Both heart attack and heart failure are serious cardiovascular conditions. A heart attack is blockage of blood flow to the heart and occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. The heart attack is acute and sudden and causes a lot of chest pain . Heart failure on the other hand occurs when the heart cannot circulate blood through the body and is a chronic progressive process. According these explanations the following statement is true: Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency. Correct answer: C
Schachter-Singer two-factor theory
Explanation:
A polygraph is a lie-detector test which uses certain devices and procedure to measure or record various physiological parameters like blood pressure, heart rate, respiratory rate, skin conductivity etc at the same time when the subjective person answers to a series of questions asked.
The principle is that a person’s or examinee’s physiological or clinical parameters like blood pressure or heart rate can accelerate, stay stable, or may even go down in response to the questions asked. Depending upon these changes, the examinee can be assessed whether he/she is telling a lie or truth about something asked.
The Schachter-Singer two-factor theory of emotions states that emotions are dependent on two factors – physiological arousal and cognitive label.
According to this, an environmental stimulus gives rise to a physiological reaction or arousal which then leads to cognitive appraisal of the emotion.
Thus the theory of polygraph is based on Schachter-Singer’s emotional theory.
Answer: Interval
Explanation: The measurement level of the data will be an interval level due to the following reasons ;
Temperature measurement recorded in Fahrenheit is quantitative in nature that is, it deals with quantity or numbers and not with category or level which is reffered to as qualitative. The measurement levels or scale avaliable for recording quantitative variable are the ratio and interval scale. However, difference between both scales lies in the existence of true zero in the measurement. In the ratio scale, True zero exists. However, in the interval scale, there is no true zero. As a value of zero doesn't mean that the measured variable does not exist. Therefore in temperature measurement using Celcius or Fahrenheit scale and also pH measurement, the interval scale is employed.
Answer:
it makes us beautiful and fresh
Explanation:
Falls are the leading cause of death when it comes to home accidents. They make up a third of all fatalities. The elderly are most affected by this type of accident. Fatalities aside, when an elderly person falls the associated problems are far more serious. While younger people may also suffer a broken bone, a broken bone is a far more serious problem for an older person in terms of healing.
Minimize The Risk
Staircases: Keep children safe from tumbling down steps by installing safety gates at both the bottom and top of staircases. Keep everyone safe by making sure the lighting is good and the handrails and steps are solid and well maintained. Elderly people with less mobility should consider installing stairlifts or consider moving to a home without stairs to avoid falls.
