181: Gerontology is the study of:
(a) Process of ageing
(b) Growth of cells
(c) Birds
(d) Vegetables
182: In the context of CO2 emission and global Warming, what is the name of a market driven device under the UNFCC that allows developing countries to get funds/incentives from the developed countries to adopt better technologies that reduce greenhouse gas emissions?
(a) Carbon Footprint
(b) Carbon Credit Rating
(c) Clean Development Mechanism
(d) Emission Reduction Norm
Explanation:
The Clean Development Mechanism(CDM) is an arrangement under the Kyoto Protocol allowing industrialised countries with a greenhouse gas reduction commitment (called Annex B countries) to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. A crucial,feature of an approved CDM carbon project is that it has established that the planned reductions would not occur without the additional incentive provided by emission reductions credits, a concept known as "additionality". The CDM allows net global greenhouse gas emissions to be reduced at a much lower global cost by financing emissions reduction projects in
developing countries where costs are lower than in industrialized countries. However, in recent years, criticism against the mechanism has increased. The CDM is supervised by the CDM Executive Board (CDM EB) and is under the guidance of the Conference of the Parties(COP/MOP)of the United Nations Framework Convention on Climate Change (UNFCCC).
183: Ergotism is due to consumption of
(a) contaminated grains
(b) rotting vegetables
(c) contaminated water
(d) stale cooked food
Explanation:
Ergotism is due to consumption of contaminated grains of wheat, rye, oats, pearl millet etc. due to the infection of a fungal pathogen claviceps aps which releases 'Ergotin', a toxic substance causing ergotism.
184: Helium is used for respiration in deep water instead of nitrogen because:
(a) It is heavier than nitrogen
(b) It is lighter than nitrogen
(c) It mixes less in blood than nitrogen
(d) It helps oxygen burn more quickly
185: The complete conversion of glucose In the presence of oxygen into carbon dioxide and water with release of energy is called
(a) aerobic respiration
(b) anaerobic respiration
(c) glycolysis
(d) hydrolysis
