Hard bones provide primary support for the endoskeleton while more flexible cartilage is found at the end of all bones, at the joints, and in the nose and ears. In addition to providing support and protecting bodily organs, bones also produce blood cells and store minerals like calcium.
More familiar in the United States is the Fahrenheit scale in which the freezing point of water is 32°F (0°C) and the boiling point is 212°F (100°C). To convert from C° to F° use the formula:
\(F° = {9 \over 5}C° + 32\)
and to convert from F° to C° use:
\(C° = {5 \over 9} (F° - 32)\)
Vitamin / Mineral | Sources | Health Benefits |
---|---|---|
Calcium | Dairy products (milk, yogurt, cheese), spinach. | Aids bone growth and repair, muscle function. |
Iron | Red meat, beans, whole grains. | Allows red blood cells to transfer oxygen to body tissues. |
Magnesium | Nuts, whole grains, green leafy vegetables. | Muscle, nerve, and enzyme function. |
Potassium | Bananas, nuts, seeds. | Helps balance fluid levels in the body. |
Vitamin A | Liver, milk, eggs, carrots. | Vision, immune system, cell growth. |
Vitamin C | Green and red peppers, citrus fruits, broccoli. | Collagen formation, immune system function, antioxidant (helps protect cells from damage). |
Vitamin D | Exposure to sunlight. | Helps calcium strengthen bones, muscle, nerve, and immune system function. |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Food is mixed with gastric acid and pepsin in the stomach to help break down protein.
