What is auxiliary energy in man subsidized solar powered ecosystem?

  1. Man and Machine

  2. wind and Rain

  3. Organic matter

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

In a man-subsidized solar-powered ecosystem, human labor and machinery provide the auxiliary energy needed to increase productivity beyond what natural solar energy alone could support.

Vulcanisation of Rubber is carried out to make it

  1. Soft

  2. Elastic

  3. Resistant to temperature changes

  4. Hard and inelastic
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Vulcanization is a chemical process that adds sulfur to rubber, creating cross-links between polymer chains. This makes the rubber more durable and resistant to temperature fluctuations.

Choose the correct answers from the alternatives given.
Most of biological diversity has probably arisen by:

  1. anagenesis

  2. cladogenesis

  3. sympatric speciation

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

Anagenesis and cladogenesis are the two main ways speciation occurs. One involved the slow transition of one species to another. Cladogenesis involved the separation of a species into two or more groups, with each group then becoming its own separate species.

Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one.
Sympatric speciation is a geographic mode of speciation due to geographical isolation new species is form.
So correct answer is B, cladogenesis.

  1. Human health

  2. Environment

  3. Plants

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

These pollutants (sulfur dioxide, nitrogen oxides, carbon dioxide, and suspended particulate matter) are major components of air pollution, which directly impacts human respiratory and cardiovascular health.

State whether the following statements are true or false.
Human intervention in natural community interactions usually makes the community more stable 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Humans cause a lot of destruction to the natural world, through deforestation, starting forest fires, farming, and building things. So, when we destroy the environment making it unstable, we allow a new environment where secondary succession begins to take place. It is still slow, and habitats take hundreds of years to rebuild, and often are nothing like the habitat before it.

So, the given option is 'False'.

Which ecosystem is very important for man to produce food and fiber?

  1. Man subsidized solar power ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Fuel power ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Man-subsidized solar-powered ecosystems, such as modern farms, use additional energy inputs to maximize the production of food and fiber compared to natural, unmanaged ecosystems.

Global warming could cause a rise in the sea level because

  1. Oceans expand as they get warmer

  2. Glaciers and ice-sheets melt

  3. Both of the above

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Melting of mass ice, glaciers around the world have caused increase in the sea level. The global warming is the main reason for the melting of ice, which are also a big reservoir of fresh water.
