7 Characteristics common to all living organisms

-Reproduction

-Growth/development

-energy and matter use

-cells

-Order

What is not a characteristic of life?

Moving around

Reproduction is Asexual and Sexual

True

Energy matter use

Is where life REQUIRES energy, captured and expelled,

Cells…

refers to ALL organisms are cellular

Order is how

Life is organized

What is an example of order?

Classifying animal classes

Response to environment is how…

Life maintains internal constancy

Homeostasis is….

the process by which a cell or organism maintains equilibrium

Evolution is how..

is how species evolve

What is biology?

Biology is the study of life around us

What does Biology explore?

Explores how living organisms, grow, function, interact

What is the scientific method?

A systematic way scientists answer questions and explore how things work in the natural world 

What is a important key of the scientific method?

The scientific method is a tool for critical thinking, not a rigid recipe (scientists often loop back, revise ideas and repeat steps)

What is NOT a common MISCONCEPTION

Scientists often loop back, revise ideas and repeat steps

What is a Hypothesis?

Hypothesis is an educated guess that can be tested and can be written using the format  “if this happens, then __ this will occur”

What are the steps for the scientific method?

1. Making an Observation

2. Hypothesis/prediction

3. experiment

4. conclusion

What is the independent variable?

An independent variable is the characteristic you control and manipulate

between 2 or more groups

What is a dependent variable?

What the researcher measures to see if it changed (factor is the same)

ex: car races between 2 cars and the dependent variable is the amnt of miles staying the same

What is population?

 A group of same species in same area

What is an example of population?

heard of deer, bacterial culture

What is Demography?

The study of statistics relating to births and deaths in a population

What is population ecology?

The study of the factors that affect population size and composition

Why does Demography and population ecology matter?

Matters because it involves Human POP growth, Invasive species, Habitat destruction

,climate change

What is not one of the reasons why factors pop growth matters?

butts

What is not one of the factors that regulate pop growth

rain

Why is predators one of the factors that reg pop growth?

Contributing to mortality rate , prey and predator can become interlinked

What other factors reg pop growth

• Populations are dynamic

• Growth is limited by resources

• Environment shapes survival

• Data helps predict trends

What is relative abundance?

The amount of organisms in a specific species

What is an example of relative abundance?

If one species has a large population it means it has HIGH relative abundance

What is species richness?

The amount of diversity species in a population
