what does "OLOGY" in Biology mean?

____ means "study of"

The phrase to determine if a object is living or non-living.

DOGSREACH

Dna

___ is all living things that have the ability to pass on their genetic material to their offspring.

Organization

Living things are ___ and structures have a function. Some examples can include in the following order: Molecules < Cells < Tissues < Organs < Organ Systems < Organism

Growth

This means that all living organisms grow

Stimulus Response

All living organisms respond to ___

Stimulus: Internal or external factor in the environment that causes a response (temperature

Reproduction

Living things have the ability to ___ either asexually or sexually.

Sexual ___ involves the egg and sperm.

Asexual ___ takes the form of cloning

Energy

All living things use___ in a process called metabolism. Also the sum of all chemical processes that occur in an organism.

Adaptations

Living things have ___ (traits) that make them well suited to their environment. Adaptive traits are passed on to future generations.

Cells

The smallest unit of life. All things are organized into ___ .

A note that living organisms are either multicellular or unicellular and grouped by their functions.

Homeostasis

___ is the state of biological balance. Many responses are an effort to reach ___ .

Some responses from living things can maintain a constant internal environment (temperature

Weight

This is the measurement of force exerted on an object by gravity.

Mass is measured in milligrams

Triple beam balance

Measures mass.

Length

Measured in meters.

Pseudoscience

False science.

Science does not investigate the following

Supernatural

Law

A rule that describes patterns observed in nature

Examples may include Law of Gravity

Theory

A logical explanation of WHY and HOW things work in nature based on observations and experimentation.

Some examples may include the big bang theory

Model

A diagram or 3d representation of an object or process

How many steps are in the scientific method?

Problem/Question

A ______ is a ______ that is based upon observations that can be tested through experimentation.

One example can be: What is the effect of SUNLIGHT on PLANT GROWTH.

Observation/Research

____ the world using your senses (light

Hypothesis/Prediction

_____ a solution based on your research using the phrase "if..then..because..."

Example: If sunlight has
a effect on plant growth

Experiment

______ the hypothesis with a step by step procedure. It is clear and detailed so another scientist can replicate your _____. List all the materials.

The two types of variables

Independent variable & Dependent variable

Independent Variable (IV)

What the investigator (YOU) changes
Known as the "Experimental Group"

Example: Amount of light is changed for each plant.

Dependent variable (DV)

Changes due to the IV

Control group

The group or sample is used as a standard for comparison

example: The plant in the dark is COMPARED to the experimental group (light)

Constants

The factors in the experiment that need to stay the same between the experimental group and the control group.

Example: amount of soil

Collect Data

Qualitative and Quanitive data would be collected during the experiment.

Qualitative Data

Descriptions of observations "What it looks like"

Example: Plant C has dried up and lost all its leaves.

Quanitative Data

Numerical measurements "Numbers with units"

Example: 15 cm.

Analyze Results

Display data using a graph to show "patterns"

Example: Line graph

Precision

How close the measurements are to eachother.

Accuracy

How close a measurement is to the actual value

Conclusion

The solution to a problem

Report Findings

Present your information to others so they can replicate (duplicate/copy) your findings.

Retesting by other scientists can verify your results to be true.

What is the primary focus of all biological studies?

Knowing about the world of living things and how they perform off one another.

What is meant by this statement "Living things do not exist in isolation?"

It means that they are connected in one way or another
