According to modern science, Earth is about 4.5 billion years old and written human history extends back about 10,000 years. Suppose the entire history of Earth is represented with a 10-meter-long timeline, with the birth of Earth on one end and today at the other end. a. What distance represents 1 billion years? b. How far from the end of the timeline does written human history begin?
A certain antihistamine is often prescribed for allergies. A typical dose for a 100-pound person is 19 mg every six hours. Complete parts (a) and (b) below. a. Following this dosage, how many 12.4 mg chewable tablets would be taken in a week? b. This antihistamine also comes in a liquid form with a concentration of 12.4 mg/8 mL. Following the prescribed dosage, how much liquid antihistamine should a 100-pound person take in a week?

Which of following is incorrect about the history of human
population growth?
In the Modern growth era, both population and income per capita
grow very fast.
In the Malthusian era, growth rates of both population and
income per capita are close to zero.
In the Modern growth era, population growth slows down and
income per capita grows fast.
In the post-Malthusian era, both population and income per
capita grow at a higher rate compared with the Malthusian era.

The half-life for the radioactive decay of U−238U−238 is 4.5
billion years and is independent of initial concentration.
Part A
How long will it take for 20% of the U−238 atoms in a sample of
U−238 to decay?
Express your answer using two significant figures.
Part B
If a sample of U−238 initially contained 1.1×1018
atoms when the universe was formed 13.8 billion years ago, how many
U−238 atoms will it contain today?
Express your answer using two significant figures.

(122.5 years), and the oldest cat was Crème Puff (38 years). The
oldest organism in North America is often cited to be a bristlecone
pine in California dated at 5065 years by ring count.. Still others
claim that the oldest plant is actually a creosote bush in the
Mojave desert, called King Clone, that is shaped as a ring that is

Science continuously moves forward and uncovers more and more
about the human body. We have made monumental strides in human
genetics and this has led to recent discussions about patenting
genes. This sits in front of the Supreme Court and could have a
major impact based upon the decision. Research the pros and cons of
this issue and share with the class.
