what is a nucleotide?
a. the basic structural unit of dna and rna
b. a mutation that alters the genetic code
c. a type of protein that carries oxygen
d an enzyme that facilitates dna replication

what does adaptation refer to in the context of genetic mutations?
a. the ability to manipulate genetic traits
b. the inability to survive in different environments

Explanation:

1. Insertion mutation is when a new nucleotide is added to the DNA sequence.
2. Frameshift mutation occurs when insertion or deletion of nucleotides shifts the reading - frame of the genetic code.
3. Natural selection is the survival and reproduction of organisms with advantageous traits.
4. Genetic mutations are alterations in the DNA nucleotide sequence.
5. Genetic disorders are caused by abnormalities or mutations in DNA.
6. A nucleotide is the basic structural unit of DNA and RNA.
7. Adaptation in the context of genetic mutations refers to the ability to survive in different environments.

Answer:

1. c. Insertion mutation
