Astrobiology Textbooks Notes Introductions: Chapter One Astrobiology= combination of astronomy (study of universe) and and biology (study of life); “literally the study of life in the universe” What are we searching for? extraterrestrial life‚ life beyond earth we are looking for any sign of life‚ be it simple‚ complex‚ or intelligent The basis for life Life can move so can clouds Life can grow so can crystals Life can reproduce and spread so can fire The scientific search for

Diversity: variety of species and relative abundance of the species in an area The more species‚ the more complicated and robust‚ allowing survival in environmental changes Each species has its own contributions Species Description Sulfolobus archaea Live in hot springs‚ mini organisms Sea wasp/Box jellyfish Live in tropical oceans Giant sequoia trees Grow in North America‚ Europe‚ Australia and New Zealand Blue green algae Live everywhere‚ ocean‚ soil‚ bare rock‚ hair of sloth Ants Everywhere

Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

Photochemistry‚ a sub-discipline of chemistry‚ is the study of the interactions between atoms‚ small molecules‚ and light (or electromagnetic radiation).[1] The pillars of photochemistry are UV/VIS spectroscopy‚ photochemical reactions in organic chemistry and photosynthesis in biochemistry

Premium Chromosome Mitosis
The human body is the entire structure of a human being and comprises a head‚ neck‚ trunk (which includes the thorax and abdomen)‚ arms and hands‚ legs and feet. Every part of the body is composed of various types of cell.[1] At maturity‚ the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that
