Answer:
a. Glucagon is released by the beta cells of the pancreatic islets of Langerhans.
Explanation:
When the body is fasting, the pancreas releases glucagon so that your body can produce glucose. Glucagon is a protein hormone made and secreted by alpha cells from pancreatic islets (or islets of Langerhans).
The islets of Langerhans are a special group of cells in the pancreas that produce not only glucagon, but also insulin. These substances act as important regulators of sugar metabolism.
Question number 2 the dna the answer is number 4 the last one
Explanation:
Surface currents in the Northern Hemisphere rotate in a Clockwise direction whereas in the Southern Hemisphere, the surface currents rotate in a anticlockwise direction. This happens because of the Coriolis effect, because of this Coriolis effect surface currents are shifted to angle of 45°. Therefore, it deflects the current towards right in northern hemisphere and towards left in southern hemisphere.
Answer:
A. To identity high- and low-pressure systems
Explanation:
Isobars are similar to the level lines on a topographic map, showing areas of similar pressure, they are also drawn in circles to represent the areas of similar air pressure over a geographical map.
Isotherms are usually displayed in color showing areas over a map that have the same temperature or are covered by a similar temperature system (heat or cold front for example).
Both are used in electronic media mostly (although in print in newspapers too), over a geographic map to position the systems.
