Answer:
Opioid pain killers block synaptic transmission of nerve impulses by binding to opioid receptors.
Explanation:
Different types of pain medication have different mechanisms of action. These pain medications are broadly classified as:Non-opioid pain killers that include aspirin and ibuprofen. These work by inhibiting the enzymes responses for producing the pain signals at the site of injury or source of pain. These enzymes, known as COX-1 and COX-2 produce a chemical called prostaglandin. This hormone transmits the pain signals to the nervous system.Opioid pain killers, such as codeine, morphine and oxycodone, physically block the synaptic transmission of the pain signal. They bind to receptors known as opioid receptors. Opioid receptors are G-protein coupled receptors (GPCR). In cell signaling, GPCRs are receptors that activate/inhibit signaling pathways through activation/inhibition of adenylyl cyclase, an enzyme that producing cAMP, a second messenger that regulates the K+ and Ca+2 channels responsible for nerve impulse transmission. Opioid pain killers inhibit adenylyl cyclase consequently reducing cAMP production. This blocks Ca+2 channels and opens K+ channels in the neurons, thereby reducing neuron excitability and the release of neurotransmitters.3. Adjuvant pain killers are used to treat neuropathic pain i.e. pain due to injury of the nervous system.
With regard to metabolic reactions, what does it mean when someone says a molecule has been "reduced"
Example is conversion of NAD+ to NADH+ is an example of reduced in metabolism.
Explanation:
Oxidation and reduction or redox reaction means transfer of electron from one atom to another in a compound.
In photosynthesis and respiration redox reaction are seen.
The substance that gain the electrons in metabolic reaction is said to be reduced.
In respiration process oxygen is being reduced. The NAD+ accepts hydrogen ion and 2 e- to become NADH+H+. These are electron carriers.
The reactions can be seen in glycolysis, Kreb's cycle.

What are five factors that determine the velocity of a stream?
The velocity of a stream is influenced by the stream gradient, sediment size, discharge volume, channel geometry, and obstructions or channel roughness, which all contribute to the stream's overall flow characteristics.
Explanation:Factors Determining the Velocity of a Stream
Several factors contribute to the velocity of a stream, which is the speed at which water moves through a cross-section of the stream. Here are five key factors:
Stream Gradient: The slope or steepness of the stream's course affects velocity. A steeper gradient generally leads to a faster flowing stream.
Sediment Size: Large sediments on the stream bed offer more resistance compared to smaller particles, thus affecting the stream's velocity.
Discharge Volume: The amount of water passing through the stream also impacts its velocity. More discharge typically means higher velocity.
Channel Shape and Size: The geometry of the stream channel influences how water flows, with narrower or shallower channels often leading to faster flows.
Obstructions and Channel Roughness: Presence of vegetation, rocks, and variations in channel smoothness create friction, altering the velocity.
Different aspects such as ground-water movement, stream erosion, and deposition also play a role in water flow dynamics. Understanding these variables is essential for managing water resources and studying ecological systems.
How does starch react with iodine?
Answer:
When iodine and starch are dissolved together in water, gooey starch molecules instantly trap iodine ions close together to create a dark, blueish-black color. (Dripping liquid iodine onto a potato will turn it the same color, due to all of the spud's starch.)

How do slime molds get their food?
Answer:
Slime molds, decompose decaying matter. The animal-like protists must "eat" or ingest food.
Explanation:
Slime molds, being fungus-like protists, feed on decaying organic matter by moving slowly over it and engulfing it directly when nutrients are abundant and forming a collective slug to release spores when food is scarce.
How Slime Molds Obtain Food:
Slime molds are fungus-like protists that can be found in environments such as rotting logs and compost piles, where they feed on decaying organic matter. These organisms adjust their feeding behavior based on the availability of food. When nutrients are plentiful, cellular slime molds exist as individual amoeboid cells that absorb food by phagocytosis. However, during scarce food conditions, they form a collective mass, a behavior exemplified by the dog vomit slime mold, which glides along on secretions to engulf food.
More specifically, when food resources are depleted, the independent amoeboid cells conglomerate into a slug-like structure. Within this slug, certain cells create a 2-3 millimeter stalk, sacrificing themselves in the process. Others form a fruiting body that releases haploid spores. These spores then have the opportunity to germinate in moist environments, potentially starting the cycle over again. A typical genus representing cellular slime molds is Dictyostelium, generally found in damp forest soil.

Your employer let’s you know that the safety data sheets are located on an computer in his office. Does this comply with employer responsibilities?
Yes, having the Safety Data Sheets (SDS) located on a computer in the employer's office can comply with OSHA requirements as long as employees have easy and immediate access to the information during their work shift.
Under the Occupational Safety and Health Administration (OSHA) guidelines, employers have the responsibility to provide their workers with a safe workplace that has no serious hazards, and to inform workers about chemical hazards through training and methods like chemical information sheets and Safety Data Sheets (SDS). An SDS is a detailed document that provides information about handling, storing, and disposing of chemicals safely. If these SDSs are located on a computer in the employer's office, it can comply with OSHA's requirements, provided that employees have easy, immediate access during their work shift. This access should not be hindered by barriers such as locked doors or needing special permissions, which could delay the retrieval of vital safety information.
The SDS must be readily available and not just during an emergency; workers should also be trained on how to access and interpret the information. The aim is to ensure that every employee comprehends the safety and health hazards of the chemicals and processes they work with to protect themselves, their colleagues, and the surrounding community. Hence, while having SDS on a computer is acceptable, the ease of access and proper training on its use are both critical compliance aspects.
Employers must provide safety data sheets to employees to ensure workplace safety and compliance with OSHA standards in order to fulfill his responsibilities as an employer.
Employers have certain responsibilities under the Occupational Safety and Health Administration (OSHA) to ensure a safe working environment. One of these responsibilities is to inform workers about chemical hazards. This can be done through various methods including training, labels, and providing access to Safety Data Sheets (SDS). According to OSHA requirements, an employer is supposed to make SDS readily available to employees when they are in their work area(s). Therefore, having the sheets only on a computer in the employer's office does not seem to comply unless workers have immediate and unimpeded access to that computer at all times during their work shift.
Safety Data Sheets contain critical information on handling chemicals safely, potential dangers, and procedures for emergencies. Employers must also provide adequate training in understanding and using these data sheets effectively. This all forms part of an employer's obligation to minimize health risks in the workplace, which includes making employees aware of hazards and ensuring they understand the risks associated with their job, particularly when working with hazardous materials.
A subatomic particle is removed from an atom to form an ion. A student wants to draw a
diagram of this process. From which part of the atom should the student show the subatomic
particle being removed?
A. from the nucleus of the atom
B. from the inner part of the atom
C. from the innermost energy level of the atom
D. from the outermost energy level of the atom
Answer:
The part of the atom from which a subatomic particle is being removed, to become an ion, and that the student should show is from the outermost energy level of the atom (option D).
Explanation:
Ions are atoms with an electric charge, caused by the gain or loss of electrons. The most external atomic orbital, or energy level, is the one that has the property to acquire or lose electrons so that an atom becomes an ion.
Whereas an electron has a negative charge, two things can happen:
When a given atom gains electrons in its outermost energy level, it acquires a negative charge, and is called an anion. Cations are atoms that lose electrons from the external orbital.In this case, the student must make a scheme that shows the subatomic particle -electron- the atom is losing comes from its outermost orbital.

For a future settlement on the moon, about how long will each period of daylight for the settlers last?
The day on the Moon for any future settlers will last roughly around 29.5 days.
Explanation:
The Moon, as all the space objects that are not bright themselves, have day and night. Every space body though has its own specific duration of the day, and that depends on the speed of rotation around its axis, as well as the position of the other space bodies and do they interfere in any manner. In the case of the Moon, it rotates around its own axis, but also around the Earth, and together with the Earth around the Sun.
One Moon day, if we take its rotation around its axis, lasts 27.3 Earth days. The rotation around the Sun though, and the interference of the Earth actually prolong the day on the Moon, and it is 29.5 Earth days. This mean that any future settlers on the Moon will have a day lasting almost as a whole month on Earth, and that can prove to be a big problem, as such drastic difference can cause lot of psychological and physical problems at organisms evolved for a totally different patterns of day and night.

Two types of stressors that learners are likely to experience in a post school destination as a college or university or the workplace
Answer:
financial stress and family stress
Explanation:
When learners go to college or a university, their family expects a lot from them especially when the parents are the ones who brought the learner to study. This causes stress on the learners. Choosing the major can also be stressful, especially when the family intercedes in the learner's decision. This also creates a financial burden on the learner, especially when the learner supports himself. So, he has to balance studying while working. If he has a scholarship, he has to maintain his grades in order to keep up.
In the same way, a person who goes to the workplace is also expected by his family to provide them financially. This creates a financial stress on his end. Besides this, he is also expected to make commitments especially when he has children. He needs to balance working while taking care of his kids and attending to their needs at home and in school. This is how family stress can affect him.
Final answer:
In a post-school destination such as college, university, or the workplace, learners may encounter various stressors that can affect their well-being and performance. Two types of stressors commonly experienced in these environments include:
Explanation:
Academic or Workload Stress:
Academic stressors in college or university settings can include heavy workloads, challenging assignments, exams, and academic pressure to perform well.
Workplace stressors may involve high workloads, tight deadlines, demanding projects, and the pressure to meet job expectations and deliver results.
These stressors can lead to feelings of overwhelm, anxiety, and pressure to succeed academically or professionally.
Social or Interpersonal Stress:
Social stressors in college or university settings may include difficulties in forming social connections, homesickness, conflicts with roommates or classmates, and feeling socially isolated.
Workplace stressors may involve interpersonal conflicts with colleagues or supervisors, difficulties in communication, workplace harassment or discrimination, and feeling disconnected from the workplace culture.
These stressors can impact individuals' sense of belonging, self-esteem, and overall emotional well-being.
Both academic/workload stress and social/interpersonal stress can have significant effects on learners' mental health, physical health, and academic or professional performance. Educational institutions and workplaces need to provide adequate support systems, resources, and strategies to help learners effectively cope with and manage these stressors. This may include access to counseling services, stress management workshops, mentorship programs, and creating a supportive and inclusive environment that promotes well-being and resilience.

D. How large is the gene pool for a given organism?
SUBMIT
Answer:
The correct option is C) How does allele frequency change between generations?
Explanation:
Hardy and Weinberg brought forward the Hardy- Weinberg theorem or principle to explain that the allele frequencies in a population change due to certain evolutionary events. If these events do not take place, then the allele frequencies of a population will remain the same. Their theorem explains how evolutionary conditions such as mutations, genetic drift, natural selection cause the allele frequency to change in generations of a population. Hence, option C is correct.
a mutation in a triplet code that ends up coding for the same amino acid is referred to as a silent mutation. in what sense is it silent?
A silent mutation is a change in the DNA sequence that does not alter the amino acid sequence of a protein, maintaining the protein's functionality. This occurs due to the genetic code's redundancy, where various codons can encode the same amino acid. These mutations are undetectable without genetic sequencing.
Explanation:A silent mutation occurs when a change in the nucleotide sequence of DNA results in a new codon, but that codon still encodes the same amino acid. This redundancy in the genetic code allows for such mutations to be "silent," as they do not alter the amino acid sequence of the protein being produced. Hence, the mutation is considered silent in the sense that it has no observable effect on the protein's function or the organism's phenotype.
Because most amino acids are encoded by multiple codons, a change, particularly in the third base of a codon, often does not change the encoded amino acid. For instance, if the TCT codon for serine is mutated to TCC, TCA, or TCG, serine is still encoded, making the mutation silent. Such mutations are only detectable through sequencing of the gene or its mRNA, as they cause no change in the protein product.
waste products in the blood are filtered out by the kidneys. In the past, kidney failures also led to death because of the buildup of poisonous waste in the blood. Today, however, doctors use dialysis machines to filter wastes out of the blood. Dialysis machines use artificial membranes. Are the membranes and a dialysis machine permeable or selectively permeable? Explain.
The membranes of dialysis machine are semi permeable membrane.
Explanation:Dailysis is the process of artificial separation of blood from the waste products and excretory substances. This process uses the process of osmotic separation of the blood from the excretory substances by using a fluid which also contains the materials of blood but in small amounts to prepare a osmotic gradient through which when the blood passes, can filter it off. The membrane separating the blood from the fluid is a semi permeable membrane which allows the water to go out along with urea and other excretory products slowly as the blood passes through Dyalysis machine.
