Global warming is a phenomenon of rising the average temperature of the earth over the past 100 years.
The following would provide the best evidence to support the claim :
(A) Habitat loss would occur, leading to a decline in species diversity.
<h3>Global warming has a long term impact on the ecosystem</h3><h3 />
- The earth warming gases are carbon dioxide, methane, nitrous oxide, etc.
- As the earth will warm up, we will experience more extreme weather, heatwaves, and droughts.
- Due to heat, the glaciers are melting to a high extent.
- Due to the melting of the glaciers, the sea level is rising.
- Some animals are already experiencing extinction due to global warming.
- Due to the loss of habitat, there is a loss of diversity.
Thus, the correct option is: (A) Habitat loss would occur, leading to a decline in species diversity.

Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
