Correct Answer: Electron transport chain
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: a heterogeneous mixture
Explanation:
A 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: 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.
Correct Answer: Kuiper belt
Explanation:
Pluto dwells on the inner edge of the The Kuiper belt which is a belt of asteroids that lies on the outer edge of the solar system.
Pluto is a dwarf planet that is supposed to be no longer a planet and is still considered a planet because of its history in the solar system.
It takes 248 years to make one orbit around the sun. As to where it is, depends on time.
Correct Answer: monosaccharides and disaccharides
Explanation:
Simple carbohydrates are also called as Simple sugars. Monosaccharides and Disaccharides refers to simple carbohydrates.
Correct Answer: Nitrogen
Explanation:
Our atmosphere is made up of
78% Nitrogen,
21% Oxygen and
1% all other gases like argon, carbon dioxide, neon, and helium.
So, Nitrogen makes up the majority of our atmosphere.
