What is a direct result of depolarizing the presynaptic membrane of an axon terminal?
Answers
When the presynaptic membrane of an axon terminal is depolarized, it induces the opening of voltage-gated calcium ion channels.
What is an Axon terminal?
An Axon terminal may be defined as a region that is typically found at the end of a neuron after the termination of axons. This region is a small, spherical, bouton-like structure. It is also known as terminal boutons.
Once the voltage-gated calcium ion channels open, it allows the movement of calcium ions inside the cell. This entry of calcium ions provokes the fusion of synaptic vesicles with the membrane and finally the liberation of neurotransmitter molecules into the empty space which is known as the synaptic cleft.
Therefore, the opening of the voltage-gated calcium ion channel is the possible result of depolarizing the presynaptic membrane of an axon terminal.

Gjabolla has been suffering from a terrible fear of lightning for some time now. Whenever there are storms in the weather forecast, she gets very upset and plans on spending the duration of that time in her basement. She has even called in sick to work to avoid going out during a bad thunderstorm. How long would these symptoms have to persist before a diagnosis of a specific phobia could be made?
Answers
Answer:
6 months
Explanation:
A phobia can be described as a condition in which a person faces severe anxiety for a certain event or object that he observes. The person might behave irrationally when he/she observes the fearful event or object. Although a person completely understands that he is behaving irrationally after encountering the problematic situation, however he cannot control himself at the time when he experiences the situation. Psychologists diagnose phobia when a person continuously fears a situation for more a period of six or more months.

Explain how a primary sensory neuron transmits information about the intensity of a stimulus to a secondary sensory neuron at a chemical synapse (i.e. explain temporal summation of postsynaptic potentials).
Answers
Answer:Information, in the form of nerve impulses, reaches the spinal cord through sensory neurons of the PNS. These impulses are transmitted to the brain through the interneurons of the spinal cord. ... The spinal cord is thus responsible for mediating all information flow between the body and the brain.

topographic symbols
contour interval
topographic interval
index topography
Answers
The items that are used to show elevation, relief and slope on a topographic map is
- contour lines
- index contours
- contour interval
The following information should be considered:
- Topographic maps are those that represent a detailed projection of the relief of a particular place.
- This type of map represent in a very elaborate and precise form the significant information so that it is possible to get to know an area geographically and to know whether the region has forests, springs, urban areas, slopes, plains, among other characteristics.

Answer:
- contour lines
- index contours
- contour interval
Explanation:
Topographic maps are those that show a detailed projection of the relief of a specific place. This type of map usually presents in a very detailed and precise form the necessary information so that it is possible to know an area geographically and to know if that region has forests, springs, urban areas, slopes, plains, among other characteristics. These maps allow it to be analyzed if a region has elevation, relief and inclination, for that, contour lines, contours of the index and contour interval are used to expose this information.
Skeletal muscle is _____. a. "voluntary" because its contraction is deliberate
b. classified as a subtype of cardiac muscle
c. also known as smooth muscle
d. "involuntary" muscle and its movement is not deliberate
e. made up of cells with a single nucleus
Answers
Answer: Option A
Voluntary because its contraction is delibrate
Explanation:
Skeletal muscles are voluntary muscles that are controlled by the somatic nervous system (SNS). They are mostly found in the muscles and are muscles that are attached to bones. Attachment to bones is done by tendons which is made up of many bundles of collagen fibers. Contraction of skeletal muscles are deliberate i.e. voluntary and they are also involved in movement.
Answer:
it should be A
Explanation:

Answers
Answer:a. make up the inner layers of connective tissue
Explanation:Epithelial cell are cell made up of inner connective tissues. This tissues helps in absorption of nourishment/ nutrient needed by the epithelial tissue.
They are arranged into sheet and joined to each other. This special properties aids it function.
Epithelial cell have modified surface structurally and through internal modifications this aids there ability for absorption and secretion of some glands such as liver, digestive tract and also act as barrier.
They form a sheet of cell called epithelia that serves as linning for body surfaces.
They can be classiified into three bases the shape on how the cells are packed;
Squamous epithelium- They are usually wider. They can be found in blood vessels
Cuboidal epithelium are almost similar in height and width
Columnar exceptionally are Tall and wide.
