... spawn in the spring, when water temperatures begin to move past sixty degrees fahrenheit. The spring spawning urge in a bass is set off by both water temperature and photoperiod. Photoperiod is the proportion of the day in which the bass are exposed to sunlight. As the day light hours grow longer through the spring and early summer, so does the photoperiod. This process affects the temperature of different bodies of water in different ways. Small shallow ponds heat up much earlier in the year. As a result the bass will begin to spawn much earlier than the bass in large lakes. They will also fini ...

... rock called aa. Pahoehoe and aa cover large areas of Hawaii, where
the terms originated. The stickiest lava forms flows of boulders and rubble
called block flows. It may also form mounds of lava called domes.
Other lava formations are spatter cones and lava tubes. Spatter cones
are steep hills that can get up to 100 feet high. They build up from the spatter
of geyser-like eruptions of thick lava. Lava tubes are tunnels formed from fluid
lava. As the lava flows, its exterior covering cools and hardens. But the lava

... way, the author used effective illustrations and examples to prove his point. These examples and illustrations simplified the readers understanding as to how severe acid rain is and how we can try to prevent it. For instance, one great illustration adopted in the essay reports, “Lumsden Lake, on the north shore of Ontario’s Georgian Bay, twinkles like a sapphire in a setting verdant forest and sparkling quartz.
Blue, incredibly clear, and seemingly pure, just twenty years ago it abounded in fish. But now, this exquisite lake is dead, it’s fish wiped out.” Moreover, another developmental device used ...

... converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Internet today, at speeds of only 53kbps. Even that connection speed is theoretical. Depending on the quality of the telephone lines that run into your home, your connection speed may not even come close to 53kbps. Despite having ever-faster computers, we are limited to what we can do ...
