Answer:

Elbow. The radius articulates with the ulna in a synovial pivot joint. The radial head rotates within the annular ligament and radial notch on the ulna to produce pronation of the forearm. The radius and ulna also articulate distally in reverse to their articulation at the elbow to produce supination.

The foundation of health-related fitness is muscular strength.

<h3>What is health related to fitness?</h3>

The five aspects of fitness that are directly associated to health.

Flexibility
Cardiovascular fitness
Muscular strength
Muscular endurance
Body composition

The definition of health-related fitness includes workout routines you follow to try to maintain and improve your physical health.

Due to the importance of heart and lung health to overall wellness, cardiorespiratory endurance is regarded as the most crucial aspect of health-related exercise.

Without a strong heart, a person simply cannot live very long or very well.

Someone explain classical conditioning from Ivan Pavlovym to me please???????

pashok25 [27]

Answer:

Discovered by Russian physiologist Ivan Pavlov, classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.

Explanation:

The most important thing to remember is that classical conditioning involves automatic or reflexive responses, and not voluntary behavior (that's operant conditioning, and that is a different post). What does this mean? For one thing, that means that the only responses that can be elicited out of a classical conditioning paradigm are ones that rely on responses that are naturally made by the animal (or human) that is being trained. Also, it means that the response you hope to elicit must occur below the level of conscious awareness - for example, salivation, nausea, increased or decreased heartrate, pupil dilation or constriction, or even a reflexive motor response (such as recoiling from a painful stimulus). In other words, these sorts of responses are involuntary.

The basic classical conditioning procedure goes like this: a neutral stimulus is paired with an unconditional stimulus (UCS). The neutral stimulus can be anything, as long as it does not provoke any sort of response in the organism. On the other hand, the unconditional stimulus is something that reliably results in a natural response. For example, if you shine a light into a human eye, the pupil will automatically constrict (you can actually see this happen if you watch your eyes in a mirror as you turn on and off a light). Pavlov called this the "unconditional response." (UCR)

As soon as the neutral stimulus is presented with the UCS, it becomes a conditional stimulus (CS). If the CS and UCS always occur together, then the two stimuli would become associated over time. The response that was initially produced in response to the UCS would also be produced in response to the CS, even if it was presented alone. Pavlov called this the "conditional response." (CR)

To make this a bit more concrete, we'll use Pavlov's dogs as an example. Before learning took place, the dogs would reliably salivate (UCR) when given meat powder (UCS), but they gave no response to the ringing of a bell (neutral). Then Pavlov would always ring a bell just before he would present the dogs with some meat powder. Pretty soon, the dogs began to associate the sound of the bell with the impending presence of meat powder. As a result, they would begin to salivate (CR) as soon as they heard the bell (CS), even if it was not immediately followed by the meat powder (UCS). In other words, they learned that the bell was a reliable predictor of meat powder. In this way, Pavlov was able to elicit an involuntary, automatic, reflexive response to a previously neutral stimulus.

Correct Each row of the table below describes an aqueous solution at . The second column of the table shows the initial componen

VMariaS [17]

Based on the given table;

A is a basic solution; addition of HClO₄ makes pH lower.

B is a neutral solution; addition of KI make pH stay same.

C is an basic solution; addition of NaClO₄ makes pH stay same.

D is a neutral solution; addition of KOH makes pH higher.

<h3>What changes occur in the pH of the solutions?</h3>

The pH of a solution is a measure of the acidity or alkalinity of the solution.

Solutions of pH less than 7 are acidic solutions whereas solutions of pH greater than 7 are basic solutions. Solutions of pH 7 are neutral solutions.

Addition of acids to an acid solution, will decrease the pH, while addition of a base will increase the pH.

Conversely, addition of a base to an basic solution will increase its pH whereas, addition of an acid will decrease the pH of the solution.

Based on the given table;

A is initially a solution; addition of HClO₄, an acid will make pH lower.

B is a neutral solution, addition of a neutral salt such as KI will make pH stay same.

C is an basic solution. When NaClO₄ is added, pH will be same.

D is neutral. Add KOH, and pH will be higher.

In conclusion, pH of a solution is affected by addition of acids, salts or bases.

My triglycerides are 350. Can I have a heart attack?.

inysia [295]

Answer:

Levels of 151-200 mg/dL are considered borderline high, while those above 200 mg/dL are linked to a higher risk for heart attack and stroke. Fasting TG levels over 500mg/dL increases the risk for a serious condition called pancreatitis.
