Answer:

<h2>c. Division of these two groups occurred after the protostome developmental sequence appeared. </h2>

Explanation:

  • Protosomes are such types of organisms in which the mouth part developed first during embryonic development.
  • Those animals in which anus develop first are known as deuterostomes.
  •  This differentiation takes place during the embryonic development of the organisms.
  • Since lophotrochozoan and Ecdysozoa both are protostomes animals and categorized on the basis of molecular evidence.
  • Thus these two groups were formed after the appearance of the protostomes.

The above scenario is an example of an exponential growth.

<h3>What is an exponential growth?</h3>

An exponential growth can be defined as a situation in which the population size of a species of living organism grows faster and quickly as the population gets larger.

This ultimately implies that, an exponential growth generally result in a a population explosion over time.

In this scenario, we were told that the population of European starlings increased to hundreds of millions. Thus, this is an example of an exponential growth.
