Answer:Amphibians evolved during the middle of the Devonian period (416 to 359 million years ago) from the lobe-finned fish of the vertebrate class Sarcopterygii. Species within the genus Ichthyostega (members of the Labyrinthodontia subclass) are considered by some scientists to be the earliest amphibians.
Explanation:
Dispositional traits are personality traits that remain stable and relatively unchanging from about age. They refer to the tendency of an individual to behave in stable and predicted ways.

Answer:
the one that you chose it the correct answer.
Explanation:
fall & rise.. The initial compensating response to an acute respiratory alkalosis is a modest decline in ECF bicarbonate concentration as the result of cellular buffering. Subsequent renal responses result in decreased ECF bicarbonate concentration through reduced renal bicarbonate reabsorption.
1-metaphase, since an ecuatorial plate is formed
2.prophase since the nuclear envelope is starting to dissapear
3.Telophase since new nucleae started to form around each separated genetic material
4.Interphase
5.Interphase
6.Interphase
7.anaphase since genetic material(chromsomes) is pulled to the poles of the cell
8.Interphase
9.Anaphase
10.Interphase
11.metaphase
12.telophase
13.Interphase
14.Prophase
