Answer the following question given this paragraph: Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported. Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis. Q: What occurs when substances move from areas of lower to higher concentration or when very large molecules are transported? Choices: - migration - diffusion - passive transport - active transport A:
active transport

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
Ques: Answer the following question given this paragraph: Example 2.17 Determining Average Velocity from a Graph of Displacement versus Time: Jet Car Find the average velocity of the car whose position is graphed in Figure 2.47. Strategy The slope of a graph of x vs. t is average velocity, since slope equals rise over run. In this case, rise = change in displacement and run = change in time, so that. Q: In a displacement graph, the slope of the line is the average what? Choices: - direction - speed - time - velocity A:
Ans: velocity
(Q).
Answer the following question given this paragraph: In normal faults , the hanging wall drops down relative to the footwall. Normal faults are caused by tension that pulls the crust apart. This causes the hanging wall to slide down. Normal faults can build huge mountain ranges in regions experiencing tension ( Figure below ). Q: What makes up most of the inside of a plant? Choices: - star tissue - animal tissue - mitochondria - ground tissue A:
(A).
ground tissue
Ques:Answer the following question given this paragraph: Many circuits have switches to control the flow of current through the circuit. When the switch is turned on, the circuit is closed and current can flow through it. When the switch is turned off, the circuit is open and current cannot flow through it. Q: A switch in a circuit controls the flow of what, specifically, within the circuit? Choices: - pressure - resistance - density - current A:

Ans:current
Answer the following question given this paragraph: Hydrocarbons are extremely important to modern life. Their most important use is as fuels. Hydrocarbons are also used to manufacture many products including plastics. The main source of hydrocarbons is fossil fuels. Q: What is the main source of hydrocarbons? Choices: - photosynthesis - greenhouse gases - decomposers - fossil fuels A:
fossil fuels
