Across
- 2. refers to the observable traits or characteristics of an organism, such as its appearance, behavior, and physiological features. It is influenced by both genetics and the environment.
- 4. the process by which living organisms produce new individuals.
- 7. the process by which traits or characteristics are passed from parents to their offspring. It involves the transmission of genetic information.
- 10. Charles __________, a scientist known for his theory of evolution by natural selection. He proposed that species change over time based on survival advantages.
- 12. refers to a group of similar organisms that can reproduce and produce fertile offspring. Members of the same species share common characteristics and genetic traits.
- 15. trait or characteristic that improves an organism's ability to survive and reproduce in its environment. It can result from changes in behavior, physiology, or structure over time.
- 16. refers to something that occurs in nature without human intervention. It can describe processes, features, or substances that are part of the environment.
- 17. a specific characteristic or feature of an organism, such as color, size, or behavior. Traits are often determined by an organism's genes.
- 18. refers to a process that favors certain traits or characteristics over others. In natural selection, it describes how individuals with advantageous traits are more likely to survive and reproduce.
- 19. refer to alterations or modifications in characteristics, behaviors, or conditions over time. In biology, changes can occur in populations through processes like evolution and adaptation.
- 20. is the scientific study of life and living organisms. It encompasses various fields, including genetics, ecology, and evolution, to understand how life functions and interacts.
- 24. segments of DNA that carry genetic information. They determine specific traits and characteristics passed from parents to offspring.
- 26. refers to a beneficial trait or characteristic that helps an organism survive or reproduce better than others. It can improve the chances of success in a specific environment.
- 27. the ability of an organism to continue living and reproducing in its environment. It often depends on adapting to changing conditions and challenges.
Down
- 1. the genetic makeup of an organism. It determines traits inherited from parents.
- 3. refers to a group of individuals of the same species living in a specific area. It can be studied in terms of size, density, and distribution.
- 5. are changes in the DNA sequence of an organism's genes. They can occur naturally or due to environmental factors and may lead to new traits in a population.
- 6. the process where certain traits become more common in a population because they provide advantages for survival or reproduction. This is often called natural selection.
- 8. refers to traits or characteristics that can be passed from parents to their offspring through genes. These traits can be inherited in future generations.
- 9. a change in the DNA sequence of an organism. It can lead to new traits and may be beneficial, harmful, or neutral to the organism's survival.
- 11. refers to the variety of different types of organisms and their traits within a specific area or ecosystem. It includes genetic, species, and ecological differences.
- 12. refers to the challenges and competition organisms face to survive and reproduce in their environment. It can include competing for resources, avoiding predators, and adapting to changes.
- 13. refers to the surrounding conditions, including living and non-living elements, that affect an organism's life. It includes factors like climate, soil, and other organisms.
- 14. refers to the total collection of genes and their variations within a population. It includes all the genetic information available for inheritance in that group.
- 21. any living entity, such as a plant, animal, fungus, or microbe, that can carry out life processes independently. Organisms can be single-celled or multicellular.
- 22. means traits or characteristics passed down from parents to their offspring through genes. These traits are part of an organism's genetic makeup.
- 23. refers to traits or behaviors that improve an organism's chances of surviving and reproducing in its environment. These traits are often the result of evolution and natural selection.
- 25. process through which species change over time due to genetic variations and natural selection. It explains how different species arise and adapt to their environments.
