Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!
Explanation:
Shivering as a natural, involuntary response to generate heat is an example of maintaining homeostasis by regulating body temperature.
Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.
When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.
The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.
Hopes this helps happy early Christmas!!!! :D
Polar molecules (with +/- charges) are attracted to water molecules and are hydrophilic. Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic.
Answer:
it signifies delayed response to the victim, that there is no sign of any life threatening injury , but it is needed to check for any noticeable signs of external injuries.
Explanation:
Jump-start algorithm are generally used to sort children into categories based on the degree or extent of the injuries in multiple -causality situations.
it is applicable to children from infancy to age 8yrs,
It is divided into 4-categories called Triage categories,with certain 4- colors where each indicates the extent of severity of the child conditions represented with tags.
Thus Red- tag indicated need for urgent medical attention,because of life threatening injuries.
Yellow indicated although medical attention is needed, the injury is not life threatening. Intervention may be delayed for few hours.
Green-indicated minor injury, that is not so serious,medical intervention may be delayed for some days
Black indicated diseased or the injury is so severe that the life of the victim can not be saved with available resources.
