Question

1. which of the following is always a nonrenewable natural resource? oil a wind b soil c fresh water d 17. natural selection depends on competition but not inherited differences. a b inherited differences but not competition. c both competition and inherited differences. d either competition or inherited differences. 18. the selective breeding of organisms by humans for specific characteristics is called ____ __. 19. \a testable idea that attempts to explain a phenomenon or answer a scientific question\ is the definition of a (an) __. 20. an inherited trait that increases an organisms chance of survival and reproduction in a certain environment is a(n) ____.

Explanation:

• Question 16: Non - renewable resources are those that do not replenish quickly. Oil is formed over millions of years from the remains of ancient organisms. Wind is a renewable resource as it is constantly replenished by the sun's heating of the atmosphere. Soil can be replenished through natural processes (although soil degradation is a concern), and fresh water is part of the water cycle (renewable).
• Question 17: Natural selection is the process by which organisms with favorable inherited traits are more likely to survive and reproduce. Competition for resources (such as food, mates, and living space) is a key part of this process. Organisms with inherited differences (variations) that make them better suited to their environment are selected for.
• Question 18: Selective breeding is also known as artificial selection. Humans choose which organisms will breed based on desired characteristics.
• Question 19: A hypothesis is a testable idea. It is an educated guess that can be tested through experiments or observations.
• Question 20: An adaptation is an inherited trait that helps an organism survive and reproduce in its environment.

Answer:

1. A. oil
2. C. both competition and inherited differences
3. artificial selection
4. hypothesis
5. adaptation
