Problem: OPTIONS:
- mRNA
- chromosome
- antigen
- operon
Q: Answer the following question given this paragraph: Regulation of transcription in prokaryotes typically involves operons. An operon is a region of DNA that consists of one or more genes that encode the proteins needed for a specific function. The operon also includes a promoter and an operator. The operator is a region of the operon where regulatory proteins bind. It is located near the promoter and helps regulate transcription of the operon genes. Q: Which region of dna consists of one or more genes that encode the proteins needed for a specific function? A:
Answer: operon

Problem:OPTIONS:
- pollution
- habitat
- differentiation
- diversity

Answer the following question given this paragraph: Q: What is the term for many different types of animals within the same species? A:
****
A: diversity

Problem:OPTIONS:
- velocity
- momentum
- freezing
- stretching or compressing

Answer the following question given this paragraph: Springs like the ones in Figure below also have elastic force when they are stretched or compressed. And like stretchy materials, they return to their original shape when the stretching or compressing force is released. Because of these properties, springs are used in scales to measure weight. They also cushion the ride in a car and provide springy support beneath a mattress. Can you think of other uses of springs?. Q: What causes an elastic force in springs? A:
****
A:
stretching or compressing
