Answer:

Fur color that closely matches the eucalyptus bark color

Explanation:

In terms of evolving from land dwellers to tree dwellers, the number of offspring does not matter. Although the ability to run faster is a good evolution for escaping predators, it does not help the koalas evolve to be better tree dwellers (how would you run using only the trees?). Communicating with their peers would be convenient for survival, but it does not help koalas become better tree dwellers. What does help koalas survive better by traveling through the trees is camouflaging with the bark of the tree to hide from predators.

Answer:

1. Intraspecific

2. speciation

3. fossil record

4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

7. Fossils provide a great many intermediaries that connect past species with their living descendants.

8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.

babymother [125]

Answer:

The correct answer is option D) "K".

Explanation:

In this example the wolf population is described by the equation "ΔN/Δt=rN(K−N)K". Even tough the variables are not defined in the question, we can conclude that the effect of the moose population will be given by a factor that has a positive effect in the wolf's population because "as moose populations increase, wolf populations also increase". The factor "K" fits the description because it gives a positive effect on "ΔN/Δt". "K" is a factor that multiplies "rN" at two different levels, therefore the higher the value of "K", the higher value of "ΔN/Δt" will be.

That is because being prokaryotic or eukaryotic doesn't depend on the size of the organism, but rather on the cellular structure. Both are eukaryotic because they have clearly defined nuclei and functioning organelles that are differentiated, unlike prokaryotic organisms.
