I believe the answer is B.
when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.
C both. it changes in different regions
Answer: what is the major environmental factor limiting the number of autotrophs at great. Which abiotic factor has the least effect on the ability of aerobic organisms to live and, all living things that directly or indirectly affect the environment are known as. Which statement about the release of chemicals by willow trees is correct?
Explanation:
I believe the answer is that the turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pairs with another section of the same strand. Intrinsic termination of transcription in E.coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template.
