Once a cell fires, the part of a neuron that transmits information to another location is the axon.
When a neuron fires, it generates an electrical impulse known as an action potential that travels along its axon towards the axon terminal. The axon terminal is the part of the neuron that transmits information to another location, such as another neuron or a muscle cell.
At the axon terminal, the electrical signal is converted into a chemical signal in the form of neurotransmitters. These are chemical messengers that can cross the synaptic cleft, a small gap between the axon terminal of one neuron & the dendrites of another neuron or a muscle cell.
Neurotransmitters are stored in vesicles in the axon terminal. When an action potential reaches the terminal, it causes calcium ions to enter the terminal, triggering the release of neurotransmitters into the synaptic cleft.
The neurotransmitters diffuse across the cleft & bind to receptors on the receiving neuron or muscle cell, causing a change in its electrical activity.

when bacteria establish themselves in or on a host without causing an infection, this is known as
When bacteria establish themselves in or on a host without causing an infection, this is known as colonization.
Colonization occurs when bacteria are present in a specific area of the body but do not cause any harm or symptoms to the host. This is common in areas such as the skin, respiratory tract, and gastrointestinal tract, where bacteria can reside without causing any harm to the host.
However, colonization can sometimes lead to infections if the bacteria spread to other parts of the body or if the host's immune system becomes compromised. It is important to note that not all bacteria that colonize the body are harmful, and some may even be beneficial to the host by aiding in digestion or protecting against harmful bacteria. Regular hygiene practices, such as hand washing and maintaining a clean environment, can help prevent colonization from leading to infections.

.During a marathon which of the following hormones is least likely to be released by the runner?
A) epinephrine
B) antidiuretic hormone (ADH)
C) angiotensin II
D) atrial natriuretic peptide (ANP)
During a marathon, the least likely hormone to be released by the runner is D) atrial natriuretic peptide (ANP).
ANP is primarily released by the heart's atrial cells when there is an increase in blood volume or pressure. Its main function is to lower blood pressure and volume by promoting vasodilation, increasing the excretion of sodium and water by the kidneys, and suppressing the renin-angiotensin-aldosterone system. In contrast, hormones like epinephrine (A), antidiuretic hormone (ADH) (B), and angiotensin II (C) are more likely to be released during a marathon. Epinephrine is a stress hormone released by the adrenal glands, which prepares the body for a fight-or-flight response by increasing heart rate, blood pressure, and energy supply. ADH, released by the pituitary gland, helps maintain the body's water balance by regulating urine concentration and preventing dehydration. Angiotensin II, part of the renin-angiotensin-aldosterone system, contributes to the regulation of blood pressure by causing vasoconstriction and promoting the release of aldosterone, which increases sodium and water reabsorption in the kidneys. In summary, ANP is the least likely hormone to be released during a marathon, as its primary role is to reduce blood pressure and volume, whereas the other listed hormones play a more direct role in supporting the body's physiological demands during intense physical activity.

leukocytes move through interstitial spaces using ______, a type of self-propulsion.
Answer:
ameboid motion
Explanation:
Leukocytes, also known as white blood cells, are an essential part of the immune system responsible for fighting off infections and foreign invaders. These cells move through interstitial spaces using amoeboid motion, a type of self-propulsion.
Amoeboid motion is a type of movement that allows cells to crawl through tissues and spaces. It is characterized by the formation of pseudopodia, which are temporary projections of the cell's membrane that extend in a certain direction, then contract, and pull the cell forward. This process is repeated continuously, allowing the cell to move in a particular direction.
Leukocytes use amoeboid motion to move through interstitial spaces, which are the spaces between cells in tissues. These spaces are often filled with extracellular fluid, which leukocytes can easily navigate using their flexible cytoplasm and pseudopodia. This movement allows them to migrate towards areas of infection or injury, where they can neutralize invading pathogens and promote tissue repair.

the change in foot structure of horses from ancestral species to modern species is indicative of:
The change in the foot structure of horses from ancestral species to modern species demonstrates the remarkable process of evolution, as these creatures adapted to new environments and selective pressures.
The transformation from a multi-toed foot to a monodactyl foot has equipped modern horses with the necessary speed, agility, and endurance to thrive in their current habitats. The change in the foot structure of horses from ancestral species to modern species is indicative of evolutionary adaptations that have occurred over millions of years to enhance their locomotion, speed, and survival. Early horse ancestors, such as Eohippus or Hyracotherium, had multiple toes (usually four) that provided stability and grip while navigating varied terrains, including forests and wetlands. As time passed, environmental conditions changed and grasslands began to dominate the landscape. Horses faced new challenges and selective pressures, such as the need for increased speed to escape predators and more efficient movement across vast open areas. The horse foot structure gradually evolved into the single-toed structure seen in modern horses, Equus ferus caballus, which features a large, strong hoof. This development is known as the monodactyl foot.
The hoof's structure distributes the horse's weight evenly and absorbs impact during high-speed running, providing both durability and resilience. Additionally, the loss of side toes reduced the overall weight of the leg, allowing for more efficient movement and increased speed. Concurrently, the bones in the horse's legs elongated, and the ankle and wrist joints became more elevated, further enhancing their running abilities.

if curl reforming is desired, make sure hair was not previously treated with which of the following?
If curl reforming is desired, make sure hair was not previously treated with a chemical relaxer.
Chemical relaxers are used to straighten curly or wavy hair by breaking down the protein bonds that give the hair its natural shape. Curl reforming, on the other hand, is a chemical process that adds curl or wave to straight hair. If the hair has already been treated with a relaxer, the protein bonds in the hair have already been altered, and adding more chemicals to the hair to create curls can cause damage and breakage.
It is important to ensure that the hair is in good condition and has not been previously treated with a relaxer before attempting to curl reform. A consultation with a professional stylist is recommended to determine if the hair is suitable for the desired treatment and to discuss any potential risks or damage that may occur.
