Which types of organisms perform photosynthesis?
Autotrophs (plants, blue-green algae, some bacteria)
100
Compare and contrast asexual reproduction versus sexual reproduction.
Answers may vary.
100
These are the different forms of a gene.
What are alleles?
100
Describe what a Punnett square shows in each of the boxes.
All possible combinations of alleles (offspring) within a genetic cross.
100
The process of producing similar populations of genetically identical individuals is called __________.
What is cloning?
200
Which types of organisms perform cellular respiration?
All living things (or vast majority)
200
Describe the outcome of asexual reproduction.
Genetically identical offspring.
200
Describe the difference between dominant and recessive alleles.
Answers vary

DAILY DOUBLE: Draw a Punnett square for one homozygous dominant and one homozygous recessive parent.
Answers may vary
200
This is the intentional reproduction of individuals in a population that have desirable traits.
What is artificial selection a.k.a. selective breeding?
300
Why is homeostasis in a cell important to homeostasis in an organism?
Because organisms depend on their individual cells for the materials they need (food, oxygen, etc.) to stay alive.
300
Describe the outcome of sexual reproduction
Offspring have combined traits from both parents.
300
Define homozygous dominant. Define homozygous recessive.
Examples may vary.
300
DAILY DOUBLE: Explain how you could work backwards to determine a parent’s traits from their children’s using a Punnett square.
Answers may vary.
300
This is the use of modern technology to further explore the field of biology.
What is biotechnology?
400
Provide at least 4 ways in which cells maintain homeostasis (related to the organelles).
Cell growth, repair and reproduction (nucleus); cellular respiration (mitochondria); photosynthesis (chloroplast); waste management (cell membrane)
400
Explain the relationship between mitosis and asexual reproduction.
Both require only one original parent. Offspring are identical.
400
Describe the relationship between genotype and phenotype.
Genotype = genetic makeup ("type of gene") Phenotype = physical expression of trait
400
1. Describe what a pedigree is used for. 2. Explain what squares and circles represent in a pedigree. 3. Explain what shaded and unshaded means in a pedigree.
1. Shows the passage of traits and genetic relationships between members of a family. 2. Males and Females 3. Presence or absence of a trait
400
_____________ is the deliberate modification of the characteristics of an organism by manipulating its genetic material.
What is genetic engineering?
500
Demonstrate the complete reaction (reactants and products) of either Photosynthesis or Cellular Respiration.
Answers vary
500
Explain the advantages (benefits) of both asexual and sexual reproduction.
Asexual: less energy and time required; more frequent Sexual: better genetic diversity
500
Explain the relationship between nitrogen bases, genes, alleles and the DNA strand.
Nitrogen bases make up genes; genes come in different forms called alleles; and each DNA strand is made of linked genes.
500
Using a Punnett square explain how it is possible for two parents with a dominant phenotype to have a child with the recessive phenotype.
Answers may vary
500
What was the purpose of the Human Genome Project?
Identify the exact base-pair sequence of a human genome (DNA molecule) in order to better treat and identify genetic disorders.
