Answer:
Putative fossilized microorganisms
Explanation:
they were found in hydrothermal vent precipitates
Hope this helped a little!
The fossil fuel which come from fossilized plant material is oil/petroleum. The natural gas example methane is obtained when heat is applied to oil. The fossil fuels formed from both fossilized plant and marine organisms, but most fossils fuels are formed from dead plant buried with little or no oxygen.
Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.
Prokaryotic cells have flagellums. Eukaryotic has a nucleus
Answer:
When precipitation exceeds evapotranspiration and runoff in an area, the result is moist soil and possible flooding. Vegetation reduces runoff in an area but increases evapotranspiration. ... The volume of water moved by a stream in a given time period.
