If you start with 46, doubling them temporarily during this phase gives you 92 chromosomes.

• Don’t Confuse Your Bacteria (Question 8 & 9): Pay close attention to ecological cycles. While Nitrosomonas and Nitrobacter are critical for nitrification in soil, only Rhizobium forms that distinct symbiotic, nitrogen-fixing partnership inside the root nodules of legumes.
