Q: Answer the following question given this paragraph: Chemical reactions always involve energy. When methane burns, for example, it releases energy in the form of heat and light. Other chemical reactions absorb energy rather than release it. Q: Chemical reactions always involve energy. when methane burns, for example, it releases energy in the form of what? Choices: - movement and light - light and sound - heat and movement - heat and light A:
A: heat and light

Q: Answer the following question given this paragraph: 17.6 | The Adrenal Glands By the end of this section, you will be able to: Describe the location and structure of the adrenal glands Identify the hormones produced by the adrenal cortex and adrenal medulla, and summarize their target cells and effects The adrenal glands are wedges of glandular and neuroendocrine tissue adhering to the top of the kidneys by a fibrous capsule (Figure 17.17). The adrenal glands have a rich blood supply and experience one of the highest rates of blood flow in the body. They are served by several arteries branching off the aorta, including the suprarenal and renal arteries. Blood flows to each adrenal gland at the adrenal cortex and then drains into the adrenal medulla. Adrenal hormones are released into the circulation via the left and right suprarenal veins. Q: What glands are wedges of glandular and neuroendocrine tissue adhering to the top of the kidneys by a fibrous capsule? Choices: - heart glands - nutrients glands - fatty glands - adrenal glands A:
A: adrenal glands

Q: Answer the following question given this paragraph: In general, for an electric charge to move from one position to another, there must be a difference in electric potential energy between the two positions. The difference in electric potential energy is called potential difference, or voltage . Voltage is measured in an SI unit called the volt (V). For example, the terminals of the car battery in Figure below have a potential difference of 12 volts. This difference in voltage results in a spontaneous flow of charges, or electric current. Q: The difference in electric potential energy which allows for an electric charge to move from one position to another is measured by what si unit? Choices: - ohm - joule - meter - volt A:
A: volt

Q: Answer the following question given this paragraph: of the proximal tibia. This versatile muscle flexes the leg at the knee and flexes, abducts, and laterally rotates the leg at the hip. This muscle allows us to sit cross-legged. The posterior compartment of the thigh includes muscles that flex the leg and extend the thigh. The three long muscles on the back of the knee are the hamstring group, which flexes the knee. These are the biceps femoris, semitendinosus, and semimembranosus. The tendons of these muscles form the popliteal fossa, the diamond-shaped space at the back of the knee. Q: The three long muscles on the back of the knee are part of which group? Choices: - synovial joint - patella - adductors - hamstring group A:
A: hamstring group
