• fungi

• plants

• viruses

According to the cladogram, which is more closely related?

As plants divereged from a common ancestor,characteristic features that distinguished the main plant groups from one another. Which statement shows evolutionary sequence in which these features developed?

• Vascular tissue,seeds,flowers

• Seeds,vascular tissue, flowers

• Flowers, seeds, vascular tissue

At one time scientists classified all bacteria in a single kingdom. Today, prokaryotic organisms are instead classified in two domains (archaea and bacteria). Assume that a scientist has found several new types of prokaryotes to classify. She argues that all of these prokaryotes should be classified into domain archaea. What information BEST supports her argument?

• The prokaryotes lack a nucleus

• The prokaryotes have cell walls

• The prokaryotes cause human disease

• The prokaryotes grow only in hot springs

A student researched the similarities and differences and differences between viruses and organisms. Which statement BEST supports the argument that viruses share some similarities with living things?

• They both get energy from their environment

• They both contain proteins and nucleic acids

• They both reproduce on their own

• They both have a shell called a capsid

Which scientific information would be LEAST useful in constructing an argument supporting the endosymbiotic theory?

• Mitochondria and chloroplasts make copies of themselves by dividing

• Some eukaryotic cells have both mitochondria and chloroplasts

• Mitochondria and chloroplasts are about the same size as bacteria

• The ribosomes of mitochondria and chlroplasts are similar to those in prokaryotes

Corals live near the ocean surface in some warm water regions of the world. The corals provide a home for algae. The algae, in turn, produce food that is used by the corals. Which is a biotic factor in this ecosystem?

• The amount of sunlight that reaches the coral

• The coral population

• The salt content of the water

• The temperature of the water

Which biotic factor would be the MOST effective in maintaining homeostasis in an ecosystem?

• the absence of large trees

• the presence of many ponds

• the presence of many species

• the absence of predators
