BIO 101 Module 11

Life on Earth is approximately

3.6 billion years old

To which group are organisms in kingdom Fungi most closely related

Animalia

What are the 3 Domains

Archaea Bacteria Eukarya

All of the biological diversity of all of the living species on earth is called

Biodiversity

In what way are fungi similar to animals

Both take in food from the outside

As a whole, most bacteria are harmful to human life, which is why we have to be so careful in coming into contact with any bacteria

False

Cladistics is a unique field of study to biology because the relationships that we described have been proven to be correct based on analysis of DNA

False

True or false: Organisms on Earth are currently classified first as either plant or animal

False

Dr. Smith has discovered a bird that he believes is a new species. Dr. Wilson says he will only be convinced if Dr. Smith finds several more birds of the same type. Why might Dr. Wilson feel this way

He wants to be sure that the bird Dr. Smith found isn't just an unusual example of an already-described species

Members of the Kingdom ______________ are multicellular eukaryotes that make their own food using photosynthesis

Plantae

How are prokaryotes different from eukaryotes

Prokaryotes have no nucleus separating the DNA from the rest of the cell

Algae are classified as part of which group

Protista

Biologists who specialize in describing and categorizing species, and then organizing and categorizing the various species into groups that have a degree of relatedness are called

Systematists

In what way is a member of domain Archaea similar to a member of domain Bacteria

They are both prokaryotic cells

The primary reason they are not classified with living organism is that they are unable to maintain homeostasis and are incapable of growth or reproduction without the assistance of another organism

True

True or false: It's possible for the same species to be categorized under two different names in different natural history museums around the world

True

Which of these is a true statement about viruses

Viruses use host cells to make more viruses

Which group underwent a large increase in diversity during the Cambrian explosion

animals

According to the most current classifications, which of the following groups is the most different from all the others

bacteria

How do fungi obtain nutrients

by secreting chemicals that break down food and then absorbing it

An organism that is multicellular, relies on other organisms for food, and reproduces by spores would be classified in which kingdom

kingdom Fungi

An organism that is multicellular and makes its own food would be classified in which kingdom

kingdom Plantae

Of the four kingdoms in the domain Eukarya, which one is most likely to be split into two or more new kingdoms as scientists perform more genetic analyses on evolutionary relationships

kingdom Protista

Scientists would change the most current classification system if

more information became available on the evolutionary history of existing species

The Cambrian explosion is a period in Earth's history when what significant event occurred

multicellular animals first appeared

In order to construct an evolutionary classification of modern-day aquatic vertebrates, what is the the best source of information?

the DNA sequence

Which of the following animal traits would be of most interest to bioprospectors

the ability to produce food

What is the result of adaptive radiation

the diversification of one or a few species into a varied group of descendants

What does the main trunk at the far left of the "tree of life" represent?

the earliest common ancestor of all the organisms in the tree

Different phyla of fungi are distinguished from each other by what trait

the way they form spores
