Select the INCORRECT pair.
Rice - digested in our body
Protein - digested in our body
Plastic - does not breakdown by the action of bacteria
Coal - digested in our body
Coal - digested in our body
Identify the option that describes a non-biological substance being processed by human digestion, as digestion is a biological process for organic nutrients.
Identify the option that describes a non-biological substance being processed by human digestion, as digestion is a biological process for organic nutrients.
Evaluate Biological Digestion
Digestion is the process of breaking down organic food (like rice/carbohydrates and proteins) into absorbable nutrients. Rice and Proteins are standard food items that our body digests.
Evaluate Non-Biological Substances
Plastic is a synthetic polymer that is not broken down by bacterial action (hence it is non-biodegradable). This statement is scientifically correct.
Evaluate Coal
Coal is a combustible black sedimentary rock, primarily carbon, and is not a biological food source. Our body cannot digest coal; it is an incorrect pairing.
A: Rice is a carbohydrate and is digested by our body. B: Protein is a nutrient digested by our body. C: Plastic is inert and cannot be broken down by biological bacteria, making this a correct statement about environmental science.
D is correct because coal is a mineral rock and not a food source that our body is capable of digesting.
In questions asking for the 'incorrect' pair, first identify the common theme (e.g., biological processes) and look for the odd-one-out that violates physical or biological laws.
