Q: A measure of how close a series of measurements are to one another is what? Read this paragraph and choose the correct option from the provided answers: precision: A measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Choices: - calculation - density - reflection - precision A:
precision

Q: What happens when development of nervous system is disturbed? Read this paragraph and choose the correct option from the provided answers: Neurodevelopmental Disorders Neurodevelopmental disorders occur when the development of the nervous system is disturbed. There are several different classes of neurodevelopmental disorders. Some, like Down Syndrome, cause intellectual deficits. Others specifically affect communication, learning, or the motor system. Some disorders like autism spectrum disorder and attention deficit/ hyperactivity disorder have complex symptoms. Autism Autism spectrum disorder (ASD) is a neurodevelopmental disorder. Its severity differs from person to person. Estimates for the prevalence of the disorder have changed rapidly in the past few decades. Current estimates suggest that one in 88 children will develop the disorder. ASD is four times more prevalent in males than females. Choices: - vascular disorders - muscular disorders - neurochemical disorders - neurodevelopmental disorders A:
neurodevelopmental disorders

Q: According to one of einstein's theory, while light consists of particles, it behaves like this. Read this paragraph and choose the correct option from the provided answers: After Einstein proposed his theory, evidence was discovered to support it. For example, scientists shone laser light through two slits in a barrier made of a material that blocked light. You can see the setup of this type of experiment in the Figure below . Using a special camera that was very sensitive to light, they took photos of the light that passed through the slits. The photos revealed tiny pinpoints of light passing through the double slits. This seemed to show that light consists of particles. However, if the camera was exposed to the light for a long time, the pinpoints accumulated in bands that resembled interfering waves. Therefore, the experiment showed that light seems to consist of particles that act like waves. Choices: - thermodynamics - tides - molecules - waves A:
waves

Q: What feature of the spine helps with flexibility and strength? Read this paragraph and choose the correct option from the provided answers: Curvatures of the Vertebral Column The adult vertebral column does not form a straight line, but instead has four curvatures along its length (see Figure 7.20). These curves increase the vertebral column's strength, flexibility, and ability to absorb shock. When the load on the spine is increased, by carrying a heavy backpack for example, the curvatures increase in depth (become more curved) to accommodate the extra weight. They then spring back when the weight is removed. The four adult curvatures are classified as either primary or secondary curvatures. Primary curves are retained from the original fetal curvature, while secondary curvatures develop after birth. Choices: - shape - angle - arrangement - curves A:
curves
