OK so basically you use a compound light microscope to observe specimen so if you were trying to find micro organisms that would be the one to choose.
Answer: The actions that results in the best chance of survival is (Start CPR, and use an AED if one is available).
Explanation:
First aid is a life saving procedures which are carried out in emergency situations by either a trained personnel or any available individual following a guideline. These life threatening emergency situations include:
--> when an individual stops breathing
--> severe bleeding of all types
--> Electric shock
When an individual stops breathing an immediate resuscitation is required. This is because if the brain is deprived of oxygen for more than about 4 minutes, permanent brain damage will occur. Therefore artificial respiration (ventilation) should be applied. This can be done following the Cardiopulmonary resuscitation (CPR) procedures and accompanied with an automated external defibrillator (AED) is available to achieve the best chance of survival.
Cardiopulmonary resuscitation (CPR) is a lifesaving procedure that involves the combination of chest compressions with artificial ventilation through the mouth for someone who is not breathing. This should be done first, if the individual is not responding, may be the heart is not beating due to a circulatory arrest, an automated external defibrillator (AED) should be used if available. This easy to use device delivers an electrical shock to the heart which enables it re-establish an effective rhythm.
Answer:
most will discover that three main ingredients are needed for clouds to form: moisture, condensation, and temperature. Evaporation and condensation are part of how a cloud forms
Answer:
As more and more time is spent on one activity, the opportunity cost of that activity in terms of other activities rises
Explanation:
The allocating scarce resources is done to increase the output for the well being of the nation. This resources allocation must be associated with the decision makings.
Time is the important scarce resource that constrain the human behavior. The achievement of the particular goal occur by the efficient use of the time. The humans have different capabilities and spending more time on single activity can increase the opportunity cost.
Thus, the correct answer is option (1).
Calcium is necessary for the development of bones and teeth, the transmission of nerve impulses, the contraction of muscles, blood coagulation, and blood pressure management.
Calcium D as fat soluble:
Vitamin D is a fat-soluble vitamin that is added to some foods, found naturally in a few, and sold as a dietary supplement. It is also known by the name "calciferol." Additionally, it is created internally when ultraviolet (UV) rays from sunshine strike the skin and start the production of vitamin D.
In addition to its ability to control processes like cell proliferation, immunological response, and glucose metabolism, vitamin D also reduces inflammation in the body . Vitamin D influences several genes that code for proteins that control cell division, differentiation, and apoptosis.
