Answer:
Neurons ARE NOT connected physically and communicate with each other at the SYNAPSEExplanation:
ANSWER: "ARE NOT" AND "SYNAPSE"Some neurons release neurotransmitter which affects neighboring cells, as well as themselves. this is an example of what type of signaling? choose any that apply.
A chemical secreted by one cell interacts with target cells nearby in paracrine signalling. The way neurotransmitters move signals between nerve cells at a synapse serves as an illustration.
After being produced, where are neurotransmitters kept?The terminal produces and stores small molecule neurotransmitters for quick release. Because they must be carried from the cell body to the terminal after being generated there, neuropeptides may release more slowly.
Small "packages" called vesicles are used to hold neurotransmitter molecules (see the picture on the right). When the vesicles containing neurotransmitters "fuse" with the membrane of the axon terminal, the neurotransmitter is released from the axon terminal and spills into the synaptic cleft

how ocean temperature affects the climate of an area
Answer:
Water's High Specific Heat Capacity
Explanation:
Water is able to absorb large amounts of heat with little to no change in temperature for itself. Therefore, when warm air flows over the ocean, the water absorbs the heat from the air and releases cool air instead. This allows coastal environments to be cooler than other areas.
Approximately how many atoms thick is a cell membrane, assuming all atoms there average about twice the size of a hydrogen atom?.
There are around 50 atoms in the cell membrane.
Knowing that the thickness of a cell membrane is somewhere between 7.5 and 10 nm will allow you to divide 7.5 and 10 by 0.2 nm, where 1 nm equals 1*109 m.
The cell membrane is roughly 37.5 and 50 atoms thick, according to the two answers of 47.5 and 50.
A hydrogen has a diameter of 10^ -10 m. A cell membrane has a 10^8 m thickness.
The formulae of thickness in terms of number of atoms = d /2 × D
Here the (d) = the diameter of membrane
The (D) = The diameter of hydrogen atom
The diameter of hydrogen atom = 10^-10 m
The thickness of membrane = 10^8 m
by substituting these value in above formulae
The number of atoms = 10^8 /2 × 10 ^−10 m
= 50 atoms
Consequently, the thickness of a cell membrane is equivalent to 50 atoms' total thickness.

Vasoconstriction is caused by ______ stimulation of vascular smooth muscle and ______ stimulation of vascular smooth muscle causes vasodilation.
Vasoconstriction is caused by sympathetic stimulation of vascular smooth muscle and parasympathetic stimulation of vascular smooth muscle causes vasodilation.
The narrowing (constriction) of blood arteries by tiny muscles in their walls is known as vasoconstriction. Blood flow is delayed or halted as blood vessels close. Vasoconstriction can range from mild to severe. It might be brought on by a sickness, medication, or psychological issues.Norepinephrine's interaction with postsynaptic -adrenergic receptors is the main mechanism by which sympathetic innervation of the peripheral vasculature promotes vasoconstriction. The majority of the body's blood arteries lack parasympathetic innervation. However, salivary glands, gastrointestinal glands, and vaginal erectile tissue are all innervated by parasympathetic neurons, which results in vasodilation. The parasympathetic division causes the body to go into "rest or digest" mode, typically lowering blood pressure and heart rate.Blood arteries often expand in response to parasympathetic stimulation, increasing blood flow but decreasing pressure.learn more about Vasoconstriction here: https://brainly.com/question/4359984

Dr. Collins built and designed his instrument based on facts—the recognized concussion symptoms. He needed to learn more about how concussions affect the brain and how people react to cognitive activities. He became aware of a weakness in the way concussions are currently handled. Many athletes don't treat the injury properly or put off getting help, which might have long-term negative effects. The latest device from Dr. Collins both looks for potential injuries and keeps track of healing. Thus, it meets a demand for concussion treatment.

If the connection between the hypothalamus and pituitary were severed, damaging the neurons, the secretion of which type of chemical messenger (signal) would most directly be affected?
If the connection between the hypothalamus and pituitary gland were severed, the releasing hormone would directly be affected.
Releasing hormones are the peptide hormones secreted by the hypothalamus gland to stimulate the pituitary gland. In response to releasing hormones, the pituitary gland releases other hormones like gonadotropin, ACTH, and TSH.
The four types of releasing hormones released by the hypothalamus include:
1. Gonadotropin-releasing hormone (GnRH)
It stimulates the release of follicle-stimulating hormone (FSH) and Luteinizing hormone (LH).
2. Thyrotropin-releasing hormone (TRH)
It stimulates the release of thyroid-stimulating hormone (TSH) and prolactin from the anterior pituitary gland.
3. Growth hormone-releasing hormone (GHRH)
It stimulates the release of growth hormone from the anterior pituitary gland.
4. Corticotropin-releasing hormone (CRH)
It stimulates the release of adrenocorticotropic hormone from the anterior pituitary.
If the neurons connecting the hypothalamus and pituitary gland are damaged, the releasing hormones would be affected. Consequently, the secretion of all of the above hormones would be affected.

Why do st. george, ut and salt lake city, ut have different climates?
Salt Lake City seems to be in a distinct state than southern Utah and the majority of the area east of the Wasatch.
In the vicinity of Salt Lake, several quite different geological regions are combined, so if you drive a few hours in any direction, you'll be in a very different region. For instance, if you travel east to Vernal, you'll think you're in a St. George suburb in the far southwest of the state. Even though St. George is over two hours away from Las Vegas, it is essentially a satellite of that city. It is located in a stunning red rock region with fields of black lava stone surrounding dormant volcanoes, canyons, arches, and palm trees. Geologically speaking, rather than merely politically, it seems like another planet. Culturally, anyone from Utah will feel at home in St. George, if they can endure the heat. It is still a very LDS town, but it is still managed by a small group of old-guard families who came here at Brigham Young's request nearly fifty years ago.

When a big fish swims into an oncoming smaller fish and swallows it, the momentum of the two-fish system _______.
When a big fish swims into an oncoming smaller fish and swallows it, the momentum of the two-fish system remains the same.
In this case, the Law of conservation of momentum principle is used as when a big fish swims into a smaller fish and also swallows it, then there will be no change in the system as the momentum of the two-fish system remains the same.
But when the momentum of the big fish exists in the same condition but since the final momentum is to be true, there arises a combined mass of the big fish as well as the small fish, whereas the case of speed must be reduced.
The Law of conservation of momentum is important as it states that the total momentum that occurred in the initial state of the system remains the same as the momentum that exists in the final state of the system. This conservation principle helps to determine the initial and final velocity of a system that undergoes collision. This collision can be either elastic or inelastic.

Which organism from kingdom protista is most closely related to animals?
a) paramecium spp.
b) choanoflagellates diatoms
c) red algae
d) amoeba spp.
Choanoflagellates diatoms from kingdom Protista is most closely related to animals.
The choanoflagellates are a class of unicellular and colonial flagellate eukaryotes that live in free-living environments and are thought to be the closest living relatives of animals. Choanoflagellates are collared flagellates; at the base of each flagellum, they have a funnel-shaped collar of intertwined microvilli.The Choanoflagellates are not a varied group of protists, with only 150 species in total. The name "collar-flagellates" comes from the ring of densely grouped microvilli, or thin fingerlike projections, that surrounds the single flagellum by which choanoflagellates both move and take in food. They are tiny single-celled protists that can be found in both freshwater and ocean environments. The collar appears as a single transparent unit in light microscopy because the microvilli are so closely packed, as shown in these illustrations.Therefore, option (b) is correct.
