The answer is K-selected.
The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.
The chromosomes would not be duplicated and meiosis would not be able to be completed after meiosis 1 (meiosis 1 could still occur as the gametes go from diploid to haploid).

Changes in the trilobite exoskeleton can be attributed to changing environments and competition for survival
Marble is a metamorphic rock.
Most of marble forms at Earth’s convergent plate boundaries where Earth’s crust is exposed to metamorphism (process in which sediments will pile over top each other on either sedimentary or igneous rock. The rocks will be exposed to extreme During metamorphism, marble can be exposed to hot magma body that will recrystallize the calcite (CaCO3) and its texture will change over time. Minerals in marble can also change. During this process, marble will eventually change to limestone because calcite contains other minerals such as micas, quartz, pyrite, iron oxides, and graphite.
