Themes of Biology
The study of life.
What is Biology?
A possible explanation to a question or problem that has not yet been tested.
What is a Hypothesis?
The two ways that data may be organized and presented.
1) Data tables 2) Graphs
The 8 requirements of all living things.
What are the Characteristics of Life?
Organisms that produce their own food.
What are Autotrophs?
An organism composed of many cells and the cells work together to perform tasks.
What is a Multicellular organism?
The variable that is deliberately changed by the researcher.
What is an Independent Variable?
The type of data that uses numbers; obtained by counting or measuring.
What is Quantitative data?
Plants make their own food through this process.
What is Photosynthesis?
The 4 most common elements found in living things.
Carbon, Hydrogen, Nitrogen, and Oxygen
The type of reproduction in which offspring are produced by two parents.
What is Sexual reproduction?
This can be formed after many hypotheses have been supported; explains the "why" something happens.
What is a Theory?
This type of data presentation is used to visually show changes of one variable against changes of a different variable when the data points are connected to each other.
What is a Line graph?
The stable internal environment that a cell maintains in respect to its external environment.
What is Homeostasis?
A group of cells that work together to perform a similar function.
What is a Tissue?
Organisms with favorable characteristics make them well suited for their environment and are more likely to survive, reproduce, and pass these traits to their offspring.
What is Natural Selection?
This group serves as a baseline to be compared against.
What is a Control group?
The measurable variable; plotted on the Y axis of a graph.
What is the Dependent Variable?
An organism that can NOT make its own food.
What is a Heterotroph?
The scientist who named "cells"
Who is Robert Hooke?
Cells of all living organisms are alike in these 3 ways.
1) Contain genetic information (DNA or RNA)
2) Enclosed in a cell membrane
3) Contain cytoplasm
Drawing conclusions based on previous evidence and reasoning
What is an Inference?
A scientist is studying how different nutrient levels effect the color of tomato plants' leaves. What type of data is the dependent variable?
What is Qualitative?
This must be present for aerobic respiration to occur.
What is Oxygen?
A group of individuals that can interbreed and produce fertile offspring.
What is a Species?
