boomcitylife: photosynthesis
http://boomcitylife.blogspot.com/2010/04/photosynthesis.html
Thursday, 8 April 2010. The general equation for photosynthesis is therefore:. 2n CO2 2n H2O photons → 2(CH2O)n n O2 2n A. Carbon dioxide electron donor light energy → carbohydrate oxygen oxidized electron donor. Since water is used as the electron donor in oxygenic photosynthesis, the equation for this process is:. 2n CO2 2n H2O photons → 2(CH2O)n 2n O2. Carbon dioxide water light energy → carbohydrate oxygen. AsO33-) CO2 photons → CO (AsO43-). Plants absorb light primarily using the pigment chlorophyll...

Friday, 9 April 2010. Skull III, discovered at Locus E in 1929 is an adolescent or juvenile with a brain size of 915 cc. Skull II, discovered at Locus D in 1929 but only recognized in 1930, is an adult or adolescent with a brain size of 1030 cc. Skulls X, XI and XII (sometimes called LI, LII and LIII) were discovered at Locus L in 1936. They are thought to belong to an adult man, an adult woman and a young adult, with brain sizes of 1225 cc, 1015 cc and 1030 cc respectively. (Weidenreich 1937). And Ameri...

boomcitylife: leaf fall
http://boomcitylife.blogspot.com/2010/04/leaf-fall.html
Thursday, 8 April 2010. Leaves are also the sites in most plants where transpiration and guttation take place. Leaves can store food and water, and are modified in some plants for other purposes. The comparable structures of ferns are correctly referred to as fronds. Furthermore, leaves are prominent in the human diet as leaf vegetables. A leaf is considered a plant organ and typically consists of the following tissues:. An epidermis that covers the upper and lower surfaces. The epidermis tissue includes...

boomcitylife: the conifers
http://boomcitylife.blogspot.com/2010/04/conifers.html
Thursday, 8 April 2010. Conifers appear to be one of the taxa that benefitted from the Permo-Triassic extinction event. According to the ICBN it is possible to use a name formed by replacing the termination -aceae in the name of an included family, in this case preferably Pinaceae, by the appropriate termination, in the case of this division -ophyta. Alternatively, "descriptive botanical names" may also be used at any rank above family. Both are allowed. In forestry, the terminology of flowering plants h...

boomcitylife: maples and leaves
http://boomcitylife.blogspot.com/2010/04/maples-and-leaves.html
Thursday, 8 April 2010. Acer is a genus of trees or shrubs commonly known as Maple. Maples are variously classified in a family of their own, the Aceraceae, or together with the Hippocastanaceae included in the family Sapindaceae. Modern classifications, including the Angiosperm Phylogeny Group system, favour inclusion in Sapindaceae. The type species of the genus is Acer pseudoplatanus (Sycamore Maple). The genus is subdivided by its morphology into a multitude of sections and subsections. Maples are pl...

boomcitylife: Neanderthals
http://boomcitylife.blogspot.com/2010/04/neanderthals.html
Friday, 9 April 2010. Homo heidelbergensis ("Heidelberg Man", named after the University of Heidelberg) is an extinct species of the genus Homo which may be the direct ancestor of both Homo neanderthalensis in Europe and Homo sapiens. The best evidence found for these hominin date between 600,000 and 400,000 years ago. H. heidelbergensis stone tool technology was very close to that of the Acheulean tools used by Homo erectus. H heidelbergensis was a close relative (most probably a migratory descendant) o...

boomcitylife: Genus
http://boomcitylife.blogspot.com/2010/04/genus.html
Friday, 9 April 2010. The advent of Homo coincides with the first evidence of stone tools (the Oldowan industry), and thus by definition with the beginning of the Lower Paleolithic. The emergence of Homo also coincides roughly with the onset of Quaternary glaciation, the beginning of the current ice age. In biological sciences, particularly anthropology and paleontology, the common name for all members of the genus Homo is "human.". Humans commonly refers to the species Homo sapiens (Latin: "wise man" or...
