Virus Structure Virus Structure Viruses are not plants, animals, or bacteria, but they are the quintessential parasites of the living kingdoms. Although they may seem like living organisms because of their prodigious reproductive abilities, viruses are not living organisms in the strict sense of the word. Without a host cell, viruses cannot carry out their life-sustaining functions or reproduce. They cannot synthesize proteins, because they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger RNA into viral proteins. Viruses cannot generate or store energy in the form of adenosine triphosphate (ATP), but have to derive their energy, and all other metabolic functions, from the host cell. C-MORE | Events The ocean contains a universe of small wonders, an interconnected web of life. Marine microbes are the root of all this life. Below is a simplifed version of how energy and matter are transferred in the ocean.

Concord: The Concord Consortium, 2011, March 14. Christmas Lectures 1977: The Planets What exists beyond Earth? Over six lectures presented in 1977, American astronomer and cosmologist Carl Sagan explores the vast expanse of space that surrounds the third planet from the Sun. Life on Earth Where at first we could only discern the size of our planet and some knowledge of its atmosphere and configuration, the evolution of planetary exploration has revealed not only intricate details of Earth’s climate and geology, but a multitude of stars and planets besides our own.
Hawai‘i Institute of Marine Biology | Welcome The Hawai‘i Institute of Marine Biology is a world-renowned marine research institute of the School of Ocean & Earth Science & Technology at the University of Hawai'i at Manoa. Situated on Moku o Lo'e (Coconut Island) in Kane‘ohe Bay, HIMB provides excellent opportunities for tropical marine research located just 15 miles from the main campus and downtown Honolulu. HIMB offers cutting edge research facilities for faculty, students, and visiting scientists coupled with convenient access to a diverse range of marine environments. For example, Coconut Island is surrounded by 64 acres of coral reef designated by the state of Hawai‘i for research activities only as the Hawai‘i Marine Laboratory Refuge. Research at HIMB covers many disciplines of tropical marine science such as coral ecology, biogeochemistry, and evolutionary genetics.
