intro to biology Flashcards
What is the smallest level of organization that has PMC?
A cell
What are the three characteristics of life?
Program, Metabolism, Container
Why aren’t viruses considered living things?
They don’t have metabolism or a container
What does a scientific argument need to be sufficient?
Cause, Evidence, Reasoning
Are biomes bigger or smaller than an ecosystem? Why?
Biomes are bigger than ecosystems. Biomes are made up of all similar ecosystems around the planet.
Why do we use the Levels of Organization?
It helps us organize living things and understand what they are made up of.
Is all bacteria considered a living thing?
Yes
What is a cell in the context of Levels of Organization?
The smallest unit of life that can function independently
How are cause, evidence, and reasoning used together in scientific argumentation?
They are used to construct a logical explanation: the cause identifies what leads to an effect, the evidence supports the occurrence, and reasoning links the evidence to the cause.
What is an example of a program in a living organism?
DNA in cells, which contains the instructions for building proteins and regulating biological processes.
How do the “Community” and “Population” levels differ?
Population consists of all individuals of a single species living in a specific area, while a Community includes all the different species that interact within a particular area.
How do you use Evidence and Reasoning together in an argument?
Evidence provides the factual basis for a claim, and reasoning explains how the evidence supports the claim, making the argument more convincing.
What does Program refer to in the PMC framework?
Program refers to the genetic information (DNA or RNA) that directs the development, functioning, and reproduction of an organism.
Define Metabolism in the context of the PMC framework.
Metabolism is the set of life-sustaining chemical reactions in organisms that convert energy and matter into the materials needed for growth, reproduction, and maintenance.
What role does Container play in the PMC model?
The Container is the physical boundary, such as the cell membrane, that separates the organism’s internal environment from the external environment, maintaining homeostasis.
