An ecosystem is a level of organization that includes living and non-living things.
Answer: Its possible genotypes are PPSS, PPSs, PpSS, and PpSs.
Explanation: If P represents the allele for purple kernel and S represents the allele for smooth seed shape; if P and S are dominant alleles, PP and Pp will manifest outwardly as purple kernel because P is dominant and will be able to express itself whether in a homozygous or heterozygous state. Similarly, SS and Ss will manifest outwardly as smooth seed shape because S is dominant and will be able to express itself whether in a homozygous or heterozygous state.
Therefore, PPSS, PPSs, PpSS, and PpSs will appear outwardly as purple kernel and smooth seed shaped corn plant.

Answer: Tension
Explanation: Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust. Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle.
