Question 1: Which species of iguana is featured in today’s image?
- Marine iguana
- Lau banded iguana
- Campeche spiny-tailed iguana
Correct Answer: Marine iguana
Fact: Marine iguanas are found only on the Galápagos Islands. They have dark, spiny bodies with flattened tails that help them swim efficiently in the ocean. Known for their ability to dive and feed on algae, they can stay underwater for up to an hour. After feeding, they bask on land to regulate their body temperature.
Question 2: What key concept of biology did Charles Darwin propose in his famous theory?
- Natural selection
- Photosynthesis
- Cell division
Correct Answer: Natural selection
Fact: Charles Darwin’s concept of natural selection revolutionized biology. He proposed that species evolve over time through the process where the strongest, best-adapted individuals survive and reproduce, passing on their traits. This theory challenged traditional views of creation and introduced a scientific explanation for the diversity of life.
Question 3: Marine iguanas expel the saltwater they ingest by ….
- Sweating
- Sneezing
- Vomiting
Correct Answer: Sneezing
Fact: As marine iguanas dive into the ocean to graze on algae, they consume seawater, which contains high levels of salt. To manage this, they have specialized nasal glands that filter out excess salt. They expel it by sneezing, an adaptation that helps them to thrive in their saline environment without suffering the effects of too much salt in their system.
