Answer:
The atmosphere
Explanation:
The major reservoir of carbon in the abiotic environment is the atmosphere where it occurs as carbon dioxide. Atmospheric carbon dioxide is used by green plants for the synthesis of organic compounds through photosynthesis.
Answer:
The replication (exact duplication) of DNA begins with the unwinding of the double helix.
Explanation:
DNA replication is the first step of the central dogma of molecular biology which deals with the formation of 2 daughter DNA molecules from a single parental DNA.
The replcation begin with unwinding of DNA double helix by the breakage of hydrogen bonds between the complementary base pairs resulting in the formation of replication fork.
This incident occur by the catalytic activity of Helicase or dna B protein.
Answer: True
Explanation:
This was a bacterial fermentation that produced acetone, needed for cordite (explosive) manfacture. Species of Clostridium were used.
Answer:
Translation
Explanation:
This process occurs in the ribosomes. As the ribosome reads the codons on the mRNA the corresponding tRNA with the complementary anticodon is recruited. The tRNA brings in an amino acid (attached to it), and the amino acid is joined to the rest of the growing polypeptide chain. Each codon/anticodon specifies for a specific amino acid.
Answer:
<em>Lava eruptions can be “<u>fire fountains</u>” of liquid rock or thick, slow-moving rivers of molten material. Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called <u>tephra</u>.</em>
