Answer:
DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).
Explanation:
Which of the following events occurs directly after RNA polymerase recognizes the transcription start site of a gene? the DNA strand begins to unwind, separating the two strands.

Answer and explanation;
-The most important life processes in the oceans or sea water are photosynthesis and respiration. Photosynthesis by plants and other lower organisms uses sunlight to convert CO2 and H2O to a carbohydrate compound; O2 is a by-product of that reaction. Respiration is the process that all organisms use to recover the chemical energy stored in organic compounds. O2 is used to oxidize organic matter and release chemical energy; CO2 and H2O are by-products.
-The rates of photosynthesis and respiration are nearly balanced.all of the organic matter produced by photosynthetic algae is respired by consumer and decomposing organisms.
Answer:
The correct answer is "Koch's postulates".
Explanation:
The missing options of this question are:
a) spontaneous generation
b) Koch's postulates
c) epidemiology
d) vaccination
The correct answer is option b) "Koch's postulates".
Koch's postulates propose four criteria used to establish that a pathogen is responsible for a disease. In his famous experiments, Robert Koch was able to prove that <em>Bacillus anthracis</em> is the cause of anthrax by injecting to a mouse an isolated culture from the blood of an injected sheep. The scenario established in the question is very similar to anthrax, and the scientific approach to look for the pathogen of the disease is following the principles of Koch's postulates.
