Amphibians usually have lungs but they can also absorb oxygen through their moist skin. Their body temperature also varies according to their surroundings. Amphibians also reproduce by external fertilisation and lag eggs.

More likely to avoid extinction,
1-if we have a wide range of genetic variation, we are more likely to survive ( take a disease for an example if we all have the same genes for weak immunity then we all die, but if genetic variation exists its more likely that we survive)
2- larger population will mean more people, more people mean greater genetic variation due to sexual reproduction.
3-wide range of geographic choices decreases extinction because if an area is affected by a natural disaster the rest if the areas will survive
The answer is B. Speed up chemical reactions. Hope this helps.
Answer:
