Genetic Analysis Of A Short-Petjolule Type Soybean
(5 Pages, 59.75 USD)
|
|
5 pages in length. In this particular scientific analysis, the researchers sought to either prove or disprove the incidence of short-petjolule type soybean plants relative to that of a recessive gene that exists within the hereditary composition. Bibliography lists 1 sources.

Alfalfa and 'Yellow Rocket' (Barbarea vulgaris)
(6 Pages, 71.7 USD)
|
|
This 6 page report discusses the interaction between alfalfa crops and a common weed. The weed chosen for examination is Barbarea vulgaris, most commonly known as 'yellow rocket.' Yellow rocket is usually biennial or perennial with some plants flowering, setting seed and dying after their first growing season; reproducing only by seed but the seeds are notable for their ability to germinate with minimal soil requirements. Yellow rocket and other weeds reduce alfalfa production during establishment by competing with and choking out young alfalfa seedlings, invade established alfalfa fields, and reducing forage quality and yield. Several aspects of intervention and eradication are discussed. Bibliography lists 6 sources.

Effect of Environmental Conditions on the Germination of Erigeron Species
(15 Pages, 179.25 USD)
|
|
A 15 page scientific report regarding the germination rates of two species of fleabanes, Oregon fleabane (Erigeron speciosus) and Piper's Daisy (Erigeron piperianus). Provides information regarding the distribution and ecologies of the two species, their importance from both agricultural and ecological standpoints, and information (based on the unpublished work of Ronald J. Burkey at Washington State University Agricultural Research Center in Prosser WA) regarding their relative germinations under varying planting depths, soil types, cold treatment verses no cold treatment, and light exposure verses germination in the dark. Bibliography lists 8 sources.

The Bartrams / A Special View of Nature
(4 Pages, 47.8 USD)
|
|
a 4 page research paper that looks at Thomas P. Slaughter's account of the lives of John and William Bartram-father and son, they were two of America's first horticulturists and botanists. Ahead of their times in many ways, the writer shows that science is substantiating many of their opinions. Bibliography lists 2 sources.

Temperature Regulation in Animals
(5 Pages, 59.75 USD)
|
|
A 5 page review of thermoregulation in animals. Discusses the differences between ectothermia and endothermia in reptiles, fish, mammals and birds. Discusses animals classified as poikilothermic, having a body temperature which fluctuates widely, and those classified as homeothermic, having a narrowly constricted body temperature range. Includes a representative graph of these variations and a graphic showing bones structure and its relevance. Bibliography lists 5 sources.

Bat Echolocation: The Perception of Distance and Depth Through the use of Sonar
(4 Pages, 47.8 USD)
|
|
This 4 page paper provides an overview of the basic elements of bat echolocation as an process that is separate from the auditory and visual receptive capabilities of other mammals. This paper considers the prevalent biological structures and other components of bat physiology that determine the capacity for echolocation, also known as sonar. Bibliography lists 4 sources.

Brood Parasitism Among the Common Cuckoo (Cuculus canorus): Genetic or Behavioral?
(14 Pages, 167.3 USD)
|
|
A 14 page literature review of brood parasitism among the common cuckoo (Cuculus canorus). Explores the concept of whether genetic makeup determines host preference or if this phenomena is really a result of the mature bird seeking out habitat in which it was raised and consequently encountering more nests of a specific species in that habitat than would be present in others (i.e. natal philopatry). Includes a 1 page Roman numeral outline. Bibliography lists 8 sources.

The Human Digestive System / Its Phylogenetic and Ontogenetic Development
(7 Pages, 83.65 USD)
|
|
A 7 page exploration of the concepts of phylogeny and ontongeny in relation to the digesive system. Discusses the embryonic development of the digestive system and points out that, although it is possible that certain phases of our evolution are reflected in our embryonic development, this reflection is sporadic and quite different from the view held in the nineteenth century that an organism's embryological developmental phases give a clear picture of its evolutionary history. Bibliography lists five sources.

Motor Executions And The Role Of The Central Nervous System
(7 Pages, 83.65 USD)
|
|
A 7 page overview of the role of the central nervous system in motor functions. Specific information is provided about such components of the central nervous system as the cerebral cortex, basal ganglia, and neurons. Bibliography lists 10 sources.

The Process Of Osmosis
(6 Pages, 71.7 USD)
|
|
A 6 page overview of osmosis in the living organism and in industrial applications such as desalination, sewage treatment, and groundwater treatment. The term osmosis is used to denote the process by which liquids move through a semipermeable membrane. Bibliography lists five sources.
