Answer: Anaesthesia blocks or impairs impulse transmission which helps patients not to feel pain during surgery
Explanation: . Local anesthesia affects the neural processes usually at the nodes of Ranvier by reducing the rate at which sodium ions(which are positive) flow through the membranes. Local anesthetics blocks sodium influx into the cell membranes ensuring that the minimum threshold for transmission is not reached thereby causing no pain.
General anesthesia on the other hand opens Chloride ions(which are negative ions) channel thereby allowing chloride to flow into the cell membranes causing hyperpolarization. As the negative ions increase, this shifts the membrane potential away from the minimum threshold thereby blocking the pain during surgery.
At the time when Sara felt no fear towards the buzzing sound of the bee, this means that the buzzing bee was a <u>neutral stimulus. </u>
<h3>What is a neutral stimulus?</h3>
This is a stimulus that a person has not developed an adverse reaction to as of yet but might still do so.
Sara had not developed an adverse reaction to bee buzzing sounds because she did not know that it meant she might be stung.

Answer:
<em>Gender identity is defined as a personal conception of oneself as male or female (or rarely, both or neither). This concept is intimately related to the concept of gender role, which is defined as the outward manifestations of personality that reflect the gender identity. Gender identity, in nearly all instances, is self-identified, as a result of a combination of inherent and extrinsic or environmental factors; gender role, on the other hand, is manifested within society by observable factors such as behavior and appearance. For example, if a person considers himself a male and is most comfortable referring to his personal gender in masculine terms, then his gender identity is male. However, his gender role is male only if he demonstrates typically male characteristics in behavior, dress, and/or mannerisms.</em>
