Critically Endangered Corals: Fire corals (Millepora boschmai) - Question 2 of 5
2. Question
1 pointsCategory: Geography & EnvironmentWhich of the following are the reasons of lead poisoning?
1. Cosmetics
2. Pencil
3. Paints
Select the correct answer using the codes given below:Correct
Explanation: Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body.
Lead sometimes can also be found in:
•Soil. Lead particles from leaded gasoline or paint settle on soil and can last years. Lead-contaminated soil is still a major problem around highways and in some urban settings. Some soil close to walls of older houses contains lead.
•Household dust. Household dust can contain lead from lead paint chips or from contaminated soil brought in from outside.
•Pottery. Glazes found on some ceramics, china and porcelain can contain lead that can leach into food served or stored in the pottery.
•Toys. Lead is sometimes found in toys and other products produced abroad.
•Cosmetics. Tiro, an eye cosmetic from Nigeria, has been linked to lead poisoning.
•Herbal or folk remedies. Lead poisoning has been linked to greta and azarcon, traditional Hispanic medicines, as well as some from India, China and other countries.
•Mexican candy. Tamarind, an ingredient used in some candies made in Mexico, might contain lead.
•Lead bullets. Time spent at firing ranges can lead to exposure.
•Occupations. People are exposed to lead and can bring it home on their clothes when they work in auto repair, mining, pipe fitting, battery manufacturing, painting, construction and certain other fields.Incorrect

3. Question
1 pointsCategory: Geography & EnvironmentConsider the following with respect to nutrients:
1. Copper
2. Manganese
3. Zinc
4. Sulphur
Which of the following above is/are micro nutrients?Correct
Explanation: The essential elements can be divided into macronutrients and micronutrients. Nutrients that plants require in larger amounts are called macronutrients. About half of the essential elements are considered macronutrients: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. The first of these macronutrients, carbon (C), is required to form carbohydrates, proteins, nucleic acids, and many other compounds; it is, therefore, present in all macromolecules. On average, the dry weight (excluding water) of a cell is 50 percent carbon, making it a key part of plant bio-molecules. Micronutrients: are needed in very small amounts. Their adequate concentrations in plants are generally below the 100 parts per million (ppm) levels. The essential micronutrients are zinc (Zn), iron (Fe), manganese (Mn), boron (B), chlorine (Cl), copper (Cu), molybdenum (Mo), cobalt (Co), vanadium (V), sodium (Na), and silicon (Si). Deficiencies of the last four minerals are very rare. Sodium is probably essential for only a few plants indigenous to saline soils. Silicon may be considered more of a secondary or macronutrient but it is “quasiessential” in that it has been shown to enhance growth in certain laboratory experiments but plants grown in its absence still thrived. Silicon is second only to oxygen in its abundance in soil because most soil mineral are silicates or alumni-silicates.

- Question 4 of 5
4. Question
1 pointsCategory: Geography & EnvironmentWhich of the following given below are results of Eutrophication:
1. Harmful algal blooms
2. Dead zones
3. Fish kills
Which of the following codes below given is/are correct?Correct
Explanation: Eutrophication is a big word that describes a big problem in the nation’s estuaries. Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication-which begins with the increased load of nutrients to estuaries and coastal waters. The primary culprits in eutrophication appear to be excess nitrogen and phosphorus—from sources including fertilizer runoff and septic system effluent to atmospheric fallout from burning fossil fuels—which enter water bodies and fuel the overgrowth of algae, which, in turn, reduces water quality and degrades estuarine and coastal ecosystems. Eutrophication can also produce carbon dioxide, which lowers the PH of seawater (ocean acidification). This slows the growth of fish and shellfish, may prevent shell formation in bivalve mollusks, and reduces the catch of commercial and recreational fisheries, leading to smaller harvests and more expensive seafood.

1. Wetlands International is one of the UN Specialized agencies
2. Luc Hoffmann Medal was presented by Wetlands International for Wetland Science and Conservation
Which of the following codes below given is/are NOT correct?Correct
Explanation: Wetlands International is the global not-for-profit organization dedicated to the conservation and restoration of wetlands. Wetlands are the source of water that supports all forms of life. Despite our efforts to promote their importance, loss and damage to wetlands and their biodiversity continues. Our vision is a world where wetlands are treasured and nurtured for their beauty, the life they support and the resources they provide. The Wetlands International Luc Hoffmann Medal for Wetland Science and Conservation is awarded every triennium to honor Dr Luc Hoffmann, one of the inspirational and far-sighted founders of Wetlands International.
