Answer the following question given this paragraph: Chapter 7 The Periodic Table and Periodic Trends In , we presented the contemporary quantum mechanical model of the atom. In using this model to describe the electronic structures of the elements in order of increasing atomic number, we saw that periodic similarities in electron configuration correlate with periodic similarities in properties, which is the basis for the structure of the periodic table. For example, the noble gases have what is often called filled or closed-shell valence electron configurations. These closed shells are actually filled s and psubshells with a total of eight electrons, which are called octets; helium is an exception, with a closed 1s shell that has only two electrons. Because of their filled valence shells, the noble gases are generally unreactive. In contrast, the alkali metals have a single valence electron outside a closed shell and readily lose this electron to elements that require electrons to achieve an octet, such as the halogens. Thus because of their periodic similarities in electron configuration, atoms in the same column of the periodic table tend to form compounds with the same oxidation states and stoichiometries. ended with the observation that, because all the elements in a column have the same valence electron configuration, the periodic table can be used to find the electron configuration of most of the elements at a glance. Q: What do halogens require electrons to achieve? Choices: - coupling - formation - fusion - octet A:
octet
Answer the following question given this paragraph: Laboratory testing has come to the local drug store or grocery store because of developments in chemistry. You can test your blood glucose using a simple portable device that runs a chemical test on the blood sample and tells you how much glucose is present, allowing a diabetic patient to regulate how much insulin to administer (chemistry is also used to produce the insulin and the disposable syringe that administers the drug). Q: Tests for levels of what in blood allow a diabetic patient to regulate how much insulin to administer? Choices: - alcohol - chloride - protein - glucose A:
glucose
Q: Answer the following question given this paragraph: Q: Asexual reproduction in plants is typically an extension of the capacity for what? Choices: - extracellular growth - substrate growth - blooming growth - indeterminate growth A:
A: indeterminate growth
Question: Answer the following question given this paragraph: Nuclear energy is produced by splitting the nuclei of radioactive uranium. This doesn't release air pollution or carbon dioxide, but it does produce dangerous radioactive wastes. Q: What type of energy occurs by splitting the nuclei of radioactive uranium? Choices: - microwave - atomic - kinetic - nuclear A:
Answer: nuclear

Answer the following question given this paragraph: Creep is the very slow movement of rock and soil down a hillside. Creep occurs so slowly you can't see it happening. You can only see the effects of creep after years of movement. This is illustrated in Figure below . The slowly moving ground causes trees, fence posts, and other structures on the surface to tilt downhill. Q: What is the very slow movement of rock and soil down a hillside? Choices: - landslide - evaporate - drop - creep A:
**Answer**
creep

Answer the following question given this paragraph: 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. Q: What happens when development of nervous system is disturbed? Choices: - vascular disorders - muscular disorders - neurochemical disorders - neurodevelopmental disorders A:
(Answer)
neurodevelopmental disorders
