An organism has the following characteristics: low biotic potential; k-selected, iteroparous; heterotrophic, fed upon by top carnivores large body size (> 2m tall). this organism most likely would also have
a. seed cones
b. basidiocarps
c. exoskeleton
d. open circulatory system
e. vertebrae

e. vertebrate

Explanation:

The question states that the organism posses the following characteristics:

Option a is discarded as seed cones are produced by conifers which are autotrophics.

Option b is incorrect as basidiocarps are typical of Basidiomycetes (fungi) which are not large and are rarely consumed by carnivores.

Option c and d correspond to small animals (e.g. arthropods) and with usually high biotic potential and r-selected species which prioritizes high growth population rates and offspring.

Then, option e (vertebrate) is consistent with belong to a k-selected, low biotic potential, iteroparus, heterotrophic species (e.g. a mammal).

the answer is "a.) well–developed vascular system."

explanation:

it marks things for degradation via the proteasome. it alters there celluar location.
