Which structure of the nervous system carries action potential in the direction of a synapse?
Cell body
Axon
Neuron
Myelin
Correct Answer : B
Axons carry action potential in the direction of synapses. Axons are the long, fiber-like structures that carry information from neurons. Electrical impulses travel along the body of the axons, some of which are up to a foot long.
A neuron is a type of cell that is responsible for sending information throughout the body. There are several types of neurons, including muscle neurons, which respond to instructions for movement; sensory neurons, which transmit information about the external world; and interneurons, which relay messages between neurons. Myelin is a fat that coats the nerves and ensures the accurate transmission of information in the nervous system.

Explanation
The evidence says that every child in a certain family has been diagnosed with autism spectrum disorder (ASD). All of these children have genetic commonalities. Therefore, ASD may be genetic.
The evidence does not mention whether the children died from ASD. Therefore, no conclusion can be drawn that ASD may be lethal. Furthermore, the sample size of the evidence is much too small to suggest that ASD is related to traditional nuclear family structures.

Correct Answer is A
Explanation
Since only 2 out of the initial 16 plants survived the whole month, it would be reasonable to test variables that were shared by all the plants. As such, the amount of liquid the plants need would be a good follow-up experiment. It is not specified as to which plants survived, so there is not enough information to think that testing the impact of salt is warranted. Additionally, since almost all the plants died, it is not reasonable to assume that a combination of the solutions would have an impact.
Correct Answer is A
Explanation
In a scientific experiment, the dependent variable is the condition that is being tested and measured. The independent variable is the condition that is being changed or controlled. In this example, the amount of salt is varied, and the boiling point of water is measured. Therefore, the independent variable is the amount of salt, and the dependent variable is the temperature at which the water bolls.
