What is the primary result of cell differentiation?
- Cells lose their ability to perform tasks.
- Cells become identical to each other.
- Cells replicate without changing their function.
- Cells change from a generalized to a specialized form. (correct)

What is the key feature that differentiates homozygous alleles from heterozygous alleles?
What is the key feature that differentiates homozygous alleles from heterozygous alleles?
- Homozygous alleles are always dominant.
- Homozygous alleles consist of two identical copies. (correct)
- Homozygous alleles are two different types.
- Heterozygous alleles produce more genetic variation.

What is mitosis?
What is mitosis?
The process where the nucleus of a cell divides, creating two identical nuclei. Think of it as a cell making an exact copy of itself.

What is a population?
A group of the same species living in a specific geographical area.

Study Notes
Biology Fundamentals
- Biology is the study of all living things.
Cellular Respiration and Processes
- Cellular Respiration (Aerobic): Breakdown of glucose to produce ATP using oxygen.
- Krebs Cycle: Pyruvic acid is metabolized.
- Mitosis: Cell nucleus divides creating two identical nuclei.
- Cell Differentiation: Generalized cells transform into specialized cells performing specific tasks.
- Cell Specialization: Cells with specific functions are created after differentiation.
- Melanin: Gives skin color and UV protection.
Reproduction and Genetics
- Sexual Reproduction: Involves genetic variation.
- Punnett Squares: Used to predict possible offspring genotypes.
- Homozygous: Two identical alleles present in an organism.
- Heterozygous: Two different alleles present in an organism.
- Pedigree: Diagram showing trait inheritance through relations.
- Sex-Linked Traits: More common in males than females.
- Mutations: Changes in genetic material.
- Sickle Cell Disease: Occurs when the SS allele is present.
- Genetic Variation: Differences in genes among individuals.
- Population: Group of the same species living in a common area.
Experimental Design and Biological Systems
- Control Group: Includes the independent and dependent variables; The variable is not changed.
- Experimental Group: The variable is changed.
- Independent Variable: Measured throughout the experiment.
- Dependent Variable: Manipulated variable in the experiment.
- Homeostasis: Essential for living things to function properly.
- Multicellular Organization: Cells → Tissues → Organs → Organ Systems.
