- Question
Which of the following CANNOT be considered a single phase?
Options- A. a heterogeneous mixture
- B. a pure solid
- C. a pure liquid
- D. a homogeneous mixture
- Correct Answer
- a heterogeneous mixture
ExplanationA pure solid and a pure liquid are definitely a single phase because they are so united, or homogeneous. This leads to a homogeneous mixture also being a single phase.
Hence, the option that cannot be considered a single phase is A. a heterogeneous mixture.

Correct Answer: Both A & B
Explanation:
The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it.
Correct Answer: Kyoto Protocol
Explanation:
The concept of carbon credit for manufacturers originated with the Kyoto Agreement (Protocol) of 1997.
Correct Answer: Ichthyology
Explanation:
Ichthyology is the branch of biology devoted to the study of fish.
It is also known as Fish science which includes bony fishes (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha).
Correct Answer: sugars and phosphates
Explanation:
DNA is a double-stranded molecule twisted into a helix. The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. Deoxyribose, which is a pentose, and a phosphate group are the two molecules together form the two sides of the DNA. The rungs of the ladder are pairs of 4 types of nitrogen bases.
Correct Answer: it contains two different elements joined by chemical bond
Explanation:
We know that All compounds are molecules, but not all molecules are compounds.
Water is a molecule because it is made from atoms that have been chemically combined. It is also a compound because the atoms that make water are not all the same - some are oxygen and some are hydrogen.
Hence, Water is a molecule and a compound.
Correct Answer: Pertussis
Explanation:
DPT refers to a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis, and tetanus.
Pertussis refers to whooping cough.
Correct Answer: Electron transport chain
Correct Answer: Leather bags
Explanation:
Biodegradable substances can be broken down into simpler, harmless substances in nature with due course of time by the biological process such as action of microbes. They can be recycled as a part of food chain.
Here, Leather bags are biodegradable.
Correct Answer: Monsoon experiment
Explanation:
Monsoon experiment is abbreviated as MONEX.
The Monsoon Experiment is the core of the GARP Monsoon Subprogramme, which is a major international effort to achieve a better understanding of the Planetary monsoon circulation, the major seasonal perturbation of the general circulation of the atmosphere and the influence of the annual cycle of precipitation associated with the monsoon on the agriculture of the many populous nations of the region.
Hence, MONEX is associated with The Monsoon Experiment.
Correct Answer: Lactose
Explanation:
Lactose is the major carbohydrate in the milk of most species.
Lactose is a disaccharide composed of the monosaccharides D-glucose and D-galactose, joined in a ß-1,4-glycosidic linkage. The chemical name for lactose is 4-0-ß-D-galactopyranosyl-D-glucopyranose.
