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:

Low biotic potential: this means that the maximum amount of offpring that this species can produce under best environmental conditions is actually low. Typically, large organisms have much lower biotic potential than smaller ones. k-selected: this means that this species typically invest much more in fewer offspring rather than prioritizing many offspring.iteroparous: means that can reproduce many times over one organisms's lifetime.heterotrophic, fed upon by top carnivores large body size (> 2m tall): this shows that they are preys of large carnivores, thus it implies that the prey itself has a considerable size and it is not a plant.

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).

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun

This movement is also referred to as  glacial plucking
