Harold is a 50-year-old, overweight, diabetic, hardworking father of three. He has a 15-year smoking addiction. He isn’t crazy a
bout his job and has a habit of scratching his head while sitting at his desk. For the past several months he has noticed dandruff-like flakes falling onto his paperwork. He assumed this was due to dandruff and has been using a dandruff shampoo, with no improvement. Harold has also noticed that his fingernails are pitted and discolored. Today he is itching around his belt line. This is nearly as distracting as the itchy, scaly patches on his anterior knees and the posterior surfaces of his elbows. These round patches are raised, reddened, and scaly with silvery plaques. They are tender and have been enlarging and worsening for the past few weeks. Harold is so concerned about these skin lesions that he consults a dermatologist (skin doctor), who performs a skin biopsy. The dermatologist comments that, under the microscope, the tissue looks like epidermis in "overdrive."Every day your epidermis normally sheds dead skin cells. What is the first step in the process by which epidermal cells are replaced?
It takes about 28 days for young skin cells to reach the surface, however in mature skin they need more time. And that's why more dead cells accumulate in the skin, because the process is slower. When the cells are formed, they will begin to move towards the surface of your epidermis. This usually lasts about from two weeks to a month. The more mature cells die and reach the surface of your skin, detach from your body in the form of scales.
Because humans have five senses: feel, see, taste, hear, and smell. When you step on a nail you basically going to feel it and you brain can sense that and it can trigger nerves which can cause pain.

ment, social development, and the five senses. In each cell of the table, list an appropriate skill or learning that takes place during that month. Then, design a toy that would help the baby learn a critical skill for each of the twelve months. Describe what the toy looks like (for example, size, colors, if it makes sounds) and why you designed it the way you did.
Difussion occurs from a high concentrated region to a low concentrated region. The velocity of diffussion is proportional to the differential of concentrations. In the lung arrives blood with low levels of oxygen while the long is rich with fresh oxygen so the oxygen flows from the lung tissues to the blood.
The other tissues consume oxygen continually them they get poor in oxygen and so the oxygen that is in the blood diffuses to the tissue that is poor in oxygen.
