Georgia Milestone Biology Review

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

A team of scientist is studying fossils of early reptiles and birds. Which aspect of fossil evidence is MOST LIKELY to help the researchers begin to construct a phylogentics tree?

• The average number of offspring produced by each species

• The estimated number of reptile or bird species that are now extinct

• The number of modern-day reptile and bird species represented by the fossils

• The approximate date when each reptile or bird first appeared in the fossil record

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
