Answer:
increased
Explanation:
because no matter what, there is more births than deaths rate for the hawks
Answer:
16 cells
Explanation:
The percentages of cells in each population represent the percent of the cell cycle a given cell spends in each phase, so it spends about 10-20% of its time in mitosis and 80-90% in interphase.

The answer is either A, the bottleneck effect or C, natural selection. The answer is most likely A because it is hinted that the predator fish was placed in the isolated stream. The predators eating the darters less than 5cm is natural selection though.
Answer:
Lizards and snakes are more genetically alike than lizards and birds.
Explanation:
A cladogram can be described as a diagram which shows the evolutionary histories among organisms. The organisms which are placed more closer together in a cladogram show that these organsims are more closer to one another and might have evolved from a common ancestor in the near past. These organisms show more similarities with each other as compared to other organisms in the cladogram.
As lizards and snakes are more closely related to one another, it shows that they are more genetically alike.
The population of frogs would exhibit competition due to the limited resources in the lake. Competition can be defined as the interaction among the species of organisms when resources are limited in an ecosystem. The type of competition observed in the above example of the lake with limited resources is called intraspecific competition as it is between the members of the same species competiting for the same resources. The species that do not compete will eventually die or get eliminated. This results in the change of population of frogs over time. Thus, competition is one among the forces that is responsible for natural selection.
