Answer:
The density of the substance is 2, 14 g/ml.
Explanation:
The density (δ) of a substance is the relationship between its mass and its volume. It is calculated in this way:
δ= m/v= 75 g/ 35 ml= <em>2, 14 g/ml</em>
The correct answer is: silent mutation
There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:
1. Substitution-only one base is changed
• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon
• Missense mutations-when one nucleotide is substituted and a different codon is formed
• Silent mutations-when a nucleotide is substituted and the same amino acid is produced
2. Insertion- extra base pairs are inserted
3. Deletion- section of DNA is deleted
