Answer:
b slow the normal reuptake of excess serotonin from synapses in depression
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Although other neurotransmitters are involved in depression affection, alteration in serotonin levels is an important cause of the disease.
Affected people that express depression show an alteration of the normal serotonin levels in the interneuronal space. There is a noticeable decrease in molecule concentration due to an increase in its reuptake.
The substances used in the depression treatment belong to the SSRI group. SSRI means Serotonin Selective Recapture Inhibitor. It means that these substances inhibit the reuptake of serotonin that usually occurs in affected patients.
ISSR treats depression by enhancing serotonin levels and its transmission by blocking the reuptake in neurons. In this way, there is more serotonin available to improve communication between neurons.
ISSRs are selective because their principal target is the serotonin molecule and not the other neurotransmitters.
Natural selection can be defined as__. the evolution of a population of organisms a process in which changes in gene frequencies result from evolution the production of more offspring than can survive in a given environment a process in which organisms with certain inherited traits are more likely to survive and reproduce than individuals with other traits What did Darwin find in South America that suggested that the Andes mountains had been gradually lifted up over millions of years? bird fossils at the top of mountains in Argentina dinosaur bones in the Amazon basin marine snail fossils high up in the Andes mountains impressions of ocean waves at the top of a mountain Which of the following is a component of the fossil record? the distribution of murid rodents in Australia and Asia the similarity of the forelimbs of cats and bats molecular sequences bones of extinct whales The oldest known fossils are from about years ago. 3.5 billion 6,000 4.0 million 1.0 billion Homology is evidence of__. biogeography convergent evolution natural selection common ancestry Which of the following is a population? the termites infesting your house along with the microorganisms living in their guts all of the termites that have ever lived all organisms living in your house the termites infesting your house
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways.
Because of this variety, some people have characteristics that suit their surroundings more than others. An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
In contrast to "artificial selection," which refers to practises like purposeful cross-breeding and selection for qualities that are appealing to people, "natural selection" refers to the process of choosing organisms with particular traits that is entirely motivated by nature.

How does the DNA of the 2 sister chromatids of chromosomes compare?
The genetic sequences of sister chromatids are identical. Sister chromatids occur only after the S (synthesis) phase, when the DNA is replicated in preparation for mitosis or meiosis.
A sister chromatid is a pair of identical copies (chromatids) generated by chromosomal DNA replication, with both copies connected together by a shared centromere.
To put it another way, a sister chromatid is 'one-half' of a duplicated chromosome. A dyad is a pair of sister chromatids.
Because both sisters are the result of semi-conservative DNA replication and so have the same DNA sequence, suitable criteria to identify sister chromatids are not clear.

List the significant events of the Electron Transport Chain. Include which reactants and products are involved. Highlight what will be released as a product. Be sure to include where the process occurs in the mitochondria.
Answer:
The electron transport chain is a series of protein complexes and electron carriers that are located in the inner membrane of the mitochondria. These complexes and carriers are involved in the transfer of electrons from NADH and FADH2, produced during glycolysis and the Krebs cycle, to oxygen, the final electron acceptor. The energy released from this transfer is used to pump protons across the inner mitochondrial membrane, generating a proton gradient that drives the production of ATP.
The key events of the electron transport chain include the following:
The transfer of electrons from NADH to complex I, also known as NADH-ubiquinone oxidoreductase, by the enzyme NADH dehydrogenase. This complex consists of several protein subunits and a non-protein electron carrier called ubiquinone.
The transfer of electrons from complex I to complex II, also known as succinate-ubiquinone oxidoreductase or succinate dehydrogenase, by the enzyme ubiquinone. Complex II consists of several protein subunits and a non-protein electron carrier called ubiquinone.
The transfer of electrons from complex II to complex III, also known as ubiquinone-cytochrome c oxidoreductase or cytochrome bc1 complex, by the enzyme cytochrome b. Complex III consists of several protein subunits and two non-protein electron carriers called cytochromes c1 and c.
The transfer of electrons from complex III to complex IV, also known as cytochrome c oxidase or cytochrome aa3, by the enzyme cytochrome c. Complex IV consists of several protein subunits and two non-protein electron carriers called cytochromes a and a3.
The transfer of electrons from complex IV to oxygen by the enzyme cytochrome a3. Oxygen is the final electron acceptor in the electron transport chain.
As the electrons are transferred through the complexes of the electron transport chain, energy is released and used to pump protons across the inner mitochondrial membrane. This creates a proton gradient that drives the synthesis of ATP by the enzyme ATP synthase. The end products of the electron transport chain are water and ATP.

the ______ is fenestrated.
A hole in the tracheostomy tube's shaft that is above the curvature and, thus, above the cuff of a cuffed trach tube is known as a fenestration.
A fenestration's function is to enable airflow past the vocal cords and upward. A tracheostomy patient cannot create voice without airflow via the vocal cords. How a Voice is Produced has further details about voice production.
It is not necessary to have a fenestration in order to speak with a tracheostomy tube, although it will probably make speaking louder and easier. See Speaking with a Tracheostomy Tube for more details.
Although a fenestrated tube can greatly ease speaking for tracheostomy patients, it's crucial to realise that in order to fully benefit from the fenestration, you must also utilise a fenestrated inner cannula.

Body get the energy for reattaching a third phosphate to ADP, creating ATP usually from carbs.
Breaking down the food molecules releases the energy that was keeping them together, and the cell temporarily stores that released energy for the re-building process.
Each of these food kinds necessitates a distinct breakdown process, which we'll discuss later, but the purpose is the same: release the energy that kept those food molecules together so that it may be stored in a form that the cell can utilize later to construct what it needed. The cell contains a specific type of molecule called ATP for storing that energy.
Adenosine triphosphate (ATP) is a vital chemical found in all living organisms. Consider it the "energetic currency" of the cell. When a cell requires energy to complete a job, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate.
The energy that was holding that phosphate molecule is now free to accomplish work for the cell. When the cell has excess energy (from digesting food or, in the case of plants, from photosynthesis), it stores it by reattaching a free phosphate molecule to ADP and converting it back into ATP.
