Answer:

evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)

Explanation:

En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.

If your heart beats 70 times per minute, everyday of the year, how many times does it beat in a year?
katrin2010 [14]

Answer:

36,792,000

Explanation:

Using some math, if you say that it beats at 70 pm, then you should look for how much it beats in an hour, which is 4200 (60x70). Then you have to take that number and multiply by 24, which is 100,800. In a day it beats about that amount. Then you take that number and multiply by 365, which is 36,792,000.
