It's true because sun is reusable.
Answer:
<em>During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.</em>
<u><em>Explanation:</em></u>
<em>process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars.</em>
Answer:
It requires trolling your friends skills
Answer:
Fossil record gives evidence of evolution: Earliest land animals. A fossil called Tiktaalik has been found to be halfway between a fish and the earliest land animals
Explanation:
Fossil record documents the hystory life by fossils that have been found in the sedimentary rock layers
The fossil record matches the geologic record:
The oldest forms of life were much more simple than the newest forms of life.
Explanation:
The geologic record can be associated with sedimentary datable layers

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.
