NEW QUESTION # 99
A symbiotic relationship where one organism benefits and the other is neither helped nor harmed is referred to as
Answer: C
Explanation:
Commensalism is a type of symbiotic relationship in which one organism benefits while the other is unaffected. An example is barnacles attaching to whales, where the barnacles gain transportation and access to food, while the whale is neither helped nor harmed. Mutualism benefits both organisms, parasitism benefits one while harming the other, and predation involves one organism killing another for food. Understanding ecological relationships is a key topic on the NEX Science exam, and recognizing the differences between types of symbiosis is essential.

NEW QUESTION # 100
The graph displays a patient's systolic blood pressure taken daily from February 1 to May 2.
What is the apparent range of blood pressure over this period?
Answer: B
Explanation:
The range of a data set is calculated by subtracting the lowest value from the highest value. From the graph, the lowest systolic blood pressure reading appears to be about 125 mmHg, while the highest reading is about
185 mmHg. Subtracting gives: 185 # 125 = 60. Therefore, option B is correct. Option C represents a single high reading rather than a range. Options A and D underestimate the difference. NEX questions involving range require careful identification of extreme values on graphs, so it is important to examine the entire data set, not just the most common values.

NEW QUESTION # 101
Which neuron carries the impulse from a receptor to the central nervous system?
Answer: A
Explanation:
Sensory neurons, also known as afferent neurons, carry impulses from sensory receptors to the central nervous system (brain and spinal cord). These neurons transmit information such as touch, temperature, pain, and pressure. Motor (efferent) neurons carry impulses away from the CNS to muscles or glands. Association neurons, also called interneurons, connect sensory and motor neurons within the CNS. The NEX Science exam frequently tests neural pathways and directional flow of nerve impulses, making sensory neurons the correct answer for signals traveling from receptors to the CNS.
