An educated guess as to the answer of a scientific question
What is a hypothesis?
This type of bond is formed when an atom that has lost an electron is attracted to an atom that has gained an electron
What is an ionic bond?
The four organic biological molecules
What are proteins, carbohydrates, lipids, and nucleic acids?
Heritable changes in the line of descent over time
What is evolution?
The three domains of life
What are Bacteria, Archaea, and Eukarya
Photosynthesis takes place in this organelle
What is the chloroplast?
This organelle harvests energy from organic molecules to produce ATP needed for cellular work
What is the mitochondria?
When an animal cell is placed into a hypertonic solution,________
What is, it will shrivel?
These three organelles are found only in plant cells
What are the vacuole, chloroplast, and cell wall?
The two main types of cells
What are prokaryotic and eukaryotic?
6CO 2 + H 2 OC 6 H 12 O 6 + 6O 2 Is the overall equation for this process
What is photosynthesis?
A substance that can absorb visible light is called this
What is a pigment?
Anaerobic respiration involves glycolysis and only one of these two types of fermentation (give both types)
What are alcoholic or lactic acid fermentation?
The three steps of aerobic cellular respiration
What are glycolysis, Kreb’s cycle, and electron transfer?
The two interdependent pathways of photosynthesis
What are the light reactions and the Calvin cycle?
Division of the cytoplasm to form two new cells
What is cytokinesis?
This is the phase of mitosis in which the nuclear membranes form around each new cluster of chromosomes at the cell’s poles
What is telophase?
An animal cell containing 40 chromosomes divides by mitosis to form 2 daughter cells, each with this number of chromosomes
What is 40?
Down syndrome, a condition in which an individual has 3 copies of chromosome 21, is caused by an error in meiosis known as _______, which occurs more frequently as a woman’s spindle fibers degenerate with age.
What is nondisjunction?
This is the phase of meiosis in which homologous chromosome pairs separate and move to opposite poles
What is Anaphase I?
The alternate forms of a gene are called________
What are alleles?
A cross between a homozygous dominant individual and a homozygous recessive individual yield offspring that all have this genotype
What is heterozygous?
An individual with the genotype AaBB can produce gametes with the following genotypes
What are AB and aB?
The AB blood type is an example of this type of non- Mendelian inheritance
What is codominance?
During meiosis, genes of homologous chromosomes are sorted into gametes separately from the gene pairs on other homologous chromosomes, resulting in the shuffling of maternal and paternal chromosomes
What is Mendel’s Principle of Independent Assortment?
