Answer:
severe diarrhoeal diseases are among the leading causes of mortality in infants and young children in many developing countries like Nigeria and other Africa countries. In most cases, death is caused by dehydration.
During this diarrhoea there is an increased loss of water and electrolytes (sodium, chloride, potassium, and bicarbonate) in the liquid stool. Water and electrolytes are also lost through vomit, sweat, urine and breathing. Dehydration occurs when these losses are not replaced adequately and a deficit of water and electrolytes develops
If the body loses a substantial amount of fluids and salts and they are not quickly replaced; for example: by drinking, the body starts to "dry up" or get dehydrated. Severe dehydration could cause death.
Answer:
When a warmer air mass travels over colder ground, the bottom layer of air cools and, because of its high density, is trapped near the ground. In general, cold air masses tend to flow toward the equator and warm air masses tend to flow toward the poles. This brings heat to cold areas and cools down areas that are warm
Answer:
Concentric contraction.
Explanation:
Concentric contraction is a type of contraction that the muscles in arms experiencing when an individual lifting 24 bottles of water up the stairs. A concentric contraction is a type of muscle activation that creates tension on your muscle as it shortens. As your muscle shortens, it produces enough force to move an object in the upward direction. In weight training we can easily see concentric movement.
