Answer:
Explanation:
Using its web as a gill, the diving-bell spider can live underwater with only occasional visits to the surface. The arachnid (Argyroneta aquatica) breathes air from a bubble that it grabs from the surface of water using fine hairs on its abdomen.
Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.
B- roots and steams that can store a lot of water
Answer:
the emperor penguin can hold their breath for 20 minutes
Explanation:
This is the chemical equation for photosynthesis
6CO2+6H2O--->C6H12O6+6O2
the inputs are the ones on the left:
carbon dioxide used in the calvin cycle and water used in the light-dependent reactions
the outputs are on the right
glucose resulted from the calvin cycle and oxygen resulted from the light dependent reactions
