100 POINTS Cell phone use is very high by many people of all ages, a relatively recent behavior. Cell phones emit radiation in small amounts, which cells can absorb. Some recent research studies show this radiation may be causing health risks related to changes in DNA. Do you think people should be more careful with cell phone use? What are the pros and cons of having a cell phone with you at all times?

If a cell's main function is to produce proteins to be excreted, which organelles would you expect to be larger

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

How can a geological time scale best be reconstructed? a) comparing vestigial structures in living species b) comparing homologous structures in living species c) examining homologous structures in fossil remains d) examining the written records of scientists from past cultures
