Chapter 1 - Biology Flashcards
What are the steps to the scientific method?
The steps to the scientific method are observation, making inferences, forming hypotheses, conducting controlled experiments, collecting and analyzing data, and drawing conclusions.
What are the goals of science?
The goals of science are providing natural explanations for events in the natural world and explaining the world around us in terms of events and process that we can observe.
What scientific attitudes help generate new ideas?
These attitudes are curiosity, skepticism, open-mindedness, and creativity.
What are the characteristics of living things?
Living things are made up of basic units called cells, are based on a universal genetic code, obtain and use materials and energy, grow and develop, reproduce, respond to their environment, maintain a stable internal environment, and change over time.
What is a hypothesis?
A hypothesis is a scientific explanation for a set of observations that can be tested in ways that support or reject it.
What is a controlled experiment?
A controlled experiment is an experiment in which everything is constant except one variable.
What is biology?
Biology is the study of life.
What are the levels of organization?
In order, the levels of organization are individual, species, population, community, ecosystem, biome, and biosphere.
What is a theory?
A theory describes a well-tested explanation for a wide range of phenomena.
What is biogenesis?
Biogenesis is the production of new living organisms or organelles.
What is spontaneous generation?
Spontaneous generation is a disproved body of thought in which living organism can spawn from inanimate matter.
Describe Redi’s experiment.
Reid challenged the theory of spontaneous generation by placing food in closed jars. If the theory of spontaneous generation were accurate, maggots would spawn from the food. This was not the case.
What is an inference?
An inference is a logical interpretation based on what scientists already know.
Describe a microscope’s parts.
The base is on the bottom and it gives the microscope support. The stage is where you place your slides. The stage clips hold the slides in place. The lens at the top is known as the eyepiece lens. The objective lens are the lens closest to the object. The objective lens are connected to the eyepiece lens by the tube. Finally, the arm connects the tube to the base.
