Fluids fill in the spaces between the particles of sediment and crystallize to create a rock by
a Clastic
b Compaction
C Crystallization
d Cementation

D- Cementation

Explanation:

Cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock.

Hope this helps!

not sure but try c two haploid cells

explanation:

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
