_____ is a change in the genetic characteristics in a population from

one generation to the next.

Evolution

_____ is the process that causes the characteristics of a population to

change in a way controlled by humans.

Artificial Selection

___ is a trait that increases an organism’s chance of survival.

Adaptation

____ is a trait that may be unintentionally selected by humans.

Resistance

___ is the process that causes characteristics in a population to change without human control.

Natural Selection

____ one species causes malaria.

Protist

____ some of these cause diseases such as athlete’s foot.

Fungi

___ E. coli is one of these.

Bacteria

___ some of these organisms have vertebrae.

Animals

____ factors are environmental factors that are associated with or result from activities

of living organisms.

Biotic

___ factors are environmental factors that are not associated with

activities of living organisms.

Abiotic

___ is a community of organisms and their abiotic environment.

Ecosystem

In order to survive, ecosystems need these basic components:

Energy, mineral nutrients, water, oxygen, and living organisms.

Most of the energy of an ecosystem comes from the ____.

Sun

___ are living things that carry out life processes independently.

Organisms

A species is a

Group of structurally and functionally similar individuals that preferentially

interbreed with members of their own kind to produce viable offspring.

A population is

The given number of a given species in a given area at a given time.

___ are groups of various species that live in the same habitat and interact with

each other.

Communities

___ are places where an organism usually lives.

Habitat

The levels of organization of an ecosystem in order from simplest to

most complex are:

Organism, species, population, community, ecosystem

___ observed that organisms in a population differ slightly from each

other in form, function, and behavior.

Charles Darwin

__ is the process by which individuals that have favorable variations and are better adapted to their environment

survive and reproduce more successfully than less well adapted individuals do.

Natural Selection

__ is the change in characteristics of a population from one generation to the next.

Evolution

__ is the process of becoming adapted to an environment.

Adaptation

___ can be an anatomical, physiological, or behavioral change that

improves a population’s ability to survive.

Adaptation

__ is the process of two species evolving in response to long-term interactions with each

other.

Coevolution

__ is the selective breeding of organisms, by humans, for specific desirable traits.

Artificial selection

__ is the ability of an organism to tolerate a chemical or disease-causing agent.

Resistance

The cells of animals, plants, fungi, and protists all contain a ____.

Nucleus

__ are microscopic, unicellular organisms that usually have a cell

wall and reproduce by cell division.

Bacteria

The bacterium ___ is found in the intestines of humans and other animals and helps

digest food and release vitamins that humans need.

E. coli

A __ is an organism whose cells have nuclei, rigid cell walls, and no

chlorophyll.

Fungus

A ___ is the reproductive structure of a fungus.

Mushroom

Some fungi cause diseases such as __.

___ are diverse organisms. Some like amoebas, are animal-like. Others are

plantlike, such as kelp, and some resemble fungi.

Protists

The protist ___ is the unicellular organisms that causes the disease malaria.

Plasmodium

__ are multicellular organisms that make their own food using light energy from the

sun and have cell walls.

Plants

Plants with no vascular tissue are called ____.

Nonvascular

Leaves and roots are connected by ___ tissue, which has thick cell walls and serves

as a system of tubes that carries ___.

Vascular; water and food.

___ plants lack specialized conducting tissues, roots, stems, and leaves.

Nonvascular

___ are woody vascular seed plants whose seeds are not enclosed by an ovary or fruit.

Gymnosperms

___ are flowering plants that produce sees within fruit.

Angiosperms

___ have cells with no cell walls, must get their food from an outside source, and are

mobile in at least one stage of their life cycle.

Animals

___ are animals that do not have backbones.

Invertebrates

More ___ exist on Earth than any other type of animal.

Insects

Insects are successful for many reasons, name two of these reasons.

___ are animals that have a backbone.

Vertebrates

___ are warm-blooded vertebrates with feathers.

Birds

__ are warm-blooded vertebrates that have fur and feed their young milk.

Mammals

Birds and mammals have the ability to maintain ___ which allows them to live in

cold areas, where other animals cannot live.

Body temperature

An example of an ecosystem is __.

Ecosystems do not have clear boundaries and things move from one

ecosystem to another. Provide an example that demonstrates this.

If one part of the ecosystem is destroyed or changes, what is affected?

The entire ecosystem

An important characteristic of a ___ is that its members usually breed

with one another rather than with members of others.

Population

Name two organisms that artificial selection is frequently practiced with

Conifers, such as pine trees, are ___ that bear cones.

Gymnosperms

Much of our lumber and paper comes from ___.

Gymnosperms

Gymnosperms have several adaptations that allow them to live in dry climates,

what is one of these adaptations?

The __ is the reproductive structure of a fungus.

Mushroom

All __ move around in their environment during at least one stage in their life cycle.

animals

Humans and insects are often enemies. What is one example of

this?

Damaging crops; spreading disease

What ecological job do fungus and bacteria perform?

Breaking down dead organic matter and food to release nutrients.

What is one example of a nonvascular plant?

Moss

Provide two examples of an angiosperm.

Provide three examples of an invertebrate.

What are the five groupings of vertebrates?

Mammals, birds, amphibians, reptiles, fish.

What does the prefix “a” mean?

Not/without

Can individuals adapt? Explain your answer.

No; populations can adapt but an individual cannot.

What are three examples of an ecosystem?

Provide five examples of mammals.

What is a reptile? Provide three examples of a reptile.

Cold-blooded, has scales.

What is an amphibian? Provide three examples of an amphibian.

Both lives, cold-blooded.

What is a fish? Provide three examples of fish.

Scales, breathes with gills, lives in water.

How do humans promote evolution?
