In the nitrogen cycle, the conversion of atmospheric nitrogen to ammonia by bacteria is called:

The correct answer is B: Nitrogen fixation. Nitrogen fixation is the process where atmospheric N₂ is converted to ammonia by nitrogen-fixing bacteria, making it available to organisms.

A new allele arises in a small island population of 100 individuals. The allele frequency is 0.02. Over the next 10 generations without selection, what is most likely to happen?

The correct answer is A: The allele will be lost due to genetic drift. In small populations, genetic drift can cause alleles to be randomly lost. With frequency only 0.02 in a population of 100, the allele is vulnerable to random loss.

In Drosophila, the gene for white eyes (w) is X-linked recessive. A white-eyed female is crossed with a red-eyed male. What will be the phenotype of F1 females?

The correct answer is A: All red-eyed. White-eyed female (XwXw) × red-eyed male (XWY). F1 females receive Xw from mother and XW from father, making them XWXw (red-eyed carriers).

Which hormone is essential for the regulation of calcium and phosphate homeostasis?

The correct answer is C: Both parathyroid hormone and calcitonin. Both PTH and calcitonin regulate calcium-phosphate balance. PTH increases blood calcium while calcitonin decreases it through opposing mechanisms.

What is the primary application of AFLP (Amplified Fragment Length Polymorphism) in forensic biotechnology?

The correct answer is B: To generate DNA fingerprints for individual identification in criminal investigations. AFLP generates unique DNA fingerprints by analyzing polymorphic bands through selective amplification and is widely used in forensic identification and paternity testing.
