The first statement describes the environmental factor that affected the skipper butterflies.

When the birds became involved in the skipper butterflies ecosystem, they became a biotic environmental factor. The other answer choices are not environmental factors, but they are adaptations and examples of survival of the fittest.

Hope this helps! Good luck! :)

Prokaryotes whose cell walls do not contain peptidogly can
masya89 [10]

Answer:

Archaebacteria

Explanation:

Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.

These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.

The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes.  The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.

Thus, Archaebacteria is the correct answer.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.
