Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.
Answer: If new species, studies come to the table and the classification is not compatible with them
Explanation: Like a new animal was discovered but even using the eight levels of classification scientists couldn't figure what the animal was
Answer:
The correct answer will be- DNA primers
Explanation:
The polymerase chain reaction is a widely used technique which replicates the DNA from a small sample of DNA in in-vitro conditions.
The mechanism of the Polymerase chain reaction is similar to the DNA replication mechanism which requires a DNA polymerase enzyme which in PCR is Taq polymerase and Primers which assists the DNA polymerase to begin the replication.
Since in the given question, the scientist added the DNA polymerase enzyme but forgot to add the single-stranded DNA called primers.
Therefore, primers are the correct answer.
