What is the difference between an independent and dependent variable?
An independent variable is the factor that you change in the experiment, while the dependent variable only changes based off of the independent variable.
What is one of the eight characteristics of living things as defined by your Biology book?
cellular organization, growth and development, response to stimuli, reproduction, metabolism (requiring and using energy), homeostasis (maintaining a stable internal environment), heredity(containing genetic information like DNA), and adaptation (evolution over time)
What are the five W’s to think about when finding a reliable source for school?
The Five W’s are…
Who, What, For what purpose, Where, When
How can you read a graduated cylinder?
place it on a flat surface, get eye-level with the liquid's curved surface (meniscus), and read the bottom of the curve for clear liquids (or top for mercury), estimating the final digit between markings for precision.
What is a mind map?
a visual diagram that organizes information around a central idea, using branches, colors, and images to show relationships between concepts,
A diagram where the numerical values of variables are represented by the height or length of lines or rectangles of equal width is describing which kind of graph?
Bar graph
How does carbon cycle through earth?
continuously moves carbon through Earth's atmosphere, oceans, land, and living organisms via fast biological processes (photosynthesis, respiration, decomposition) and slow geological processes (rock formation, fossil fuels), driven by energy from the sun, with humans impacting it by burning fossil fuels, releasing significant CO2
What makes a source O’Dowd-worthy/Trustworthy?
Having enough information, keeping the source being relevant to the time and topic.
What is the concept of ppm?
measures extremely small concentrations of a substance in a mixture, like chemicals in water or errors in manufacturing, indicating how many units of a substance exist for every million units of the total.
What is ecology?
the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
100 centimeters is how many meters?
1 meter
What are the the basic structures found in both plant and animal cells?
Both plant and animal cells are eukaryotic, sharing fundamental structures like the cell membrane, nucleus, cytoplasm, mitochondria, ribosomes, endoplasmic reticulum (ER), and Golgi apparatus,
Is a Mutation Random or Direct in change?
Random Change
What’s the difference between qualitative and quantitative observations?
Qualitative observations use words and quantitative observations use numbers.
What is the differentiate between a plant and animal cells based on appearance and organelles?
Plant cells have a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole, giving them a fixed rectangular shape; animal cells lack these, have irregular shapes, possess lysosomes and centrioles, and generally have smaller, temporary vacuoles, making them more flexible and varied in form.
What is one rule in the living lab?
No walking off the path is one answer but there are more too.
How do you set up a trophic pyramid?
To set up a trophic pyramid, you start with producers (plants/algae) at the base, then layer on primary consumers (herbivores), followed by secondary consumers (carnivores/omnivores eating herbivores), and then tertiary/quaternary consumers.
What is a Phenotype?
An individual's observable trait, such as (eye color and height)
how can you support your claim
provide credible and relevant evidence such as facts, data, expert opinions, or examples to prove its validity.
How does energy flow through a trophic pyramid?
representing energy flow and feeding levels in an ecosystem, using a structure that narrows at the top to show energy loss at each step, typically using food webs to identify organisms for each level.
What is a hypothesis?
A tentative statement about the relationship between 2 or more variables. It is a specific testable prediction about what you expect to happen in a study.
What is a keystone species?
a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
What is the difference between Common ancestor and most recent common ancestor?
A most recent ancestor is the youngest on the cladogram and the Common ancestor has two or more traits that relate to the most recent ancestor.
True or False all microscopes have ocular lenses.
True
What is affected when you remove a keystone species from an ecosystem?
dramatic shifts in population sizes, reduced biodiversity, altered habitats (like soil erosion or waterway health), and potentially the collapse or fundamental change of the entire ecosystem.
