Answer the following question given this paragraph: Channel proteins provide an open channel or passageway through the cell membrane for molecules to move across. Many channel proteins allow the diffusion of ions. Ions are charged atoms. The charge makes it difficult to cross the cell membrane without assistance. Channel proteins are specific for the molecule they transport. For example a sodium ion crosses the membrane through a channel protein specific for sodium ions. Q: Ions are charged what? A:

OPTIONS:
- molecules
- protons
- isotopes
- atoms

Answer: atoms

Problem: OPTIONS:
- sound waves

Answer: radio waves

Problem:OPTIONS:
- metabolic
- plasma
- systolic
- diastolic

Answer the following question given this paragraph: 40.4 | Blood Flow and Blood Pressure Regulation By the end of this section, you will be able to: Describe the system of blood flow through the body Describe how blood pressure is regulated Blood pressure (BP) is the pressure exerted by blood on the walls of a blood vessel that helps to push blood through the body. Systolic blood pressure measures the amount of pressure that blood exerts on vessels while the heart is beating. The optimal systolic blood pressure is 120 mmHg. Diastolic blood pressure measures the pressure in the vessels between heartbeats. The optimal diastolic blood pressure is 80 mmHg. Many factors can affect blood pressure, such as hormones, stress, exercise, eating, sitting, and standing. Blood flow through the body is regulated by the size of blood vessels, by the action of smooth muscle, by one-way valves, and by the fluid pressure of the blood itself. Q: What blood pressure reading measures the pressure in the vessels between heartbeats? A:
****
A: diastolic

Answer the following question given this paragraph: Acne Acne is a skin disturbance that typically occurs on areas of the skin that are rich in sebaceous glands (face and back). It is most common along with the onset of puberty due to associated hormonal changes, but can also occur in infants and continue into adulthood. Hormones, such as androgens, stimulate the release of sebum. An overproduction and accumulation of sebum along with keratin can block hair follicles. This plug is initially white. The sebum, when oxidized by exposure to air, turns black. Acne results from infection by acne-causing bacteria (Propionibacterium and Staphylococcus), which can lead to redness and potential scarring due to the natural wound healing process (Figure 5.22). Q: Acne is a skin disturbance that typically occurs on areas of the skin that are rich in sebaceous glands (face and back). it is most common along with the onset of puberty due to association with these? A:
OPTIONS:
- mental changes
- digestive changes
- thermal changes
- hormonal changes
hormonal changes
