Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.
Answer: 5. False 6. False
Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.
When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.
The transport mechanism is carrier mediated it does not require energy.

Myocardial infarction, also known as heart attack to most people, is a result of an acute blockage of bloodflow to the heart. If a patient would ask the nurse why he/she is experiencing pain, it is best to tell the patient that chest pain or any discomfort in the arm, shoulder, neck, or back is caused by the decrease of blood flow to heart. Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue. It is important to inform the patient about these symptoms so that he/she will be aware that these are common for people with myocardial infarction and that immediate medical attention is a must.
