Write an article based on this "Check for a less dense cortical bone in humans. Look for the cortical area to be 1/4 the thickness of the whole bone. Notice small holes in the inside of the bone."
article: The cortical bone is the dense outside layer of the bone. Humans, though, tend to have less dense cortical bones than animals do. The area is more porous. In a long bone, like the femur or humerus bone, look at a cross section. In a human, the outer cortical layer will only make up about 1/4 of the area of the bone. Because animals bones are denser, the cortical area will make up about 1/2 of the thickness of the bone.  To look at a cross section, you will need to find a bone that's broken or cut one to look inside it. If you're not sure whether the bone is animal or human, you should definitely call the police before cutting into it. The inside cavity of the bone is called the medullary. In humans, this area typically has small holes in it, called trabecula. Animals, on the other hand, usually don't have these small holes. The inside cavity is often smooth. Similarly, the inside of the human skull will look spongy. On the other hand, something like a sun-bleached turtle shell can look like human skull when it's in pieces, but it won't be spongy inside the bone.

Write an article based on this "Hold the crochet hook Hold the yarn between your fingers."
article: . Grab the crochet hook with your right hand (if you're right-handed) or left hand (if you're left-handed). Hold it like a pencil or a knife, with the hooked portion pointing down and facing you.  To hold the hook like a pencil, turn your hand to the side and hold the thumb, forefinger, and middle finger together. Grab the hook with these fingers, letting it extend just past your fingertips. To hold the hook like a knife, turn your hand down, with your palm pointing at the floor, and close the thumb, forefinger, and middle finger together. Slide the hook into the space between your thumb, forefinger, and middle finger. As you unravel the yarn, hold it taut between the forefinger and thumb of your non-writing hand (the left hand if you're right-handed; the right hand if you're left-handed).  You will need to grab the yarn with the hook as you create stitches. Do not use your fingers to manually twist the yarn around the hook.

article:
Steady the scallions with your non-dominant hand and hold a chef's knife in the other. Instead of placing the knife across the scallions at a 90-degree angle, hold the knife so it's almost parallel to the scallions. Making such an extreme angle will make very long, thin strips of scallions.
