The body has very efficient internal defenses which can remove any quantity of an unwanted substance.a. True
b. False

I believe the answer is: A. conditioned stimulus

The conversion is being done by pairing the neutral stimulus with a specific outcome. In pavlov experiment, this being done by blowing a whistle before giving the dogs their food.

In the beginning, the whistle is a neutral stimulus that does not give any effecy to the dog. But overtime, hearing the whistle make the dog automatically salivated. When this happen, the neutral stimulus has become a conditioned stimulus.

Answer:

Im sure its A, But ill check

Explanation:

Taking the test rn

Explanation:

community fitness is a group of people who are at one location and do various activities together i.e squats pushups jogging etc

Final answer:

A constructivist lesson plan for high school health on the benefits of regular exercise.

Explanation:

A constructivist lesson plan focuses on active learning and student engagement. In the context of health care, a lesson plan could be designed around understanding the benefits of regular exercise on overall health. Here is a step-by-step breakdown of the lesson plan:

1. Introduction: Begin by discussing the importance of physical activity and its impact on health.
2. Group Activity: Divide students into groups and assign them different types of exercises. Each group will research the benefits and precautions associated with their assigned exercise.
3. Presentation: Each group presents their findings to the class, discussing the benefits and potential risks.
4. Reflection: Have students reflect on the information shared and identify ways in which they can incorporate exercise into their daily routines for improved health.
5. Closure: Summarize the key takeaways from the lesson and emphasize the importance of regular physical activity for maintaining good health.

Answer:

Resting potential

Explanation:

Final answer:

Glial cells are not part of the nerve impulse reaction; they provide support and insulation in the nervous system. Resting potential, action potential, and threshold are all directly involved in the nerve impulse conduction.

Explanation:

The component that is NOT part of the nerve impulse reaction among the given options is Glial cells. The other options, such as resting potential, moving potential (commonly referred to as action potential), and threshold, are all directly involved in the generation and propagation of a nerve impulse.

Resting potential refers to the difference in electrical charge across the plasma membrane of a neuron when it is not actively transmitting a signal. It is sustained by the sodium-potassium pump which helps maintain the distinct concentrations of sodium (Na+) and potassium (K+) ions inside and outside the cell. When the neuron is stimulated and the threshold is reached, voltage-gated Na+ channels open, causing an action potential by reversing the electrical charge across the membrane, allowing the nerve impulse to propagate along the neuron.

Glial cells, such as astrocytes and oligodendrocytes as shown in Figure 35.8, are supportive cells in the nervous system. They provide structure, nutrition, insulation, and help with signal transmission by myelinating axons, but they do not participate in the actual electrical signal or impulse that characterizes neuron communication.
