Explain how technology was a stimuli to the Age of Discovery? There were many technological advances in the Age of discovery. The development of the cannon‚ which was able shoot iron or stone balls. This device could take down city walls or fortresses. A western technician built 56 small cannon’s and gigantic gun that could hurl stone balls weighing 800 lbs. The gun could only be loaded and fired only by about a hundred men working together‚ and reloading took 2 hours. Although the cannon had serious

as blowflies and centipedes‚ sufficient food and damp. The ground was mostly made up of damp organic matter‚ damp soil‚ moist leaves‚ some were found on stony ground. The light intensity is significant to the niche and way of life of the Slater because they are classed as scavengers; they live off decomposing matter and if the matter was in an open place they could get eaten by predators. The Slaters found were in groups this was due to clumping of the slaters. Slaters are prone to desiccation‚

mechanics of agonistic behavior‚ the causes and various stimuli that encourage agonistic behavior must be studied. This research investigated three Betta splendens and their response to various stimuli in order to depict whether or not they reacted most strongly against each other. It was found that to a minimal degree‚ Betta splendens exhibited more aggressive behavior to other Betta splendens as opposed to when faced with a mirror. This insinuates that natural selection is occurring amongst Betta

main purpose of the economic stimulus package was to prevent the re-emergence of the panic that gripped investors in 2008. It also aimed to restore trust in the finance industry by further limiting bonuses for senior executives for companies that received TARP funds (Recovery.gov). The $787 billion economic stimulus package was approved by Congress in February‚ 2009. The plan was to jumpstart economic growth‚ and save between 900‚000 - 2.3 million jobs. The economic stimulus bill allocated funds as follows:

Skeletal Muscle Lab Introduction: Motor neurons and muscle fibers are the building blocks of motor units and where they intersect is called the neuromuscular junciton. The region where the flattened end of a motor neuron transmits neural impulses to a muscle is the motor end-plate. The end plate potentials depolarizes skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. The process of contraction of the muscle cell is called excitation-contraction

printed graph‚ you measure the time between the application of the stimulus and the beginning of the first observable response(increase in force). The computer can’t “look ahead‚” anticipating the change in active force. To measure the length of the latent period using the computer‚ click the Measure button. Then click the right arrow button next to the Time window repeatedly until you notice the first increase in the Active Force window. This takes you beyond the actual length of the latent period. Now
