Answer:
Carrying capacity- maximum population size of a species that can be sustained in a specific environment
Emigration- departure from one's own natural home or region
Limiting factor-anything that can slow or stop the growth of a population
Population dynamics- how populations of species change over time
Answer:
a sequence of nitrogen bases
Explanation:
...the DNA molecule that packaged into thread-like structures. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer:
Mechanical isolation
Explanation:
mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.
The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
Limiting factors are what controls the population of an ecosystem. It also limits the kind of organisms that inhabit it. Limiting factors can be abiotic or biotic. Abiotic factors are the nonliving factors that affect the living ones. From the given options above, the only biotic limiting factor is vegetation. The correct answer would be option B.
