Drag each tile to the correct box.
The events describe the formation of an underwater sedimentary rock.
Place the events in chronological order.

After many years, the deposits
turn into a hard, solid rock.
The new rock is an aggregate
of several kinds of inorganic and
organic materials.

A gluing substance, such as
calcite or clay, carried in by
flowing water begins binding
the deposited material together.
The deposits begin to harden.

Weathering breaks existing
rocks into sediments.

Sediments and skeletal
remains of marine animals
begin depositing in a basin.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
