Answer:
Hello!
The answer is C) substitution
Explanation:
Substitution:
A kind of mutation that involves the substitution of a single nucleotide by another, without changing the frame of reference of the DNA sequence. In this particular example, the thymine in the codon GAG (codes for glutamic acid) is being substituted by the base adenine, leaving the codon GTG (codes for the amino acid, valine).
The described substitution occurs in the case of the disease, sickle cell anemia that yields abnormal heamoglobin.
- A) A deletion removes a base from the DNA sequence. This alters the frame of reference of the mRNA.
- B) An insertion involves the addition of a base into the DNA sequence.
- D) A silent mutation substitutes a base in such as way that the new codon codes for the same amino acid, conserving the function and structure of the protein; therefore, silent mutations are harmless.
The answer is B because soil is not just to hold plants in the ground they support life such as worms

A generalist species is able to survive in a wide variety of environmental conditions and can make use of lots of different resources. Generalist species have a big niche. Humans, rabbits, house flies, and raccoons would all fall under the generalist species list.
A specialist species can only thrive is a small variety of environmental conditions and/or only has a limited diet. Specialist species have a small niche. Pandas, koalas, and salamanders would all fall under the specialist species list.
Answer:
The scientific mrthod is a process used by scientists to find answers to a question or to solve a problem. No there isn't just one because there are several versions of the scientific method. Some versions have more steps, while others may have only a few. Scientists can add steps, take out steps, revise, or make models.
