The p53 gene is a tumor that suppresses a protein commonly called protein 53. The gene is important in regulating the cell cycle and suppressing tumors. Which of the following is an example of a cellular response to a mutation to the p53 gene? A mutation to the p53 gene will result in excessive cell growth and division.
A mutation to the p53 gene will not cause any changes to the signal transduction pathway.
A mutation to the p53 gene will immediately stop the signal pathway.
A mutation to the p53 gene will change the relay molecules but will elicit the same response.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
