B) 15-22 years old is the age range that fit the skull
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

Answer:
1. glycolysis
2. fermentation pathways
3. electron transport chain
4. less ATP
Explanation:
Frogs reproduce by a special kind of embrace called "amplexus" which is an external fertilization that does not occur inside the female's body.
During mating (amplexus), the male frog grasps the female frog's trunk with his forelimbs.
The female frog discharges eggs into the water and then the male frog sheds the sperms over those eggs.
