Increase in concentration of a toxicant at successive trophic level is called
A)
Bio-magnification
B)
Succession
C)
Eutrophication
D)
Biotransformation
Step-by-step reasoning:
1. The question asks for the term describing the increase in concentration of a toxicant as it moves up the food chain (successive trophic levels).
2. Bio-magnification (or Biomagnification) occurs when persistent, fat-soluble toxins (like DDT or mercury) are ingested by organisms. Because these toxins are not easily metabolized or excreted, they accumulate in the tissues. When a predator eats many prey organisms, it consumes all the toxins accumulated in those prey, leading to a higher concentration of the toxin in the predator's body. This process repeats at every higher trophic level.
Analysis of other options:
- b. Succession: This refers to the process of change in the species structure of an ecological community over time (e.g., primary or secondary succession).
- c. Eutrophication: This is the process where a body of water becomes overly enriched with minerals and nutrients (like nitrogen and phosphorus), leading to excessive growth of algae and depletion of oxygen.
- d. Biotransformation: This is the chemical modification made by an organism on a chemical compound (usually a drug or a toxin) to make it easier to excrete from the body.

Which of the following organelles is the site of protein synthesis in a cell?
A)
Peroxysome
B)
Ribosome
C)
Mitochondria
D)
Nucleus
Step-by-step reasoning: 1. Protein synthesis is the process where amino acids are assembled into proteins based on genetic instructions. 2. Ribosomes are the cellular structures responsible for this process (translation), where they read messenger RNA (mRNA) and link amino acids together. 3. Analysis of other options: (a) Peroxisomes are involved in lipid metabolism and the detoxification of hydrogen peroxide. (c) Mitochondria are the 'powerhouses of the cell,' primarily responsible for ATP production via aerobic respiration. (d) The Nucleus houses the cell's genetic material (DNA) and is the site of transcription (DNA to mRNA), but not the actual synthesis of proteins. Therefore, the ribosome is the correct site for protein synthesis.

The concept of carbon credit originated from
A)
Kyoto protocol
B)
Montreal protocol
C)
Earth summit
D)
Doha round
The concept of carbon credits was formally introduced and operationalized by the Kyoto Protocol, an international treaty adopted in 1997 (and entered into force in 2005) that extended the 1992 United Nations Framework Convention on Climate Change (UNFCCC). The Kyoto Protocol established legally binding emission reduction targets for industrialized countries and introduced 'Flexible Mechanisms' to help countries meet these targets. One of these mechanisms is the Clean Development Mechanism (CDM), which allows a developed country to earn 'certified emission reduction' (CER) credits by investing in emission-reduction projects in developing countries. These credits can then be used to meet their own emission targets.
Why other options are incorrect:
- b. Montreal Protocol: This 1987 treaty focused on protecting the ozone layer by phasing out the production of ozone-depleting substances (like CFCs), not on carbon credits or greenhouse gas trading.
- c. Earth Summit: The 1992 Rio Earth Summit led to the creation of the UNFCCC, which provided the framework for climate action, but the specific market-based mechanism of carbon credits was developed later in the Kyoto Protocol.
- d. Doha round: This refers to a round of trade negotiations under the World Trade Organization (WTO) aimed at lowering trade barriers and promoting global trade, which is unrelated to the origin of carbon credits.
