Exercise and physical activity fall into four basic categories—endurance, strength, balance, and flexibility. Most people tend to focus on one activity or type of exercise and think they're doing enough. Each type is different, though. Doing them all will give you more benefits. Mixing it up also helps to reduce boredom and cut your risk of injury.
Though each type is described separately, some activities fit into more than one category. For example, many endurance activities also build strength. Strength exercises also help improve balance.
Endurance- dancing
Strength- Lift weights
Balance-standing on one foot
Flexibility-yoga
Living things need water in their cells. Water is the universal solvent - most of the chemicals a cell needs is dissolved and transported in water. Water is an environment where chemical reactions can occur and water is needed in many of those reactions - like the hydrolysis reaction (needed in the break down of food molecules). If a cell becomes dehydrated chemical reactions slow down. Chemical balance of the cell is changed as waste materials are not removed fast enough, food is not broken down, etc. Water also helps regulate the heat that can build up in a cell during chemical reactions. A dehydrated cell = increase in cell temp. Water content of a cell also affects the pH of a cell environment. Certain reactions occur better at certain pH. Homeostasis is maintaining a balance with the the environment. Without water the balance is upset.
The items of food handling that is most likely to be vulnerable of hazards is the critical control point. The critical control point is a procedure being applied to be able to prevent hazard to be contaminated to the food and in the same time to promote food safety. One of the methods that falls under critical control point is cooking, it is used to kill microorganisms that could be lurking on the food. The reason why it could be vulnerable of hazards because if it not done correctly, it could still preserve the contaminants, making it dangerous and making the people consume it at risk. Just like in cooking, when it is not done correctly, it will preserve the microorganisms, making the people consume it at risk.
