BIOLOGY REVIEW Cells are the basic unit of life and often combine with other cells to form tissues. 3. The image above is of a plant cell. You can tell by the shape of the cell. Plant cells tend to be rectangular shaped while animal cells are circular. Plant cells have a cell wall and have a large central vacuole. 5&7. In the cell cycle, the cell grows and prepares for cell division. The cell is in interphase when it is preparing for division. Cell division involves the splitting of the

host nitrogen-fixing bacteria of the actinomycetes group. Rice benefits indirectly from symbiotic nitrogen fixation because it is often cultivated in paddies with the water fern Azolla, which has symbiotic nitrogen-fixing cyanobacteria. • This increases the fertility of the rice paddy through the activity of the cyanobacteria. • The growing rice eventually shades and kills the Azolla. • The decomposition of water fern adds more nitrogenous compounds to the paddy. The molecular biology of

An average adult coyote is the size of a golden retriever dog and eats mice, rodents and various birds such as quail, doves and pheasants. Coyotes are a grey color and can be found clumped in packs. They will hunt at night or day, whenever they need to find food, but are primarily day time creatures. They only have pups once a year, in the spring, and they have them in litters

red blood cells for both the human and bird blood cells were identified and the size was estimated through the estimated number of cells that could fit across the diameter. However the white blood cells were not observed as they could not be identified under the light microscope. This is due to the fact that white blood cells make up less than 0.1% whilst red blood cells make up 45% of the substance (NSW Biology 2007). Therefore the number of white blood cells was estimated by using the equation

Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has
