what is an example of an open system​

Answers

Answer 1
An open system is a system that freely exchanges energy and matter with its surroundings. For instance, when you are boiling soup in an open saucepan on a stove, energy and matter are being transferred to the surroundings through steam. Putting a lid on the saucepan makes the saucepan a closed system.
Answer 2
A perfect example of an open system is a living organism such as a human being. We actively interact with our environment, which results in changes to both the environment and us.

explain five reasons why we need interdisciplinary connectivity approach in teaching physical education music and dance​

Answers

Answer:

Explanation:

“Movement activates the body's neural wiring, and thus the whole body becomes a learning instrument”

The term “movement” describes both internal and external action and encompasses every kind of motor behaviour, from the response of the whole body, to the gross and fine motor skills required to perform complex tasks . Movement occurs in the womb, for quite some time, before birth. In the prenatal environment, the mother's heartbeat may represent the first rhythmic experience.

Movement is the primary means of communication for children. Movement symbolizes their natural response to music and is vital to early childhood musical experience. Prior to language development, children use physical movement and sound to communicate with their surroundings. According to , children use movement to learn how to listen and interpret, respond, and explore. Movement activates and integrates connections in the brain, thus enhancing the learning process.

Active learning is promoted in many areas

Knowledge, behaviour, skills and the likelihood of success are being developed

The learning of relevant topics is maintained (Garcia et al., 1996), appliedand transferred to new conditions (Nichols, 1994).

For young children, movement is a simple learning tool that leads to a more integrated interaction with the subject (Werner & Burton, 1979) and enhances the learning of basic concepts such as shape, energy, space, time and the Critical Thinking.5. Motion is a way of self-expression and social interaction.

Motor activities stimulate and attract children and facilitate the linking of learning experiences to everyday life (Garcia et al, 1996).

When body and mind are actively involved, memory develops.

Answers

Answer:2.4

Explanation:

6 is more than 5 so round up

Rounding 2.367 to the nearest tenth results in 2.4. To round the number 2.367 to the nearest tenth, you need to look at the digit in the hundredths place, which is the second decimal digit (the "6" in this case).

If the digit in the hundredths place is 5 or greater, you round up the preceding digit (in the tenths place), and if the digit in the hundredths place is less than 5, you leave the preceding digit as it is.

In this case, the digit in the hundredths place is 6, which is greater than 5. So, you round up the digit in the tenths place, which is 7.

Name and explain the purpose of one law that protect citizen in gender based violence

Answers

Answer:

Explanation:

Gender based violence : name

explain: The phenomenon of gender-based violence is pervasive around the world,

experienced by some one in three women in their lifetimes. The elimination of such

violence has been increasingly recognized as a priority for the international

community.

The Sustainable Development Goals include a specific target to “eliminate all forms

of violence against all women and girls in the public and private spheres.”

2

A recent

special series of The Lancet on addressing violence against women provides an

excellent overview of the current evidence, and highlights that while growing

international recognition creates opportunities for renewed government

commitment, solutions will not be quick or easy.3

Legislation that criminalises violence against women codifies the rights of women to

live free of violence. Laws can play an important symbolic role, by indicating that such

behavior is socially unacceptable. The associated sanctions may serve a deterrence

function. Either or both levers may work in practice to reduce the incidence of

violence. It is of course difficult to observe which is more effective, though we do

have indirect evidence on both fronts. Legislation can also be responsive to victims,

by providing for protection and access to support services.

This paper investigates the potential and shortcomings of legislative action – and

how international and national laws can interact with norms in ways that can be

conducive to the reduction of the risk of violence. We argue that there has been

major progress in establishing the right of women to live free of violence in both

international and national law, especially over the past decade or so, with civil society

movements at the local and global levels playing a pivotal role. At the same time,

there is some way to go to address the underlying norms and behaviors associated

with violence.

The inflammatory response does not:_________ A. Replaces damaged tissue with healthy tissue B. Prevents the spread of disease to surrounding tissues C. Starts the repair process of the tissue D. Disposes of the cellular debris E. The inflammatory response does all of the above.

Answers

Answer:

D) Does not get rid of cellular debris

Explanation:

Hope that helped! :)

The inflammatory response does not disposes of the cellular debris. The correct option is D.

What is inflammatory response?

When tissues are harmed by infection, trauma, toxins, heat, or any other cause, the inflammatory response (also known as inflammation) takes place.

Chemicals like histamine, bradykinin, and prostaglandins are released by injured cells. These substances promote swelling by causing blood vessels to leak fluid into the tissues.

Inflammatory inducers (tissue damage or infection), inflammatory sensors (mast cells and macrophages), inflammatory mediators (cytokines, chemokines, etc.), and the tissues that are impacted are the four stages of the inflammatory response.

Depending on the kind of pathogen that is injected, various alternatives are available during each step.

Organic waste left over when a cell dies—a natural result of a cell life cycle—is referred to as "cell trash."

When healthy cells are damaged by harmful physical, chemical, viral, biological, nutritional, or immunological causes, they might degenerate into cell debris.

Thus, the correct option is D.

Explanation:

Bob weights about 30 pounds over weight and he has type 2 diabetes. He is not on medication for his diabetes but is trying to control his blood sugars with diet and exercise. He would like to shed pounds quickly with a low carbohydrate diet. The diet allows an unlimited amount of beef, chicken, and fish as well as limited fruits and vegetables. Breads, grains, and cereals are not allowed. Bob is thrilled with his initial rapid weight loss, but after a weigh or two, his weight loss starts to slow. He begins to feel tired and light-headed. He is having headaches and notices a funny smell on his breath. Explain why Bob is tired, is light-headed, and has headaches and an unusual odor on his breath. What dietary changes could you suggest to reduce these symptoms?

Answers

Answer:

Bob can add fresh herbal teas such as cloves, cinnamon, mint and fennel to his diet, as well as including a large intake of water during the day. Consume eggs and dark leafy vegetables.

Explanation:

The symptoms Bob is experiencing are due to the low consumption of carbohydrates and sugars in his diet. Although it seems that this diet is disadvantageous, Bob needs to continue with it in order to control diabetes, but some modifications can be made so that he has milder symptoms, while his body gets used to it.

It is important that he takes fresh herbal teas to control bad breath. Water will also help with this symptom, in addition to reducing dizziness and tiredness, which will also be reduced with the consumption of eggs and dark green leafy vegetables.

Explain the contribution of cholinergic system in controlling different levels of activities.

Answers

Answer:

The main neurotransmitter is acetylcholine. From a functional point of view, this system is related to: memory and learning, motivations, perceptions, attention, regulation of organic functions, motor functions and movement, and some pathologies such as Alzheimer's.

Explanation:

Acetylcholine is the substance responsible for the transmission of nerve impulses from preganglionic to postganglionic neurons, in the ganglia of the autonomic nervous system. At the level of the parasympathetic nervous system, it also mediates the transmission between the postganglionic neuron and the effector organ. In addition, it is the mediator of nerve transmission of the terminal motor plate. The cholinergic pathways project from the Meynert basal nuclei, located in the pale, to the cortex (mainly frontal and parietal), and to the thalamus, amygdala, and hippocampus. The cholinergic receptors are divided into nicotinic and muscarinic. Nicotinic receptors bind to ion channels, are faster and generally excitatory, are blocked by curare, and are stimulated by nicotine and acetylcholine. Muscarinic receptors bind to the G protein, are slower, are excitatory or inhibitory, are blocked by atropine and stimulated by muscarin, pilocarpine, and acetylcholine. Acetylcholine is also widely distributed in the brain and is a key neurotransmitter in the regulation of vigilance levels and in the operation of large areas of association. Acetylcholine has been considered a mediator of learning and memory processes in the central nervous system. It has been linked to cognitive processes such as attention and learning. At the neuroendocrine level, acetylcholine increases vasopressin secretion by stimulating the posterior lobe of the pituitary. It also decreases the secretion of prolactin from the posterior pituitary. At the parasympathetic level, it contributes to intervening in food intake and digestion, anabolic processes and physical rest, increases blood flow to the gastrointestinal tract, gastrointestinal muscle tone and gastrointestinal endocrine secretions. The heart rate decreases. At the sensory level, the cerebral cholinergic neurons form a large ascending system whose origin is in the brain stem and innervates large areas of the cerebral cortex and is probably identical to the reticular activating system, in addition to maintaining consciousness they seem to intervene in the transmission of visual information, both in the superior colliculus and in the occipital cortex.

Answer: The cholinergic system contributes to brain activities related to attention and higher-order cognitive processes.

Explanation:

The cholinergic system fundamental for cognitive functions, such as memory, selective attention, and even emotional processes. These memory processes require cholinergic activity over brain parts linked to memory retention and consolidation, including the cerebral cortex, and the amygdala.

While damage in the central cholinergic neurons weakens memory, the intensification of cholinergic synapses enhances cognitive processes.
