There is only one possible path for each stage in the rock cycle. select the best answer from the choices provided t f

False

Rock cycle is a process of formation of rocks and it follows multiple alternative pathways and does not simply follows a single path. The rock cycle mainly result in formation of three types of rocks like igneous, sedimentary and metamorphic rocks. It mainly follows steps like withering of  igneous rock, erosion of particles, deposition of sediments, burial and compaction, formation of sedimentary rock from sediments after compaction, deformation of sedimentary rocks  and modifications to form metamorphic rocks, melting of metamorphic rock by hot magma present inside the earth, crystallization of magma into igneous rock. Nature does not follow a single pathway of rock formation, randomly steps are followed in the process of  rock formation.  

the sunflower because each experiment got the same results

hope this !

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
