In the diagram below, each circle represents an individual. Each circle is connected by lines to other circles below it that represent offspring. So, each row is a separate generation of individuals that are related to each other. The pattern of each circle represents types of variation in the genes of these individuals. The text to the right explains what is happening to each generation of individuals. What scientific process is represented by this series of events? * Imagen sin leyenda
a. Natural selection
b. Species extinction
c. Primary succession

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
