Simple inorganic substances released into environment is reused by

  1. Pyrolysis Reactor

  2. Pyrolysis Chamber

  3. Simple Reactor

  4. Simple chamber


Correct Option: A

Inorganic salts, mineral acids and metal compounds are:

  1. Inorganic pollutants

  2. Organic pollutants

  3. Air pollution

  4. All of them


Correct Option: A

Organisms, obtain energy from sunlight and make organic matter from inorganic substance, known as _____________________.

  1. Heterotrophs

  2. Autotrophs

  3. Consumers

  4. Decomposers


Correct Option: B

Simple sugar of blood is

  1. Galactose

  2. Lactose

  3. Sucrose

  4. Glucose


Correct Option: D
Explanation:

Glucose is a simple monosaccharide sugar. It is a hexose sugar. It is an aldose sugar. Ingested carbohydrates are broken down into monosaccharides which are absorbed in the intestine. Glucose is absorbed in intestine. Glucose is also chief form of sugar in blood and circulates in blood to supply energy to visceral organs.

Calcium is ____ nutrient.

  1. Organic

  2. Inorganic

  3. Both

  4. None of these


Correct Option: B
Explanation:

Calcium strengthens bones and teeth in our body. It is an inorganic substance which is later converted to its organic forms when it gets combined with carbon molecule.

Find the odd :

  1. Nitrogen

  2. Potassium

  3. Sulphur

  4. Ammonia


Correct Option: D
Explanation:

Nutrients obtained by plants and animals are classified into two groups organic and inorganic. Inorganic nutrients are those that are not easily found in animals or plants. They are always converted into their organic forms. Ammonia is an organic nutrient generally found in animals for synthesis of various metabolite.

Fertilizers supply this component that is essential for plant growth. Name the component.

  1. Carbon

  2. Calcium

  3. Nitrogen

  4. Potassium


Correct Option: C
Explanation:

Nitrogen is one such element which is very important in plant growth because it is an essential part of the chlorophyll that is the site of photosynthesis.

Nitrogen is not found in the free state in the soil and the plants cannot take up nitrogen from the air directly so we add fertilizers that are rich in nitrogen and supply the plant with it.
Calcium and potassium are trace elements and are needed in small amounts and can be taken up from the soil. Plants take up carbon directly from the atmosphere.
So, the correct option is 'Nitrogen'

Plants require nitrogen along with carbohydrates. This nitrogen can be obtained by

  1. Rhizobium

  2. Vibrio

  3. Salmonella

  4. Felix


Correct Option: A
Explanation:

Rhizobium is a nitrogen-fixing bacteria found in symbiotic association with the root nodules of leguminous plants. 

For nitrogen fixation rhizobium needs an oxygen-free environment because oxygen acts as a poison and so it forms the association because the root nodules contain leg hemoglobin which is an oxygen scavenger. 
In return the plant gets Nitrogen.
So, the correct option is 'Rhizobium'

Which one includes others?

  1. Photosynthesis

  2. Catabolism

  3. Metabolism

  4. Anabolism


Correct Option: A
Explanation:

Photosynthesis is a metabolic process of formation of glucose from carbon dioxide and water in presence of light energy.

Anabolic processes are those in which small molecules combine to form large molecules. The photosynthesis is an anabolic process as small carbon and hydrogen molecule combine to form the glucose.
Catabolism is a process of breakdown of larger molecules into smaller once. The photolysis of water is a catabolic process.
So, the correct option is 'Photosynthesis'

Reduced coenzyme NADPH $(H^+)$ is produced in respiration during

  1. Glycolysis

  2. PPP

  3. Krebs cycle

  4. Terminal oxidation.


Correct Option: B
Explanation:

PPP or pentose phosphate pathway is an important pathway that takes place in the cytoplasm.

 It is an alternative path for the Krebs cycle and is the only pathway that forms reduced NADH. The enzyme transhydrogenase, that transfers the hydrogen of NADPH to NAD and forms NADH.
So, the correct option is 'PPP'
