PLEASE HELP who ever can answer all the questions correctly i will give i really need help please help me:) \ ( 0o0) /

1. Sponges produce structures called gemmules, which are hard outer coatings protecting a reproductive bud during times of drought. What type of adaptation is this?
a.
Biochemical
b.
Ecological
c.
Structural
d.
Physiological

2. How does competition for resources lead to adaptations?

3. What is the purpose of hibernation?

4. Explain how the concept of the “survival of the fittest” relates to the theory of evolution.

5. Darwin thought the birds he collected from the Galapagos were different types of birds, but he learned that they were different types of finches that each came from a different island in the Galapagos. What was the significance of that discovery?

6. What discovery led Darwin to develop his theories on adaptation?
a.
The Galapagos islands contain a range of habitats.
b.
The Galapagos islands originate from volcanoes.
c.
The birds Darwin found in the Galapagos were different types of finches, not separate types of birds.
d.
Many of the organisms in the Galapagos lived in hostile environments.

7.What led Darwin to believe that organisms originate from a common ancestor?

8. Use the concept of natural selection to explain why organisms typically adapt over time.

9. In what year was On the Origin of Species published?
a.
1831
b.
1837
c.
1846
d.
1859

10. What are the five categories of adaptations?

1.b

2.Organisms that are best suited for survival in their environment will be able to compete for limited resources better than organisms that are not well suited to their environment.

3.Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.

4."survival of the fittest" is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

5.This led to Darwin developing his theory of adaptation.

Darwin's adaptation theory, also known as survival theory or survival of the fittest, ans states an organism's ability to adapt to changes in its environment and adjust accordingly over time

6.c

7.The similarities between different types of an organism can be explained by the theory that they all come from a common ancestor. The differences between them are due to changes over time that have developed through natural selection.

8.Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species.

9.d

10.migration, hibernation, dormancy, camouflage, and estivation

The five categories of adaptation are

Explanation:

Biochemical, structural, ecological, physiological, and behavioral
