Variables
This is the variable that the researcher things will change due to the treatment
What is the dependent (response) variable?
This is the smallest unit of life/where life begins in the hierarchy of biology
What is 'the cell?'
These organisms can make their own food
What are autotrophs?
This describes competition that occurs between two members of different species
What is interspecific competition?
This term refers to the part of a cell's life cycle between rounds of cell division
What is interphase?
This variable is what is being intentionally changed or manipulated by the scientist
What is the independent variable?
List the hierarchy of life from biomolecules to organisms
What is 'biomolecules > organelles > cells > tissues > organs > organ systems > organisms?'
These groups belong in domain Eukarya
What are plants, animals, protists, and fungi?
These organisms help maintain biodiversity of an area by 'propping up an ecosystem' in a way that is disproportionate to their population size
What are keystone species?
A cell in a hypertonic solution will
What is 'shrink and shrivel?'
These are the three major variables that can affect the rates of photosynthesis
What are 1) light levels, 2) temperature, and 3) CO2 levels?
List the different levels of the taxonomic hierarchy
What is 'Domain < Kingdom < Phylum < Class < Order < Family < Genus < species < subspecies (if applicable - most organisms don't go down to subspecies level)?'
These are the three major reasons why all heterotrophs rely on autotrophs for survival
What are 1) oxygen production, 2) food production, 3) removal of carbon from the atmosphere?
This refers to the orderly process in which one plant community replaces another over time, in an area where no community (or soil layer) has existed before
These are the three major parts of cell theory
What is 1) all cells come from preexisting cells, 2) cells are the basic unit of structure and function, and 3) all organisms are made up of one or more cells?
What major variables or factors will cause a population to change over time (aka - what factors will prevent a population from reaching equilibrium?)
What are 1) mutations, 2) gene flow (immigration & emigration), 3) genetic drift, 4) nonrandom mating, and 5) natural selection?
These are the general rules for formatting the scientific name (genus and species) of an organism
What is 'the genus level is always capitalized; species level is never capitalized; if printed, both should be italicized; if handwritten, both should be underlined?'
The cells of sexually-reproducing eukaryotes can be divided into these two categories
What are 1) somatic cells (liver cells, bone cells, spleen cells, muscle cells) and 2) germ cells (sperm and egg cells)?
This is why apex predators are/are not always keystone species also
What is 'apex predators are also keystone species because they promote and maintain biodiversity in a way that is disproportionate to their population sizes?'
List three types of asexual cellular reproduction
What are 1) fragmentation, 2) binary fission, and 3) budding?
This major factor affects the rate of diffusion; briefly explain how diffusion is affected
What is 'the steepness of the gradient; the steeper the concentration gradient (the greater the imbalance between the two sides of the membrane), the faster diffusion will occur?'
List the hierarchy of DNA structure starting with chromatin
What is 'chromatin > nucleosomes > coils > super coils > chromosomes?'
Do autotrophs go through cellular respiration? Why or why not?
What is 'Yes - because they also must break down food and create chemical energy to carry out cellular processes?'
What is 'because earth is a closed system; the only thing that can get in our atmosphere is heat energy from the sun and nothing can escape our atmosphere?'
What is 'TRUE - all cells must go through both processes; DNA replication happens only once during S phase and protein synthesis/gene expression happens constantly throughout the life of a cell?'
