Answer the following question given this paragraph: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. A modern version is shown in Figure 2.7 "A Modern Periodic Table". Most periodic tables provide additional data (such as atomic mass) in a box that contains each element's symbol. The elements are listed in order of atomic number. Q: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their what? Choices: - size properties - liquid properties - acid properties - chemical properties A:
chemical properties
Q: Answer the following question given this paragraph: 36.5 | Vision By the end of this section, you will be able to: Explain how electromagnetic waves differs from sound waves Trace the path of light through the eye to the point of the optic nerve Explain tonic activity as it is manifested in photoreceptors in the retina Vision is the ability to detect light patterns from the outside environment and interpret them into images. Animals are bombarded with sensory information, and the sheer volume of visual information can be problematic. Fortunately, the visual systems of species have evolved to attend to the most-important stimuli. The importance of vision to humans is further substantiated by the fact that about one-third of the human cerebral cortex is dedicated to analyzing and perceiving visual information. Q: About one-third of the human cerebral cortex is dedicated to analyzing and perceiving information related to what sense? Choices: - hearing - touch - taste - vision A:
A: vision
Question: Answer the following question given this paragraph: Precision describes how close estimates are to one another. Estimates that are relatively close to one another are precise. Let's assume that ten different students made an estimate of the volume shown in Figure above , and the values were: 52.9, 52.8, 52.9, 52.9, 53.3, 52.0, 52.8, 52.9, 53.0, 52.8. We can determine how precise these data by analyzing how close they are to an average. The average could be the mean, median or mode. The most common understanding of the average is the mean. This value is calculated by adding up all the numbers and then dividing by the total number of values. Other terms that can refer to the average are the median and the mode. The median is the middle value in a numerically ordered list of numbers. The mode is the value that occurs most often in a set of numbers. If no number is repeated, there is no mode for the list. Here are the calculated averages:. Q: What term describes how close estimates are to one another? Choices: - precise - Distant - efficiency - precision A:
Answer: precision

Answer the following question given this paragraph: Figure 27.15 Hormone Levels in Ovarian and Menstrual Cycles The correlation of the hormone levels and their effects on the female reproductive system is shown in this timeline of the ovarian and menstrual cycles. The menstrual cycle begins at day one with the start of menses. Ovulation occurs around day 14 of a 28-day cycle, triggered by the LH surge. Q: What process occurs around day 14 of a 28-day menstrual cycle, triggered by the lh surge? Choices: - sedimentation - fertilization - menstruation - ovulation A:
(Answer)
ovulation
