Scientists may conclude the climate was very warm during a particular time if they discover many fossils of A) fish. B) birds. C) insects. D) tall trees. - It's well known that big animals, like polar bears, are vulnerable to climate change. The Earth warms, polar ice melts, and the bears are out of luck.

The insects' feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water's surface D. The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next. Start studying 2 and 3 study. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Portugal (Portuguese: [puɾtuˈɣal]), officially the Portuguese Republic (Portuguese: República Portuguesa [ʁɛˈpuβlikɐ puɾtuˈɣezɐ]), is a country located mostly on the Iberian Peninsula, in southwestern is the westernmost sovereign state of mainland Europe, being bordered to the west and south by the Atlantic Ocean and to the north and east by l and largest city: Lisbon, 38°46′N 9°9′W / .   Nuclear reactors have complex cooling systems that absorb the heat given off by the fission reaction. The absorbed heat is used to produce steam to drive a generator, thus producing electrical energy. Cooling the steam for re-use requires a large amount of cool water, which is usually obtained from a nearby river or lake. A large amount of hot water is then released into the river or lake.

Hydrobiologia, 38(2), pp   In warmer months, waxwings will fly out over water from exposed perches, much like flycatchers, and snatch emerging aquatic insects such as mosquitoes, midges, mayflies, caddisflies and dragonflies out of the air.

They also glean for vegetation-borne insect prey, such as scale insects. Emergence can be as early as January in lowland England (Langford ) or as late as May in in a British river, warmed by cooling-water from a power station. - Hydrobiologia Life cycles of benthic insects in Lapland streams (Ephemeroptera, Plecoptera, Trichoptera, Diptera Simuliidae).

- Oikos in a British river, warmed by cooling-water from a power sta-tion. Radford and Hartland-Rowe () described the life cycles of some stoneflies and mayflies in Alberta, and con-cluded that there seems to be a strong correlation between life cycles and food availability.

How to Do Warm Bugs, Cold Bugs: Step 1: On a warm day, check an outdoor thermometer to see the temperature. Take your notebook and sit near the flower border where you can see insects. Step 2: Pick a patch of flowers about a yard square.

Every few minutes, count how many insects. You spray an insect with an organophosphate insecticide. How does it kill the insect. It prevents diffusion of acetylcholine at the synapse B.
