CELLS/HBS
Plant and animal cells have a membrane-bound nucleus. What type of cell are plant and animal cells?
Eukaryote-"Eu" rhymes with "True"
Explain the difference between dominant and recessive alleles.
Dominant-the trait that always show up as the phenotype; represented by a capital letter.
Recessive-the trait that can only show up as the phenotype as homozygous recessive; two lowercase letters
What is the process that increases the chance of an organism's ability to survive and reproduce?
Natural selection
What is the correct order of the levels of organization from the most broad to the most specific?
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What do arrows on food chains or food webs demonstrate?
Arrows show how the energy flows from one organism to another.
List the order of cellular organization from LEAST to MOST complex.
cells, tissues, organs, organ systems, and organisms
What is the shape of a DNA called, and what makes up the sides of a DNA molecule?
Double helix; phosphate that alternates with deoxyribose
What are differences in traits among individuals of the same species called?
Variation
Which kingdom's organisms are unicellular and have characteristics of both plants and animals?
What breaks down organisms and recycles nutrients?
decomposers

lungs, kidneys
What is the complementary DNA strand of
ATGCCGAT
TACGGCTA;
Apples grow on Trees, Cars are parked in Garages
How does color variation in beetles help beetles survive their environment?
It helps them avoid predators through camouflage.
How are organisms grouped together?
similar characteristics, (must say similar)
At what point are abiotic factors introduced into the environment?
At the ecosystem level
All organ systems work together to maintain balance. What is this balance called?
Homeostasis
What is the difference between a gene and an allele?
Alleles are the different versions of a gene, represented by letters.
Genes are sections of DNA that codes for a specific trait.
What theory provides evidence that all organisms descended from early common ancestors?
Theory of Evolution
Which kingdoms have a nucleus?
Animalia, Fungi, Protista, and Plantae
Which organisms are found at the base because they capture the most energy?
Producers; 1/2 credit if only say plants.
Why do plant cells have BOTH chloroplasts and mitochondria. What does each organelle do?
Using (G) for the alleles, explain the possible genotypes of the children, if a parent with homozygous recessive alleles (g) is crossed with a parent who has heterozygous alleles.
50% Gg
50% gg
How did the Clean Air Act (1963) affect the light-colored moths? Did their population increase or decrease? Explain why.
The Clean Air Act (1963) made trees lighter, therefore, the light-colored moths' population increased because they were able to better camouflage on the lighter bark.
Who created the two part naming system for organisms and what is the name of the two-part naming system? What levels of classification make up the two-part naming system?
Carolus Linneaus, binomial nomenclature, genus and species.
What would happen to a forest ecosystem if ALL decomposters were removed? Why is their role critical to the ecosystem?
Nutrients would not cycle back into the soil after organisms die. Minerals and nutrients needed to sustain life would run out.
