Answer: On topographic maps, elevation is shown by using contour lines. The difference in elevation between one contour line and the next is called the contour interval. The contour interval is selected based on the relief of the area being mapped. Every fifth contour line is darker than the four lines one either side of it.
Explanation:
The mosquito would become more prone to injury due to a weakening of its Exoskeleton.
Exoskeleton, a hard or flexible covering that supports and shields an animal's soft tissues. The phrase refers to the chitinous integument of arthropods, such as insects, spiders, and crustaceans, and includes the calcareous housings of sessile invertebrates like clams. The exterior waxy, water-resistant covering of the arthropod exoskeleton, which is made from the epidermis, is covered by chitinous, and flexible layers. This coating features tiny breathing openings in terrestrial species (spiracles). The exoskeleton has made it possible for arthropods, particularly insects, to overrun the majority of terrestrial ecosystems by avoiding dehydration. Exoskeletons of animals like the lobster have flexible joints that allow for remarkable mobility.

Answer. Any tumor that arises from the glial (from the Greek word for “glue”), or supportive tissue, of the brain is called a “glioma.” One type of glioma is the astrocytoma.
