Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body. Kevin and his cousin Darlene both enjoy jogging for exercise. One day, Kevin goes out for a jog in his local neighborhood when the amount of heat outside is quite high, and he begins to sweat a lot and starts to feel a bit dizzy. On the same day, Darlene goes jogging in her neighborhood when the amount of heat outside is low and she feels perfectly normal as she continues to jog. Who is more likely to be experiencing electrolyte deficiency?

Answer: Kevin

An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation and ecotourism. Two cousins were fascinated about food chains in nature. Liam started reading about apex predators, while Fox read about grazers and large herbivores. Which cousin learned less about predators with no natural predators?

Answer: Fox

A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. Danny went camping and made a fire in the woods. he used large logs he fell a few months back. Bob was camping 300 yards away and he made a fire using small sticks, kindlings and sawdust he had left over. Bob's fire burned fast and bright. Which person made a fire that burned for a longer time?
