Energy changes forms from heat, to kenetic, to potential energy. However, the total energy is the atmosphere is conserved, meaning energy can only change forms, but cannot be produced.
Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.
The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.
Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.
Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.
