Answer:
a. different species of birds can divide ecological spaces between them my matching the morphology to the food source.
Explanation:
Beak morphology allows the birds to select the suitable food type. The various species of Galapagos finches differ from each other in beak shape and size irrespective of their origin from common seed-eating stock.
The modification of beak shape and size into several directions allowed the finches to occupy the available empty ecological niches with respect to food types.
Diversification also reduced the competition between them and allowed the finches to colonize various ecological niches in accordance with their respective beak morphology.
Answer: Correct options B, D and E.
Explanation:
In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)
Then the fish are the most primitive (being directly related to the first ancestor)., E is true.
We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.
So D is also true.
We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,
C the amount will decrease because the body will want to conservate water
It is unchanged and can be used again for the same chemical reaction.
is the answer
When two experiments are identical except for one variable, the experiment is called a controlled experiment
