Opiates type of psychoactive drug is used medically to block pain messages to the brain. It is given medically to treat the patient with extreme pain condition.
Opioids, sometimes known as narcotics, are drugs that doctors recommend to relieve severe or chronic pain. People with backaches and chronic headaches utilize them. Opioids bind to opioid receptors, which are proteins found on nerve cells in the brain, spinal cord, gut, and other areas of the body. When this occurs, the opioids stop the brain from receiving pain signals that are delivered from the body through the spinal cord. Opioids involve considerable dangers and can be extremely addictive even if they can successfully treat pain. When opioids are used to treat chronic pain over an extended length of time, the risk of addiction is particularly high.

what can you infer about autonomic nervous system?
Autonomic nervous system is a part of the peripheral nervous system that involves involuntary physiological processes.
It contains three anatomically distinct divisions - sympathetic, parasympathetic, and enteric. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system. Generally, the SNS and PNS motor pathways consist of a two-neuron series: a preganglionic neuron with a cell body in the CNS and a postganglionic neuron with a cell body in the periphery that innervates target tissues.
The enteric nervous system (ENS) is an extensive, web-like structure that is capable of functioning independently of the remainder of the nervous system. It contains over 100 million neurons of over 15 morphologies, greater than the sum of all other peripheral ganglia, and is chiefly responsible for the regulation of digestive processes.

the oxygenic pathway was a significant achievement in life. the oxygen comes from the photosynthesis cycle. specifically what event in photosynthesis provides the oxygen?
Plants make energy during photosynthesis by utilising sunlight, water, and carbon dioxide. As a byproduct of this process, oxygen gas is released.
The oxygen in the air is produced by the catalytic centre of the multi-subunit enzyme photosystem II, which is responsible for the energy oxidation of water (PSII). Which of the following circumstances contributed to the emergence of oxygenic photosynthesis? Energy sources used by photosynthetic organisms initially included ATP and NADPH. Light energy is used in oxygenic photosynthesis to convert water (H2O) absorbed by plant roots into CO2 and generate carbohydrates. In this process, the water is "oxidised," or loses electrons, while the CO2 is "reduction," or gains electrons. Carbohydrates are generated along with oxygen. The evolution of molecular oxygen occurs in photosynthetic organisms photosynthetic systems as a result of the splitting of Oxygen molecules in PSII. The consumption of O2 molecules, on the other hand, results from their reduction.

In the electron transporter chain, oxygen is essential for cellular respiration. It is the last electron acceptor in the electron transport chain, allowing electrons to flow down the chain and produce ATP (adenosine triphosphate).
Oxygen is essential for energy generation via a system known as the electron transport chain (ETC), which is a component of cellular respiration. The electron transport chain generates adenosine triphosphate, the primary source of cellular energy.
After being stripped of glucose, high-energy electrons are accepted by oxygen. Cellular respiration achieves two key tasks: (1) it breaks down glucose into smaller molecules, and (2) it harvests and stores the chemical energy generated in ATP molecules.
The oxygen we breathe in is utilized to convert glucose into carbon dioxide and water.

Then determine which of the four principles of natural selection has occurred (overproduction of offspring, adaptation, variation, and descent with modification) as well as what condition(s) drive natural selection. There are 2 pages! 1. Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves.
Natural selection will occur, and it will integrate the four natural selection principles.
What is Natural selection?As an evolutionary force, natural selection picks favorable alleles and raises their frequency in the population.
The four principles of natural selection are as follows:
1) Propagation
2) Succession
3) Variations in property
4)Changes in fitness
Natural selection is an evolutionary mechanism that favors genotypes with better fitness or aptitude. Natural selection favors the night worm over the daytime worm.
Here,
The four natural selection principles are as follows:
1) Reproduction: Natural selection must work on a population in order for it to reproduce and generate a new generation. As a result, the population will quickly be populated with people that possess characteristics that improve the species' chances of survival.
2) Inheritance: Inheritance works closely with reproduction because the genes of the parent combine to create the genes of the offspring.
3) Property variations: Natural selection can only be done within a population if the members of the population have different individual characteristics.
4) Fitness changes: Fitness is the ability of an organism to survive and reproduce as much as possible.

The triceps/biceps, hamstrings, and chest muscles have more fast-twitch fibres. However, whereas quadriceps and back muscles frequently exhibit a mix, shoulders, forearms, and calves are more slow-twitch.
What is twitch?One muscle fibre contracts during a twitch in response to a nervous system order (stimulus).
The lag phase refers to the interval between a motor neuron's activation and the onset of muscle contraction (sometimes called the latent phase).
Energy is used by slow-twitch muscles gradually and reasonably evenly, which prolongs its duration.
This enables them to work for an extended period of time without running out of energy. Fast-twitch muscles burn up a lot of energy rapidly before becoming exhausted and in need of a rest.
There are more fast-twitch fibres in the triceps/biceps, hamstrings, and chest muscles. However, shoulders, forearms, and calves are more slow-twitch, but quadriceps and back muscles typically display a mix.

if, in this model, the worm absorbs a sufficient amount of oxygen, are there any reasons why natural selection may prevent worms from growing arbitrarily large? explain.
Natural selection may prevent worms from growing arbitrarily large because Darwin’s theory of natural selection had three essential ingredients: variation, inheritance, and selection.
Only those who survive and reproduce will give rise to new variation, and survival and reproduction are determined by interactions with the environment. Given differences in fitness, “sieving” will tend to be non-random.
Given “limitless” variation, prevailing or recurring circumstances can make for accumulation of useful structure. This dependence on environment is what makes for claims about the powers of natural selection (force). An important underlying assumption is that a particular structure is not equally close to any other structure from a developmental point of view.
A mutation yielding an individual of the trait type Tn might be more probable with a Tn-1-parent than with a Tn-2-parent.v So, if the environment is such that Tn-1 replaces Tn-2, this increases the probability of a mutation producing Tn.
