The 6 most abundant element in life.
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulfur

Organelle that holds a cell's DNA.
Nucleus
100
The four bases of DNA.
Adenine, Guanine, Thymine, Cytosine.

An individual with two different alleles for a trait.
Heterozygous

Some species of ants collect aphids (another type of insect). They protect the aphids from predators and feed them pieces of leaves. The aphids produce a sugary material called honeydew that the ants eat for nutrition. This ecological relationship is called _
Mutualism

DNA is a nucleic acid, a polymer made of certain monomers
Nucleotides
200
One difference between plant and animal cells.
Plants have [cell walls, chloroplasts, and large vacuole].
Animal cells have centrioles.
200
One difference between DNA and RNA.
Number of strands (DNA = 2, RNA = 1)
Bases (DNA uses T, RNA uses U)
Sugar (DNA has deoxyribose, RNA has ribose)

A species of flower can have red or white flowers. When red and white flowers are crossed, some pink flowers are created. This trait shows a non-Mendelian pattern.
Incomplete Dominance

In this food chain the chameleon occupies a certain niche/role.
Secondary Consumer

The four main types of biomolecules.
Carbohydrates, Lipids/Fats, Proteins, Nucleic Acids

Cells reproduce by a process that creates two identical cells.
Mitosis
300
DNA contains genetic information. Copying it without errors is possible because replication is semi-conservative. Semi-conservative means ___
New DNA molecules contain one old strand (template) and one new strand.
300
What is one source of evidence for evolution (where can we see the results of evolution)
Fossils and comparative anatomy (homologous structures)
DNA sequences
Development of embryos

400 Joules of energy are available to producers, primary consumers have access to a certain amount of energy as well.

Photosynthesis uses sunlight to combine substances into a product.
CO2 + H2O -> Glucose (+ O2)

DNA is a very large molecule. When cells divide each molecule folds up into one form, but in interphase all the DNA exists in a tangled stringy form.
Folded = Chromosome
Unfolded = Chromatin

This disease is caused by mutations that alter cell reproduction genes.
Cancer

A cell is placed in a hypotonic solution. Water will move by osmosis.

Plants have chloroplasts and mitochondria. These two organelles have different functions.
Chloroplast - photosynthesis (food from light energy)
Mitochondria - respiration (energy from food)

Identify the mutation in this DNA sequence.
GGG CCA TGA TTC -> GGG CCA TCA TTC
Substitution/Point mutation (4th G -> C)

Mendel's Law of Segregation says that organisms have 2 copies of each gene but only pass on 1 copy to their offspring. There is biological reason/mechanism for this.
Meiosis (Germline/Reproductive cells create gametes, which separates homologous chromosomes)
