  • What is Biology?

    Biology is the scientific study of life

  • What are the 9 properties of life

    Order, reproduction, growth, development, energy processing, regulation, response to the environment, and evolutionary adaptation.

  • What is the structural and functional unit of all life?

    The cell

  • What is the theory that the cell is the smallest unit of life?

    Cell Theory

  • What is order?

    Order is the idea that something is made in a specific way

    (like how we have 2 hands, or our head is on our shoulders)

  • What are the two types of reproduction?

    • Asexual reproduction: 1 cell splits and grows back to its original size

    • Multicellular reproduction (sexual reproduction): 2 cells combune and make another which grows

  • What is response to stimuli?

    How an organism changes based on its environment

    (like how you sweat when you're hot)

  • Why do we need energy?

    • all living things need energy

    • our bodies are always decomposing and energy allows us to rebuild it

  • How and why do adaptations happen?

    • The world is always changing and we need to change with it to survive

      • If change is slow, life will change with it over time

      • If change is fast, some life will go extinct

  • What is regulation/homeostasis?

    Regulating any body function

    (sweating and shivering to regulate body temp)

  • How many domains can be life be organised into?

    Three

  • Domains Bacteria and Archaea contain organisms with what types of cells?

    They contain organisms with simple cells

  • Domain Eukarya includes what?

    It includes various protists, and the kingdoms of Fungi, Plantae, and Animalia

    1. Domains Bacteria and Archaea are ____

    2. Domains Eukaraya are ____

    1. Prokaryotes

    2. Eukaryotes

  • What range of scales do biologists study life across?

    From the molecular level to the living planet

  • What are emergent properties?

    They are characteristics a system has but the individual parts do not have on their own

  • What are the emergent properties?

    Atom --> molecule --> cell --> tissue --> organ --> organ system --> organism -->population --> community --> ecosystem -->Biosphere

  • What is the most important emergent property?

    the cell

  • What is science?

    Science is a way of knowing , an approach to understanding the natural world

  • What does the scientific approach involve?

    observations, hypotheses, predictions, tests (experiments), observations, and analysis

  • What is a scientific theory?

    It is broad in scope and supported by a lot of evidence

  • What is a hypothesis

    It is often a strategized statement about what you want to learn that must be testable

  • What factor is manipulated called?

    Independant varible

  • What is the measure used to judge the outcome called

    The dependent varible

  • What does a controlled experiment compare

    an experimental group and a control group

  • What can using a control and experimental group demonstrate?

    the effects of a single varible

  • Can hypotheses be tested by using observational data?

    yes!

  • what is an example of observational data that was used to categorize red pandas into their own family?

    DNA sequencing

  • what is at the core of science?

    forming and testing hypotheses

  • What is the goal of science

    It is to understand natural phenomena

  • What is the goal of technology?

    It is to apply scientific knowlege for a certain purpose

  • What is an example of technology developed for science?

    the microscope

  • What is life distinguished by

    Its unity and diversity

  • What is the scientific explanation for the unity and diversity of life?

    evolution

  • Does each species on earth today have a family history?

    yes!

  • Where can evolutionary theory useful?

    medicine, conversation, and agriculture

  • What is an example of artificial selection?

    cows being breeded for certain things (milk cows, beef cows)

  • What is DNA responsible for?

    It is responsible for programming the activities of a cell and providing the "blueprint" for proteins

  • How many chromosomes does the normal person have

    23 pairs and a total of 46 individual chromosomes in each cell

  • How does the structure of our nerve cells relate to the function of them?

    They have long extensions which allows them to transmit impulses from your spine to your toes quickly

  • How many directions does energy flow in?

    just one!

  • what are ecosystems characterized by?

    They are characterized by the cycling of matter

    1. atmosphere and soil

    2. producers, consumers, and decomposers

    3. back to the environment

  • Using an approach called _______ _______, scientists attempt to model the behavior of biological systems by analyzing the interactions among their parts

    Systems biology
