Expect to find in the pellet of a seagull bones and fur and feathers the seagull has eaten. The relatively small amount of indigestible bone and fur that remain will be compacted by their stomach muscles into a pellet similar to the owl’s.
Given, mass of isotope 1 = 39.06 amu
% abundance of isotope 1 = 10.00%
mass of isotope 2 = 42.14 amu
% abundance of isotope 2 = 90.00%
Average atomic mass
= [ (mass of isotope 1 x % abundance of isotope 1 ) + (mass of isotope 2 x % abundance of isotope 2 ) ]/ 100
= [(39.06 x 10) + (42.14 x 90)]/100
= (390.6 + 3792.6) / 100
= 4183.2/100
= 41.8 (to the nearest tenth)
Therefore, the weighted atomic mass of element Q is 41.8 amu.
Answer:
According to the evolution theory, the organisms that are better adapted have more chances to survive and to reproduce, thereby they also have more chance to perpetuate their own genes in the next generation. This statement can be divided into three properties. First, the adaptation (or adaptive fitness) of one organism is the ability to make use of the available resources in particular environmental conditions. Second, survival is defined as the ability to identify dangerous (environmental) conditions. Finally, reproduction can be defined as the ability to leave descendants (i.e., own offspring). The most important evolutionary forces that drive this process are mutations and recombination that generate biodiversity, these forces are capable of increasing the adaptive fitness in the next generation and generating speciation.
