Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
Answer:
pollution levels in the atmosphere
Explanation:
One negative impact of increased production of goods is the increased levels of pollution in the atmosphere.
Pollution is the introduction of harmful substances into the environment beyond levels that are safe for life. The materials are the pollutants.
Production of goods or manufacturing generates a lot of waste with it. Air pollution is easily attributable to manufacturing.
Green house gases from combustion of fossil fuels to drive industrial processes generally leads to climate change.
Smokes and dusts can be produced by industrial processes and when scattered about causes pollution
