[Q]: (CNN) -- Women seeking an abortion in Texas will have to view a picture of the embryo or fetus and hear a description of its development before having the procedure, under a law that takes effect September 1. The bill stirred some controversy in Texas, but it easily passed through the state House and Senate, both of which are controlled by Republicans. It was signed into law Thursday by Republican Gov. Rick Perry. The law says that at least 24 hours before an abortion is performed, women must undergo a sonogram, a procedure that uses ultrasound to create an image. The doctor, then, is required to give, "in a manner understandable to a layperson, a verbal explanation of the results of the sonogram images, including a medical description of the dimensions of the embryo or fetus, the presence of cardiac activity, and the presence of external members and internal organs," the law states. There are some exceptions, including pregnancies that resulted from sexual assault, incest or other violations of law. Women seeking abortions also are exempt if the fetus has been found to have an irreversible medical condition that will cause a disability. "Governor Perry was pleased to sign this important legislation, which bolsters our efforts to protect life by ensuring Texans are fully informed when considering such an important decision," said his deputy press secretary, Lucy Nashed. Critics say the new law is unnecessary. "What no one is focusing on is that this is a mandate to humiliate women who want an abortion," said Yvonne Gutierrez, vice president for public affairs at the Planned Parenthood Trust of South Texas. Texas already requires a 24-hour consent period, and the new law will simply add emotional and financial costs to those seeking abortions, she said. <sep>What conditions allow women seeking abortions to not undergo this procedure?<sep>Pregnancies that resulted from sexual assault, incest or other violations of law are exempt
[A]: Yes


[Q]: Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age. <sep>What kind of fossils are used to date rock layers?<sep>Index fossils
[A]: Yes


[Q]: So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity? <sep>How do gravity and friction differ?<sep>Friction only occurs between objects that are touching. Gravity can act between objects that are not touching.
[A]:
Yes
