Now we start to focus on Biology!

Multiple Choice

"Bio" means life, so what do you think biology is the study of?

• space

• life

• physics

• chemistry

Living things get classified into 1 of these 3 groups!

Things fall into one of these two categories:

Multiple Select

Which of the following would be biotic factors? (check all that apply)

• rocks

• insects

• plants

• rain

• birds

Multiple Select

Which of the following would be abiotic factors? (check all that apply)

• bacteria

• soil

• trees

• mountains

• river

All living things share the characteristics we will discuss next, that's why they are...

The Characteristics of Life!

Multiple Choice

An example of a unicellular organism would be

• a tree

• a whale

• a bacteria cell

• a pangolin

Multiple Choice

A bacteria cell growing, then dividing making an exact copy of itself would be an example of

• sexual

  reproduction

• asexual

  reproduction

Multiple Choice

All living things on Earth contain DNA in their cells?

• True

• False

Multiple Select

What do you think could happen to an organism if homeostasis is lost for too long? (check all that apply)

• biological processes get disrupted

• organism can get ill/sick

• organism will be fine

• organisms could die

Multiple Choice

Most organisms must maintain a stable internal conditions to survive

• True

• False

Evolution

• Evolution is how populations of organisms change over time

• organisms better adapted to their environment are more likely to survive and reproduce, passing on their traits to offspring (Natural Selection)

• individual organisms do not evolve during their life, the population of organisms evolves over time

Multiple Choice

Evolution is how

• an individual organism changes during its lifetime

• a population of organisms changes over time

Next, we will learn about the

Biological Levels of Organization!

Multiple Choice

Which biological level contains a community and all the abiotic surroundings?

• population

• community

• ecosystem

• biome

Multiple Choice

Which biological level contains a group of organisms of the same species living in the same area?

• population

• community

• biome

• biosphere

Multiple Choice

Different populations that live together in a defined area is an example of a

• population

• community

• ecosystem
