7 Characteristics of Life
Different levels of organization
What is cell, tissue, organ, organ system, organism?
The two things that go into forming a hypothesis
What are questions and observations?
A normal standard against which the biologist can compare results of the experiment
What is the control group?
The part of the microscope that enlarges the image of the specimen
What is the objective lens?
The smallest unit that can perform all of life’s processes
What is a cell?
The definition of evolve
What is a change through time?
What can be formed from many correct hypotheses
What is a theory?
A group that is identical to the control group except for one factor
What is the experimental group?
The platform that supports a slide
What is a stage?
The formation of two new cells from an existing cell
What is cell division?
A physical or chemical change in the external or internal environment
What is a stimulus?
A statement scientists make about what is expected to happen if a hypothesis is true
What is a prediction?
The one factor that differentiates the control group from the experimental group
What is the independent (manipulated) variable?
A microscope that shines light through a specimen and has two lenses to magnify an image
What is a compound light microscope?
Organisms do this when they transmit hereditary information to their offspring
What is reproduce?
A stable internal environment
What is homeostasis?
When scientists who are experts in the field anonymously read and critique a paper
What is peer review?
The responding variable
What is the dependent variable?
A microscope that produces an enlarged image of the specimen by passing a beam of electrons through it
What is an electron microscope?
The process by which an organism become a mature adult
What is development?
The 7 characteristics of life
What is different levels of organization, response to stimuli, maintain homeostasis, metabolism, grow and develop, reproduce, and evolve?
The basic steps of the scientific method
What is make observations and ask questions, form a hypothesis, design an experiment, Collect and analyze data, draw a conclusion (repeat)?
A conclusion made on the basis of facts and previous knowledge rather than on direct observations.
What is an inference?
The two different types of electron microscopes
What are Transmission EM (TEM) and Scanning EM (SEM)?
The sum of all chemical reactions inside an organism that take in and transform energy and materials from the environment
What is metabolism?
