question 47

Multiple Choice

What does this figure tell about the differences in extinction probabilities between planktotrophic and nonplanktotrophic species? Planktotrophic


Nonplanktotrophic

• A) Planktotrophic species tend to have relatively long durations and large geographic ranges, while nonplanktotrophic species have short durations and small geographic ranges.
• B) Planktotrophic species tend to have relatively long durations and small geographic ranges, while nonplanktotrophic species have short durations and large geographic ranges.
• C) Planktotrophic species tend to have relatively short durations and large geographic ranges, while nonplanktotrophic species have long durations and small geographic ranges.
• D) Planktotrophic species tend to have relatively short durations and small geographic ranges, while nonplanktotrophic species have long durations and large geographic ranges.

Definitions:

Double-Stranded DNA

DNA consisting of two complementary strands that wind around each other, forming a double helix structure.

Restriction Enzymes

Proteins used to cut DNA at specific sequences, essential tools in molecular biology for gene cloning and DNA modification.

Double-Stranded DNA

The structure of DNA in which two linear strands run in opposite directions (antiparallel) and are wound around each other, much like a twisted ladder, forming the characteristic double helix.

Sticky Ends

Single-stranded overhangs resulting from the action of restriction enzymes on DNA, which can be used to join DNA fragments together.
