Answer:
Cloud
Explanation:
Clouds forms when invisible water vapour from the earth rises and turns to visible water droplets. This is caused by radiation of the sun on the earth surface, causing evaporation from the earth and is taken up the sky forming a cloud. It is also known that the more water vapour condenses into droplets, the greater amount of cloud that id formed.
Answer:
K+ ion concentration is high inside the cell under resting membrane potential.
Explanation:
Neurons generates electrical signals across its membrane called the resting potential. The resting potential is determined by the concentration gradient of ions and membrane permeability to ions.Therefore, in a resting neuron there are a concentrations gradient for Na+ and K+ ions across the membrane. The movement of ions towards the gradient through channels . The ions' movement create a resting potential by separating its charge.
The West Nile virus is a fatal neurological disease in humans.
Answer:
Approximately 24 hours.
Explanation:
Our body has two complementary ways of energy storage. It can store energy as:
Glycogen in the liver.
Body fat.
Glycogen is both produced and stored directly in the liver. When insulin moves up, the body stores food energy as glycogen.
When insulin falls, as with fasting, the body breaks the stored glycogen back down into glucose. Liver glycogen lasts approximately 24 hours without eating.
Glycogen can only be used to store food energy from carbohydrates and proteins. It does not store energy from dietary fat, because it is not processed in the liver, and does not break down into glucose.
