Question

review the interactive, then match the following: you will not use all terms) column a column b 1. mutations a. positive changes in dna can drive this process. 2. evolution b. changes in dna which can be neutral, good or bad. 3. diet and exercise c. may turn on or off certain genes. 4. dna d. can change due to copying errors and damage.

Explanation:

• Mutations: Mutations are changes in DNA. These changes can be neutral (no effect), good (beneficial), or bad (harmful). So, Mutations match with b.
• Evolution: Positive changes (beneficial mutations) in DNA can drive the process of evolution. Over time, these beneficial changes can accumulate in a population, leading to evolution. So, Evolution matches with a.
• Diet and exercise: Diet and exercise are environmental factors. Environmental factors can influence gene expression. They may turn on or off certain genes. So, Diet and exercise match with c.
• DNA: DNA can change due to copying errors (during DNA replication) and damage (from factors like radiation, chemicals etc.). So, DNA matches with d.

Answer:

1. b. Changes in DNA which can be neutral, good or bad.
2. a. Positive changes in DNA can drive this process.
3. c. May turn on or off certain genes.
4. d. Can change due to copying errors and damage.
