Calories are the energy in food. Your body has a constant demand for energy and uses the calories from food to keep functioning. Energy from calories fuels your every action, from fidgeting to marathon running.
Carbohydrates, fats and proteins are the types of nutrients that contain calories and are the main energy sources for your body. Regardless of where they come from, the calories you eat are either converted to physical energy or stored within your body as fat.
These stored calories will remain in your body as fat unless you use them up, either by reducing calorie intake so that your body must draw on reserves for energy, or by increasing physical activity so that you burn more calories.
Tipping the scale
Your weight is a balancing act, but the equation is simple: If you eat more calories than you burn, you gain weight. And if you eat fewer calories and burn more calories through physical activity, you lose weight.
In general, if you cut 500 to 1,000 calories a day from your typical diet, you'll lose about 1 pound (0.5 kilogram) a week.
It sounds simple. However, it's more complex because when you lose weight, you usually lose a combination of fat, lean tissue and water. Also, because of changes that occur in the body as a result of weight loss, you may need to decrease calories further to continue weight loss.
The bones for the fingers and the toes are the phalanx.
Answer:
A contractor who hired two sub-contractors to help work on the house would be most like to osteoblast.
Explanation:
Osteoblasts are cells that build bone, just like contractors build a house. They are cells capable of synthesizing the bone matrix, allowing the formation and growth of bone.
As bone-forming cells, osteoblasts have a large number of mitochondria and a developed Golgi apparatus. They can multiply until they are covered by the bone matrix, becoming known as osteocytes.
The other options are not correct because:
- <em>Osteogenic
: related to bone.</em>
- <em>Osteocycle
: bone cell in its mature shape.</em>
- <em>Osteococlast : cells capable of remodeling the bone, breaking it and allowing the action of the osteoblasts.</em>
Answer:
Ready to eat food that was prepped by a food handler must have a label that includes:
- <em>use by date</em>
- <em>temperature to keep the food</em>
Explanation:
All foods prepared have specific temperatures where they are best to be kept. For example, most of the desserts need to be refrigerated. Hence, it is important that a food handler mentions the temperature or just mentions whether the food can be refrigerated or not.
The name of the food should be labelled by the food handler to avoid any confusion.
A food handler must mention the date by which the food can be consumed. As the food might not have preservatives in it, the food most likely will have to be used within a short time.
