Question 2 of 5
2. Question
Consider the following statements about Tundra Ecosystem
- Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy.
- The tundra acts as a significant carbon storage area due to slow decomposition rates.
- A layer of permanently frozen soil called permafrost lies beneath the surface of Tundra ecosystem.
How many of the statements given above are correct?
Correct
Solution (c)
Statement Analysis
Statement 1 Statement 2 Statement 3 Correct Correct Correct · Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. The world has three types of tundra:
· Arctic Tundra which occurs north of the taiga belt in the far Northern Hemisphere (It encompasses the land between the North Pole and the boreal forest, including parts of Canada, Russia, Greenland, Iceland, Norway, Sweden, and Finland.)
· Alpine tundra which prevails above the tree line in mountains worldwide (in various mountain ranges such as the Rockies, the Andes, the Himalayas, and the Alps).
· Antarctic tundra which includes several sub-Antarctic islands and parts of the continent of Antarctica
· Low temperatures: The average temperature is -34 to -6 degrees Celsius (-30 to 20 degrees Fahrenheit) in tundra region. · Short growing seasons: The summer growing season is just 50 to 60 days, when the sun shines up to 24 hours a day.
· Permafrost: A layer of permanently frozen soil lies beneath the surface, which can be a few inches to several feet thick.
· Flora: Mosses, lichens, sedges, cotton grass, birches etc.
· Fauna: Arctic foxes, snow geese, polar bears etc.
· Minimal precipitation: Despite often being compared to deserts in terms of moisture, the tundra receives low levels of precipitation, often as snow. · Limited biodiversity: The harsh conditions of the tundra result in fewer plant and animal species compared to other biomes.
· Carbon sink: The tundra acts as a significant carbon storage area due to slow decomposition rates in the cold environment.
Context: A study has warned the warming planet may alter the characteristics of tundra environments and could transform them from carbon sinks to carbon sources.

Question 4 of 5
4. Question
Consider the following statements about Biomarkers
- These are a physical, chemical, or biological characteristic that is present in the human body and can be measured.
- It includes biomolecules like carbohydrates, proteins, genes, DNA, RNA and platelets.
Choose the correct statements:
Correct
Solution (c)
Statement Analysis
Statement 1 Statement 2 Correct Correct · Biomarkers, short for ‘Biological Markers’ are a physical, chemical, or biological characteristic that is present in the human body, and measurable too. · The WHO defines a biomarker as “any measurement reflecting an interaction between a biological system and a potential hazard, which may be chemical, physical, or biological. The measured response may be functional and physiological, biochemical at the cellular level, or a molecular interaction”.
· Experts also call them molecular markers and signature molecules.
· They are indispensable in diagnosing disease, prescribing the right medication, right dosage, and even while designing new drugs.
· Biomarkers include biomolecules like carbohydrates, proteins, lipids, genes, DNA, RNA, platelets, enzymes, hormones, etc. Classification of Biomarkers:
Based on their source or location:
· Molecular – have biophysical properties, which allow their measurements in biological samples such as blood plasma, serum, cerebrospinal fluid, bronchoalveolar lavage, biopsy, urinalysis, and faecal analysis
· Radiographic – obtained from imaging studies, for example, bone mineral density
· Histologic – reflect biochemical or molecular alteration in cells, tissues, or fluids; for example, the staging and grading of cancers
· Physiologic – measures of body processes, for example, blood pressure, pulse rate, and heart rate
Based on roles/functions:
· Susceptibility/Risk Biomarkers: Indicate the person’s likelihood of developing a particular disease or condition in the near or distant future.
· Diagnostic Biomarkers: These are used to detect or confirm a particular disease or condition.
· Prognostic Biomarkers: In people who already are confirmed to have a disease, prognostic biomarkers can predict the likelihood of disease progression or relapse.
· Monitoring Biomarkers: These biomarkers are used for one or all of these reasons: to assess the stage or condition of the disease, to measure the exposure to a particular drug, and to measure exposure to an environmental agent.
· Predictive Biomarkers: These are used to identify individuals who have a higher likelihood of experiencing a strong outcome when exposed to a particular drug.
Context: Screening for blood biomarkers has been proposed as a potential way to diagnose cancer at earlier stages of the disease.

Question 5 of 5
5. Question
The term “Randomized Control Trials” is sometimes mentioned in the news in the context of?
Correct
Solution (a)
Option a Correct · Randomized Control Trials (RCTs) are a type of scientific experiment commonly used in medical research and other fields to assess the effectiveness of interventions or treatments. · In an RCT, participants are randomly assigned to either the treatment group, which receives the intervention being studied, or the control group, which does not receive the intervention or receives a placebo.
· This random assignment helps ensure that any differences observed between the two groups are due to the intervention itself and not to other factors.
· Randomized controlled trials (RCTs) have revolutionized medicine, providing an impartial way to assess treatment efficacy.
· They’ve led to major breakthroughs like aspirin preventing heart attacks, HIV antiretroviral therapies, and COVID-19 vaccines.
· RCTs tested streptomycin, the first effective antibiotic for TB, transforming TB management. Sir Austin Bradford Hill’s work introduced the ‘Bradford Hill Criteria,’ vital in modern epidemiology. These criteria confirmed links between factors like alcohol and heart disease, and smoking and lung cancer, shaping public health policies and perceptions.
· Kremer and fellow economists Abhijit Banerjee and Esther Duflo won the 2019 Nobel Prize winner in Economics for experiments using RTCs
