Q: Answer the following question given this paragraph: Superposition refers to the position of rock layers and their relative ages ( Figure below ). Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition. Q: Deeper layers of rock must be older than layers closer to the surface, this is the law of what? Choices: - erosion - diffraction - flux - superposition A:
A: superposition

Q: Answer the following question given this paragraph: Q: E. histolytica causes what kind of dysentery? Choices: - Spastic - cocklebur - spicule - amebic A:
A: amebic

Q: Answer the following question given this paragraph: The Process of Science Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? Science (from the Latin scientia, meaning "knowledge") can be defined as knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method. It becomes clear from this definition that the application of the scientific method plays a major role in science. The scientific method is a method of research with defined steps that include experiments and careful observation. The steps of the scientific method will be examined in detail later, but one of the most important aspects of this method is the testing of hypotheses by means of repeatable experiments. A hypothesis is a suggested explanation for an event, which can be tested. Although using the scientific method is inherent to science, it is inadequate in determining what science is. This is because it is relatively easy to apply the scientific method to disciplines such as physics and chemistry, but when it. Q: What important aspect of the scientific method is a suggested explanation for an event, which can be tested? Choices: - scientific control - string theory - independent variable - hypothesis A:
A: hypothesis

Q: Answer the following question given this paragraph: In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule. Pollination must occur for fertilization to take place. Zygotes develop into embryos inside seeds, from which the next sporophyte generation grows. Q: What develops into embryos inside seeds, from which the next sporophyte generation grows? Choices: - secretions - buds - pupa - zygotes A:
A: zygotes
