A large class of molecules is called a macromolecule.
The type of inversion is Paracentric inversion.
There are two types of inversion at the chromosome level, depending on the centromere:
Paracentric inversions:
the centromere is not included in the inversion.
Pericentric inversions:
The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.
the structure that will form during synapsis is inversion loop.
These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.
C. It's necessary for the survival of the individual
The answer is <span>C) in warm, shallow seas.

About 500 million years ago, many multicellular organisms lived in
the seas. It was a rich life in shallow, warm, and continental
seas. The climate was favorable. Reef-forming corals, as well as the first true
vertebrates, some fish, appeared. Trilobites were diverse and
rich. The name trilobite means three lobes in which their body is divided. They lived in warm shallow seas. They avoided a great extinction of species in that time before they were <span>covered by sediment.</span>
