The story of the Trojan War—the Bronze Age conflict between the kingdoms of Troy and Mycenaean Greece–straddles the history and mythology of ancient Greece and inspired the greatest writers of antiquity, from Homer, Herodotus and Sophocles to Virgil. Since the 19th-century rediscovery of the site of Troy in what is now western Turkey, archaeologists have uncovered increasing evidence of a kingdom that peaked and may have been destroyed around 1,180 B.C.—perhaps forming the basis for the tales recounted by Homer some 400 years later in the “Iliad” and the “Odyssey.”
(1) The varying number of muscle fibers that contract
<span>In most muscles, the number of muscle fibers in different motor units ranges from a few to hundreds. The nervous system can thus regulate the strength of contraction in a muscle by determining how many motor units are activated at a given instant and by selecting large or small motor unties to activate. </span>
some muscles are almost always partially contracted. In such muscles, the nervous system my alternate activation among the motor units, reducing the length of time any one set of fibers is contracted. Prolonged contraction can result in muscle fatigue due to the depletion of ATP and dissipation of ion gradients required for normal electrical signals.ing.
<span>(2) varying the rate at which muscle fibers are stimulated </span>
<span>single action potential produces a twitch lasting about 100 msec or less. If a second action potential arrives before the muscle fiber has completely relaxed, the two twitches add together, resulting in greater tension. Further summation occurs as the rate of stimulation increases. When the rate is so high that the muscle fiber cannot relax at all between stimuli, the twitches fuse into one smooth, sustained contraction called tetanus.</span>
Answer: Ras activity would be significantly slower in its response to extracellular signals.
Explanation:
• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)
• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase
• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)

The cell wall is a rigid organelle composed of cellulose and lying just outside the cell membrane. The cell wall gives the plant cell it's box-like shape. it also protects the cell. The cell wall contains pores which allow materials to pass to and from the cell membrane.
