Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Electroplating is widely used in various industries for coating metal objects with a thin layer of a different metal. The layer of metal deposited has some desired property, which the metal of the object lacks.  Electroplating has wide usage in industries. It is also used in making inexpensive jewellery.

Multiple choice chemistry occurrence of carbon compounds in nature substances, objects and energy alternative fuels and energy sources alternative sources of energy

The main component of Bio gas is ___________.

  1. Methane

  2. Benzene

  3. Ethylene

  4. Ethane
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The main component of bio gas is methane.
Methane is also the important constituent (95%) of natural gas. Methane has high heat of combustion. Hence, it is used as fuel.
$CH _4 + 2O _2 \rightarrow CO _2 + 2H _2O + heat$

Multiple choice biology wastewater story personal and public cleanliness who will do this? basics of water pollution

Biogas is produced due to the .................. fermentation of the slurry of animals dung.

  1. Pesticides

  2. Anaerobic

  3. Coal

  4. Methane
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biogas is produced due to the anaerobic fermentation of the slurry of animals dung.
Microbial conversion of organic matter to methane has become attractive as a method of waste treatment and resource recovery. This process is anaerobic and is carried out by action of various groups of anaerobic bacteria.
Three basic points about this process are that most of the important bacteria involved in biogas production process are anaerobes and slow growing, a greater degree of metabolic specialization is observed in these anaerobic microorganisms and that most of the free energy present in the substrate is found in the terminal product methane. Since less energy is available for the growth of organism, less microbial biomass is produced and, consequently, disposal of sludge after the digestion may not be a major problem.

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

A non-renewable resource is

  1. Soil fertility

  2. Rainfall

  3. Biological species

  4. Wildlife
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A non-renewable source of energy is atype of resource which cannot be replenished back or take a very long time to replenish back, so biological species once lost cannot come back.

So, the correct option is 'Biological species'.

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

The resources that are derived from bio-mass of living organisms are called  ____________ resources.

  1. renewable

  2. non-renewable

  3. environmental

  4. natural
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Resources derived from biomass, such as plants and animals, are considered renewable because biological processes can regenerate them within a human-relevant timeframe.

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

The resources that can be replaced by natural ecological cycle is called

  1. Renewable

  2. non-renewable

  3. exhaustible

  4. natural
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Renewable resources are those that can be naturally replenished or replaced by ecological cycles, such as solar energy, water, and biomass.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Read the given statements and select the correct option. 
Statement 1 : Reforestation is the process of restoring a forest that once existed but was removed at some point of time in the past.
Statement 2 : Reforestation may occur naturally in a deforested area, however it can be speeded up by planting trees with due consideration to biodiversity that earlier existed in that area.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reforestation is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation. Reforestation can be used to rectify or improve the quality of human life by soaking up pollution and dust from the air, rebuild natural habitats and ecosystems, mitigate global warming since forests facilitate biosequestration of atmospheric carbon dioxide, and harvest for resources, particularly timber, but also non-timber forest products. Reforestation usually involves replanting areas of forest which have previously been damaged or destroyed, using native tree species. Sometimes forests are able to regenerate naturally if sufficient trees remain nearby and seeds can be dispersed into the deforested areas via animals or wind. However, areas of forest which have been severely degraded are unlikely to be able to regenerate naturally and need to be replanted by hand using native tree species.

So the correct option is 'both statements 1 and 2 are correct'.
