Answer:
Adverse effect on the animals.
Explanation:
If the rabbit population suddenly shrank due to disease, it will adversely affected the population of eagle, fox and coyote because these animals depend on them through feeding. Eagle, fox and coyote feed on the rabbit so if the population of rabbit decreases, then there will be scarcity of food for these animals and as a result decrease occur in their populations so we can say that adverse effect occurs on the population of eagle, fox and coyote.
Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!
Invertebrates
in- = not
vertebra = spine
Their bodies taper to points at both the snout and the tail, reducing water resistance. Also decreasing drag -- and therefore noise -- are dermal denticles, sharp scales that cover the skin of most shark species. Rather than bone, sharks have cartilage, which is much lighter and more flexible. In addition, their livers produce squalene, a fatty oil that helps them remain afloat. Their pectoral fins allow them to quickly change direction, dive and swim upward.

Microevolution - Allele frequency changes in a certain population over an amount of generations, it can also be simply described as "an evolutionary change in populations".
