The action potential causes information to be transmitted from the axon of the first neuron (presynaptic neuron) to the dendrites or cell body of the second neuron (postsynaptic neuron) by secretion of chemicals called neurotransmitters.
How do synaptic transmissions occur?Synapse is the junction between neurons where information gets exchanged.The axon of the presynaptic neuron does not actually touch the dendrites of the postsynaptic neuron and is separated from them by a space called the synaptic cleft. Stimulation of the presynaptic neuron to produce an action potential causes the release of neurotransmitters into the synaptic cleft.Neurotransmitters are stored in small vesicles located in knoblike structures on the axon tips.Most of the released neurotransmitters bind with molecules at the receptors on the dendrites of the postsynaptic neuron.The combination of the neurotransmitter molecules to receptor cell molecules in the postsynaptic cell membrane produces a change of potential in the postsynaptic cell membrane called the postsynaptic potential (PSP).Thus a signal is caused on a postsynaptic neuron.Learn more about neuron here:

What are two significant ways your skeletal system and your circulatory system support one another
Answer:The bone marrow within your bones form new red and white blood cells and removes dirty blood cells. After making these new blood cells, it sends them to the circulatory system
Explanation:
Some functions of the skeletal system are more readily observable than others. When you move you can feel how your bones support you, facilitate your movement, and protect the soft organs of your body. Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilages of your skeletal system compose the scaffold that supports the rest of your body. Without the skeletal system, you would be a limp mass of organs, muscle, and skin. Bones facilitate movement by serving as points of attachment for your muscles. Bones also protect internal organs from injury by covering or surrounding them.
In order for you to enjoy the smell of a flower, molecules called _______ from the flower must land on your olfactory epithelium, which lines the inside of the nose.
In order for you to enjoy the smell of a flower, molecules called Odorants from the flower must land on your olfactory epithelium, which lines the inside of the nose.
When a person breathes in air containing odor molecules, the molecules attach to receptors in the nose and send signals to the brain. Odorants interact with primary epithelium olfactory receptors. Olfactory receptors, a type of epithelial cell with cilia, are found in the olfactory epithelium. These receptors receive the sense of smell, which is then sent to the brain.The sensory neuron connected to the receptor is activated when an odorant connects with a receptor that detects it. Only olfactory stimulus directly communicates with the cerebral cortex; all other sensory information is sent through the thalamus.Additionally, it has been suggested that the nasal mucus plays a role in the process of emulsifying hydrophobic odorant molecules, delivering them to receptor sites.learn more about Odorants here: https://brainly.com/question/14477810

Decrease the kilovoltage peak(kVp) by 10%
Kilovoltage peak is referred to as kVp. This is the maximum voltage that the X-ray machine will produce during an exposure.
For instance, if 80 kVp is chosen, the maximum power of x-rays produced during this exposure is 80 kilovolts.
The degree of contrast is controlled by kVp means the radiographic contrast decreases as the kVp rises. Increasing kVp also increases the image's overall density (darkness).
Therefore it is best to decrease the kVp by 10% for the next radiograph as a relatively minor change in kVp can have a big impact on the image.

Cancer takes time to grow because it is the culmination of a series of genetic and genomic changes called Mutations that enable certain cells to divide more frequently than normal.
What Are Mutations?Changes to an organism's DNA sequence are referred to as mutations. Mutations can be the result of viral infection, exposure to mutagens, or mistakes in DNA replication during cell division. Somatic mutations—those that take place in body cells—cannot be passed on to progeny, whereas germline mutations—those that happen in eggs and sperm—can.Mutagens are environmental elements that trigger mutations. Radiation, substances, and infectious diseases are a few examples of mutagens. The nature of mutations may be spontaneous.TP53, a gene that generates a protein that inhibits the development of tumors, is the gene that is most frequently altered in all malignancies. In addition, this gene's germline mutations can result in Li-Fraumeni syndrome, a rare, inherited condition that increases the risk of getting some malignancies.

What is the replicated DNA sequence for GGC GAG AAT GAA ACT ATT TGT AGC
Answer:
ccgctcttactttgataaacatcg
The replicated DNA sequence for GGC GAG AAT GAA ACT ATT TGT AGC is the sequence CCG CTC TTA CTT TGA ATA AAC ATC.
The replicated DNA sequence for GGC GAG AAT GAA ACT ATT TGT AGC would be CCG CTC TTA CTT TGA ATA AAC ATC. During DNA replication, the double-stranded DNA unwinds and separates into two strands. Each original strand serves as a template for the synthesis of a complementary strand.
The nucleotide pairing rules dictate that guanine (G) pairs with cytosine (C), and adenine (A) pairs with thymine (T). Thus, GGC is paired with CCG, GAG with CTC, AAT with TTA, GAA with CTT, ACT with TGA, ATT with TAA, TGT with ACA, and AGC with TCG. This process ensures that the two resulting DNA molecules are identical to the original DNA molecule.

Match each type of migration or dispersal to the image of the species that follows it.
[passive dispersal] [one direction only] [daily movement] [one return journey]
Dispersion is the change in the distribution area of populations. Snail: Daily Movements. Seeds: Passive dispersal. Fishes: One return journey. Butterfly: One way only.
What is dispersion?Dispersion is the change of range or distribution area. It refers to the movement of individuals or populations from one place to another one.
Dispersion is the dissemination and distance of some individuals from others. Each individual is considered the dispersion unit, being able to have different mobile stages.
Dispersion ends by causing changes in the distribution area.
Dispersion events might be
Ecological processes → to avoid intraspecific competition for resources. It might involve daily or seasonal migration. Intra-area movements. Biogeographical processes → Involve the individual movement in a wider area. Extra-area movements.There are different types of dispersion,
Jump dispersion → one or a few individuals of the same generation are capable of evading a barrier and getting to a new area where they establish themselves. This is the case of dispersion to an island.Diffusion → A whole population, through many generations, can reach wider areas by exploring and expanding to new favorable regions.
Secular migration → Diffusion events in too many generations. Involves evolution and speciation.
In the exposed example, we can identify the followings,
Snail ⇒ Daily Movements ⇒ dispersion to avoid competitionSeeds ⇒ Passive dispersal ⇒ dispersion by wind to stablish in a new area and avoid competitionFishes ⇒ One return journey ⇒ seasonal migration to look for better conditions.
