What do individuals do in science?
Individuals ask and answer questions about the universe, usually involving physical objects and measurable phenomena.
What is the difference between subjectivity and objectivity?
Subjectivity refers to opinion, while objectivity refers to truth.
What is the scientific method?
The scientific method provides a means of addressing questions as objectively as possible through observation, question, hypothesis, prediction, experiment, revision, and conclusion.
What are the steps involved in testing ideas?
Testing ideas involves forming hypotheses, predicting results, doing experiments or making observations, gathering data, and analyzing results.
What can data do in relation to a hypothesis?
The data may support a hypothesis, contradict a hypothesis, or inspire a revised or new hypothesis.
What are the three essential variables in an experiment?
The three essential variables are: 1. Independent (the variable that gets manipulated), 2. Dependent (the variable that changes as a result of the manipulation), 3. Controlled (the variable that doesn’t get any experimental treatment, helps to establish a baseline).
Why can science not address supernatural phenomena?
Science cannot address supernatural phenomena because hypotheses must be testable and easily falsifiable, and experiments must be repeatable and produce consistent results.
What is a theory in science?
In science, a theory is an accepted truth that has not yet been disproved.
What is biology?
Biology is the study of life, which is anything actively metabolizing and self-perpetuating.
What are the characteristics of life?
The characteristics of life include metabolism, reproduction, homeostasis, adaptation to change, response to change, organization, and interdependency.
What is metabolism?
Metabolism is the capacity to acquire and use energy to ensure survival.
What are heterotrophs and autotrophs?
Heterotrophs are organisms that have to eat other organisms to obtain their energy, while autotrophs obtain their energy from the sun through photosynthesis.
What is reproduction?
Reproduction is the ability for organisms to replace themselves.
What are the two types of reproduction?
The two types of reproduction are: 1. Asexual (one parent, cloning through mitosis and cytokinesis), 2. Sexual (two parents, adding variation through meiosis and fertilization).
What is homeostasis?
Homeostasis is the ability of organisms to maintain a constant internal condition.
What is adaptation to change?
Adaptation to change refers to the capacity of organisms to evolve.
What is evolution?
Evolution refers to long-term changes in populations that usually occur as a response to environmental conditions.
What is the response to change?
Response to change is how organisms respond to changes in the environment, such as moving to capture food or avoid predators.
What does organization refer to in biology?
Organization refers to how organisms are very organized, with cells having organized functions and DNA organized into genes.
What is interdependency?
Interdependency is when organisms require other organisms to live, such as for food, nutrients, oxygen, CO2, pollination, and symbiosis.
What are the core themes in the study of life?
The core themes include organization & emergent properties, expression & transmission of genetic information, energy transfer & transformation, interactions at many levels, and evolutionary change.
What are cells?
Cells are the fundamental units of life.
What is DNA?
DNA is the molecule of inheritance.
What is expression and transmission of genetic information?
Hereditary information is found as genes on chromosomes, passed down from generation to generation, with DNA holding all the information.
