quarter 1
lab safety. what do you do when something spills
tell the teacher asap
what does ATP stand for
Adenosine triphosphate
what are genetics
the field of biology that studies inheritance
what is ecology
the scientific study of the interactions among organisms and their environment
A student compares prokaryotic and eukaryotic cells. The student notes that one type lacks a nucleus.
Which cell type lacks a nucleus?
prokaryotic cells
what is a independent variable
the thing you change
what is aerobic respiration
efficient metabolic process in which cells use oxygen to break down glucose
what is a punnet square
a visual, checkerboard-like tool used in genetics to predict the potential genotypes (gene combinations) and phenotypes (physical traits) of offspring from two parents.
what is the difference between abiotic factors and biotic factors
abiotic: all non living components. ex. rock
biotic: all living components. ex. animals
Plant cells contain chloroplasts, while animal cells do not. This difference affects how each cell obtains energy.
What is the primary function of chloroplasts?
capturing light energy for photosynthesis
name one difference between a plant and animal cell
plant cells have a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole, while animal cells lack these. etc.
what is anaerobic respiration
a form of cellular respiration that produces energy (ATP) without oxygen
what is dna in the shape of
a double helix
what is a food web
A food web is a complex network of interconnected food chains that illustrates the feeding relationships and energy flow within an ecosystem.
Mitochondria have folded inner membranes that increase surface area. This structural feature supports their function.
Which function is most directly related to this structure?
producing atp
what is the difference between a theory and a law
A law is a set of observed facts and theory explains why those observed facts happen. etc
describe photosynthesis
the essential process where plants, algae, and certain bacteria convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
name the levels of classification
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
how many lobes are there in the brain. extra points to name them
four
frontal, pariteal, temporal, occipital
A scientist observes a cell with a nucleus, chloroplasts, and a large central vacuole. The scientist classifies the cell based on these features.
Which type of cell is being observed?
plant cell
what is an enzyme
a special type of protein that acts as a biological catalyst
name one difference between haploids vs diploids
Haploid cells contain one set of chromosomes, while diploid cells contain two sets. or. Haploid cells are produced by meiosis for reproduction , whereas diploid cells are created via mitosis for body tissues. etc.
what is the theory of natural selection. extra points for naming who came up with it
Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. Charles Darwin
what do B cells and T cells do?
B cells: make antibodies to neutralize pathogens.
T cells: destroy infected cells
The structure of organelles is closely related to their function. Changes in structure can affect how well a cell performs its processes.
Which conclusion is best supported?
C. organelle structure determines its function
