Question 8

The FtsZ protein is present in prokaryotes and in chloroplasts. The protein is structurally and functionally similar to tubulin proteins of eukaryotic cells. Which of the following is a likely conclusion to draw from this information?

Accepted Answer

Tubulin genes are evolutionarily derived from the gene that codes for the FtsZ protein.

Answer

FtsZ and tubulin proteins were both present in a common ancestor.

Answer

Microtubules are involved in the mechanics of photosynthesis.

Answer

The sequences of the genes encoding the FtsZ and tubulin proteins are identical.

Question 9

Which of the following statements best supports the claim that organisms share fundamental processes as a result of evolution?

Accepted Answer

All organisms share a genetic code organized into triplet codons, making it possible for one organism to express a gene from another organism.

Answer

All organisms that are introduced into new environments have the capacity to fill vacant ecological roles.

Answer

All organisms have the ability to utilize oxygen to harness energy from the chemical breakdown of organic compounds.

Answer

All organisms possess structures such as chloroplasts and mitochondria within their cells that reflect past symbiotic relationships between prokaryotic precursors.

Which of the following best describes the concept of natural selection?

Accepted Answer

A process where organisms better adapted to their environment tend to survive and produce more offspring

Answer

A random change in the DNA sequence of an organism

Answer

The movement of individuals from one population to another

Answer

The intentional breeding of organisms to produce desired traits
