Multiple Choice
A species has a better chance of surviving if it has greater variation in its:
A
habitat location
B
feeding schedule
C
body temperature
D
genetic makeup
Verified step by step guidance1
Understand the concept of genetic variation: Genetic variation refers to the differences in DNA sequences among individuals within a population. These differences can lead to variations in traits, which may improve survival and reproduction in changing environments.
Recognize the importance of genetic makeup: A species with greater genetic variation has a wider range of traits that can be beneficial in adapting to environmental changes, resisting diseases, or surviving predators.
Compare the options provided: Habitat location, feeding schedule, and body temperature are external or physiological factors, but they are not directly related to the genetic diversity of the species.
Focus on genetic makeup: Genetic makeup is the underlying factor that influences the traits and adaptability of a species. Greater genetic variation increases the likelihood of some individuals surviving under different conditions.
Conclude that genetic makeup is the correct answer: The survival of a species is strongly tied to its genetic diversity, as it provides the raw material for evolution and adaptation to environmental challenges.
