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:
neurodevelopmental disorders
Answer the following question given this paragraph: Optical telescopes are designed to collect visible light. The two types of optical telescopes are reflecting telescopes and refracting telescopes. Q: What are the two types of optical telescopes? Choices: - reflecting and recapitulating - reflecting and layering - refracting and compound - reflecting and refracting A:
reflecting and refracting
Q: Answer the following question given this paragraph: The answer is actually "no. " A virus is essentially DNA or RNA surrounded by a coat of protein ( Figure below ). It is not made of a cell , and cannot maintain a stable internal environment ( homeostasis ). Recall that a cell is the basic unit of living organisms. So if a virus is not made of at least one cell, can it be living? Viruses also cannot reproduce on their ownthey need to infect a host cell to reproduce. So a virus is very different from any of the organisms that fall into the three domains of life. Q: A virus is essentially dna or rna surrounded by a coat of what? Choices: - acids - paint - organism - protein A:
A: protein
Question: Answer the following question given this paragraph: This sperm is ready to penetrate the membrane of this egg. Notice the difference in size of the sperm and egg. Why is the egg so much larger? The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes. Q: Which part of the reproductive process only contributes one set of chromosomes? Choices: - ovum - plasma - egg - sperm A:
Answer: sperm

Answer the following question given this paragraph: Figure 8.15 A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the lightharvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain discussed below. Q: In a photosystem, pigments in the light-harvesting complex pass light energy to two special molecules of what in the reaction center? Choices: - calcium - carbonate - nutrient - chlorophyll A:
**Answer**
chlorophyll
Q: Answer the following question given this paragraph: An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Q: What device uses electromagnetic induction to change the voltage of electric current? Choices: - electric combustion - electric conductor - convection device - electric transformer A:
A: electric transformer
