Study Notes
Biology
- Biology is the study of all living things.
Cellular Respiration
- Cellular respiration is the breaking down of glucose to produce ATP in the presence of oxygen.
- The Krebs cycle is when pyruvic acid is broken down.
Cell Division and Differentiation
- Mitosis is the division of a cell's nucleus, creating two identical nuclei.
- Cell differentiation is a change from a general cell type to a cell specialized for a specific task.
- Cell specialization is the result of differentiation, producing cells with specific functions.
Pigmentation and Reproduction
- Melanin provides skin color and UV protection.
- Sexual reproduction results in genetic variation in offspring.
Genetics
- Punnett squares are used to predict offspring genotypes.
- Homozygous describes an organism with two identical alleles for a gene.
- Heterozygous describes an organism with two different alleles for a gene.
- A pedigree is a diagram showing trait inheritance through generations.
- Sex-linked traits are more common in males than females.
- Mutations are changes in genetic material.
- Sickle cell disease is caused by the SS allele.
- Genetic variation is the difference in genes between individuals.
- A population is a group of the same species living in a shared area.
