Which of the following describes a role of gravity in the formation of our solar system? I. In the early stages of solar system formation, a fragment of an interstellar cloud of dust and gas collapsed and began rotating under the influence of gravity.
II. The eight planets were originally orbiting a nearby star, and the Sun's gravity pulled those planets into orbit around the Sun.
III. Gravity caused small particles in the rotating solar nebula to stick together and form larger particles. This process repeated itself, forming larger and larger particles that eventually became planets.
IV. The combined gravities of the planets pulled the Sun away from a nearby star cluster and into the center of the solar system.

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
