During Pangea, Madagascar and India were one landmass. The species of frogs were homogenous across the
landmass. However, after continental
drift that began approximately 88 years ago,
allopatric speciation occurred to form different species on the two continents.
The dusky salamanders on the two continents that could once reproduce viable offspring 88 years
ago, cannot reproduce viably today because
they have diverged into two different species now.
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. ... Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration.

Answer:
L = 17 m, W = 12 m
Explanation:
W = (L - 5) m
P = 2(L + W) = 58 m
Substitute W = L - 5 from the first equation into the second equation and get L:
2[L + (L - 5)] = 58
2(2L - 5) = 58
2L - 5 = 58/2 = 29
L = (29 + 5)/2 = 17
Then W = L - 5 = 17 - 5 = 12
