unit 5 vocabulary practice biology

Answer 1

Sure! Here’s a vocabulary practice tailored for a Unit 5 Biology course, often focused on topics like genetics, evolution, and ecology. Below are key terms with brief definitions. You might use these for practice quizzes or study sessions.

Vocabulary Terms

1. Gene - A segment of DNA that codes for a protein and determines a trait.
2. Allele - Different forms of a gene that can exist at a specific locus.
3. Dominant - An allele that expresses its phenotype even in the presence of a recessive allele.
4. Recessive - An allele that only expresses its phenotype when homozygous.
5. Homozygous - Having two identical alleles for a single trait (e.g., AA or aa).
6. Heterozygous - Having two different alleles for a single trait (e.g., Aa).
7. Phenotype - The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
8. Genotype - The genetic constitution of an individual organism, represented by its alleles.
9. Punnett Square - A diagram used to predict the genotypes of a genetic cross.
10. Natural Selection - The process by which individuals with favorable traits are more likely to reproduce, leading to changes in the traits of a population over time.
11. Evolution - The change in inherited characteristics of biological populations over successive generations.
12. Speciation - The formation of new and distinct species in the course of evolution.
13. Mutation - A change in a DNA sequence that can lead to variations in traits.
14. Homologous Structures - Body parts in different species that are similar due to shared ancestry.
15. Vestigial Structures - Body parts that have lost their original function through the course of evolution.
16. Ecology - The study of interactions between organisms and their environment.
17. Biodiversity - The variety of life in the world or in a particular habitat or ecosystem.
18. Carrying Capacity - The maximum number of individuals of a particular species that an environment can support without detrimental effects.
19. Symbiosis - A close and long-term interaction between two different species.
20. Ecological Succession - The process by which the structure of a biological community evolves over time.

Practice Activities

1. Matching: Match each term with its correct definition.

2. Fill in the Blanks: Use the vocabulary terms to complete sentences about genetics or ecology.

3. Multiple Choice: Create questions with four options for each term, where students must choose the correct definition.

4. Flashcards: Write the term on one side and the definition on the other for self-study.

5. Short Answer: Ask students to explain concepts such as "How does natural selection lead to evolution?" using the vocabulary words.
