Gene - Linear sequence of nucleotides, coding instruction for transcription of RNA, and translation to a protein Anaximander (610-546 BC) - Speculated: Early animals rose from the ocean, humans came from the mouths of giant fish, and complexity rose from simple life. Aristotle (384-322 BC) - Advocated the importance of observation, wrote "History of Animals", also wrote "Scala Natural" Biological Evolution - Change in populations over time Biology - Study of Life Carolus Linnaeus () ...

Earth rocks vs Moons rocks correct answers Almost all Earth rocks contain 1 to 2 percent water, either as free water trapped in the rock or as water molecules chemically bonded with certain minerals. In contrast, the Moon rocks brought back by the Apollo astronauts contain very little water. Why are features like the Moon's maria not observed on Mercury? correct answers Mercury's lava plains are not significantly darker than the rest of the planet's crust, so they are not so clearly percep...

In the process of nuclear fusion - two or more nuclei fuse or stick together to form a heavier nucleus whose combined mass is slightly less than the original nucleus Beneath the surface of which moon of Saturn is there evidence for the existence of a subsurface ocean of liquid water? - Enceladus Apparent retrograde motion occurs when a planet appears to - move westward with respect to background stars A chemoautotroph gets its energy from - chemical reactions and its carbon from its enviro...

Alfred Russel Wallace ( - Answer-Naturalist, known for explorations in SE Asia. Considered "After of Biogeography". (Wallace and Weber Lines on maps) Anaximander (610-546 BC) - Answer-Speculated: Early animals rose from the ocean, humans came from the mouths of giant fish, and complexity rose from simple life. Aristotle (384-322 BC) - Answer-Advocated the importance of observation, wrote "History of Animals", also wrote "Scala Natural" Biological Evolution - Answer-Change in populati...

Lamarck's proposal of evolution - 1. Originally, giraffes had short necks. 2. Giraffes stretched their necks in order to reach food. 3. With continual stretching, most giraffes now have long necks. Darwin's proposal of evolution - 1. Originally, giraffe neck length varied. 2. Struggle to exist causes long-necked giraffes to have the most offspring. 3. Due to natural selection, giraffes now have long necks. Darwin completed a five-year journey around the world on what? And what did he...

What is marine biology? - The study of life in the sea A subsection of marine science Oceanography - •Geological Oceanography •Physical Oceanography •Chemical Oceanography •Biological Oceanography Why study marine science? - • Diversity! •71% of the Earth's surface is covered by the oceans •Ocean makes up 99% of living space • History! •Life originated in the sea -We still develop in water • Resources! -$20 trillion/year Ancient Marine Science - •Ancient migr...

Macroevolution changes in a population over very long periods of time. Speciation the splitting of one species into two or more new species Biological Species Concept offers testable way to define a species that does not depend on appearance: The members of a species interbreed and have a shared gene pool, & each species is reproductively isolated from every other species. Gene flow occurs between the populations of a species, but not between pops of diff species. Biolo...

Pacific Ocean correct answers Deepest and largest ocean Atlantic Ocean correct answers Second largest ocean; separates the Old World from the New World Indian Ocean correct answers Slightly smaller than the atlantic ocean but has the same average depth; mostly in the southern hemisphere Arctic Ocean correct answers Smallest and shallowest ocean; has a permanent layer of sea ice Antarctic or Southern Ocean correct answers Ocean that connects the pacific, atlantic and indian oceans; so...
