• Question 1 of 5 1. Question Which phenomenon describes the movement of tropical marine species towards the poles due to rising sea temperatures? (a) Marine heatwaves (b) Ocean fertilization (c) Polar amplification (d) Tropicalisation Correct Solution: D Tropicalisation is the term used to describe the mass movement of marine life where tropical marine species move from the equator towards the poles due to rising sea temperatures caused by climate change. This phenomenon is a direct consequence of global warming and its impact on ocean ecosystems. As waters warm, species adapted to tropical conditions extend their range towards higher latitudes, while temperate species retreat. This shift can have profound effects on marine ecosystems, altering food webs, species interactions, and potentially impacting fisheries and coastal economies. Tropicalisation is a clear indicator of the far-reaching consequences of climate change on marine biodiversity and highlights the need for comprehensive strategies to mitigate and adapt to these changes in our oceans.

• Question 4 of 5 4. Question Consider the following statements about the impact of increased prokaryote dominance due to ocean warming: Increased prokaryote dominance could lead to a reduction in fish populations. The dominance of prokaryotes may enhance the ocean’s ability to absorb carbon emissions. The shift in marine ecosystems could have implications for the global food supply. How many of the above statements is/are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Statement 2 is incorrect. Ocean warming leads to increased prokaryote dominance, which significantly impacts marine ecosystems. As prokaryotes, particularly bacteria, become more prevalent, they can disrupt the marine food chain by outcompeting phytoplankton, which serve as the foundation of the oceanic food web. This decline in phytoplankton can result in a reduced food supply for higher trophic levels, including fish, ultimately leading to a decline in fish populations. Since fish are a vital source of protein for millions of people, this shift can have profound implications for global food security. Additionally, the increased dominance of prokaryotes does not enhance the ocean’s carbon absorption capacity. Instead, it may reduce it because prokaryote-rich ecosystems tend to promote carbon recycling within the water rather than sequestering it in deep ocean sediments. This disrupts the ocean’s natural role as a carbon sink, exacerbating climate change. Incorrect Solution: B Statement 2 is incorrect.

• Question 5 of 5 5. Question Consider the following statements regarding DNA profiling: DNA profiling involves analyzing the entire human genome to establish identity. It is increasingly accurate but can be affected by sample contamination. DNA profiling should not be the sole basis for establishing guilt or innocence in the justice system. How many of the above statements is/are incorrect? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A DNA profiling is a widely used forensic technique for identifying individuals based on unique genetic markers. However, it does not involve analyzing the entire human genome. Instead, it focuses on specific regions within the 0.1% of DNA that varies among individuals, particularly short tandem repeats (STRs), which provide highly distinctive genetic signatures. This makes Statement 1 incorrect. DNA profiling is highly accurate, but its reliability can be compromised by factors such as sample contamination, degradation, or mishandling, which may lead to errors in interpretation. Thus, Statement 2 is correct. While DNA evidence is a powerful tool in forensic investigations, it should not be the sole determinant of guilt or innocence. Other forms of evidence, including circumstantial and corroborative data, are necessary to ensure a fair legal outcome. Therefore, Statement 3 is correct.
