Cell transport is useful because it's, essentially, the movement of cells across the blood/veins. Active transport uses energy, while passive transport does not.
Pituitary gland.
When you feel stress, the pituitary gland, at the base of the brain, increases its production of the hormone ACTH. This hormone tells the adrenal glands, found at the top of your kidneys, to increase their production of hormones. These stress hormones help you to concentrate, speed your reaction time, and boost your strength. Your hypothalamus also helps your body respond to stress.
Answer:
The correct answer is ''shield volcano.''
Explanation:
Shield volcanoes are those whose diameter is much greater than its height. They are formed by the successive accumulation of very fluid lava flows. So they are of considerable height and slight slope. Its topography is smooth and its top forms a poorly defined depression. Lava ejected during an eruption is largely basaltic in composition and has a very low viscosity (it is liquid). Because of this, lava flows easily and spreads over a large area.
Shield volcano eruptions generally involve lava that travels great distances and spreads out in thin layers. As a result, the volcanic mountain that is built over time by repeated lava flows has a broad, smooth profile leading away from a bowl-shaped depression at the top known as a caldera.
