Review #3

Having a standard taxonomic system benefits the scientific community by allowing scientists from all over the world to do which of the following?

• Have a common system for the classification or locations containing fossils
• Use a similar system to classify the impace of removing species from ecosystems
• Have a common understanding in the classification of organisms
• Understand how other scientists classify predator-prey relationships

In Madagascar scientists have discovered a moth, Xanthopan morganii praedicta, that has a 30.5 cmproboscis and feeds from and pollinates Darwin’s orchid, Angraecum sesquipedale. The orchid has anectar-producing tube that is 27.9 cm long. How is the moth’s proboscis size an adaptation to its environment?

• The moth can avoid larger animals.
• The moth can pollinate other flowers.
• The moth has little competition for food.
• The moth has time to feed during the day.

Some organisms have genes that improve their ability to survive and reproduce. If the genes alsohelp their offspring survive and reproduce, then which of the following will most likely increase?

• The frequency of the genes in one individual
• The frequency of the genes in the population
• The number of genes in one individual
• The number of genes in the population

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.  The fact that both these animals incubate their immature offspring in a pouch provides evidence that they--

• belong to the same species
• must range great distances to eat
• have very similar skeletal structures
• are descended from a common ancestor

Students studying a moth population in the woods of East Texas. The woods contained trees with bark that was mostly black.  Two years later a fungus attacked nearly all of the trees in the woods and the tree bark changed from black to patches of gray and white.  What happened?

• Their color genes have mutated.
• Their color is an inherited trait.
• They are two different species.
• They have environmentally caused variations in color genes.

The cladogram shows the evolution of land plants as indicated by fossil records.  Which discovery would change the validity of this cladogram?

• A large aquatic vascular plant about 200 million years old
• A species of algae that has existed for less than one million years
• A moss species that has existed for less than 380 million years
• A fossil of a fern more than 425 million years old

A biology student mistakenly thought that all types of plant cells are rigid and cannot move. Use the image to evaluate his statement and select the best response.

• Guard cells frequently change shape to open and close stomata.
• Epidermal cells shift past each other to help a leaf bend and fold.
• Palisade cells often switch places as they float in a matrix at the top of a leaf.
• Spongy cells constantly flatten to allow nutrients to move through vascular tissue.

• Organisms 1 and 2
• Organisms 3 and 4
• Organisms 1 and 4
• Organisms 2 and 3

• Africa
• North America
• Europe
• Asia
