What gas makes up most of the atmosphere?

Correct Answer: monosaccharides and disaccharides

Explanation:

Simple carbohydrates are also called as Simple sugars. Monosaccharides and Disaccharides refers to simple carbohydrates.

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: 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: 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: 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: Nucleic acids

Explanation:

DNA stands for Deoxyribo nucleic acid. It is a nucleic acid made up of monomeric unit called Nucleotide.

A nucleotide consist of -

a) Sugar - Deoxyribose in DNA ( ribose in RNA)

b) An organic base- Adenine, cytosine, guanine.

Correct Answer: not less than 60 deg

Explanation:

Potentially hazardous foods are foods that might contain food poisoning bacteria and are capable of supporting growth of these bacteria or formation of toxins to levels that are unsafe for consumers, if the foods are not stored at correct temperatures. Toxins are poisonous chemicals produced by some types of bacteria.

The food can be left at room temperature until it reaches 60 deg C because food-poisoning bacteria will not multiply at 60 deg C or above. However, do not leave food cooling at room temperature unless you are sure that the temperature of the food is still at least above 60 C.

Correct Answer: Gradually

Correct Answer: The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core There are two types of Shadow zones: one for P waves and one for S waves P wave shadows between 104-140 degree, both sides; S wave shadow from 105 of one side to 105 of the other

Correct Answer: Sulphur dioxide

Explanation:

Air pollutants are solid particles, gases, and liquid droplets in the air that can adversely affect ecosystems and the health of humans.

 

Major ambient air pollutants include toxic metals, polycyclic aromatic hydrocarbons, benzene, particulate matter (PM), nitrogen oxides, sulfur oxides, carbon monoxide, and ozone. Power plants, factories, and vehicle and air traffic are the most important anthropogenic sources of air pollution.

 

In addition, natural sources such as wildfires and volcanic activity contribute to ambient air pollution.
