The right option is; C. cinder cone, a pyroclastic flow with no explosion
Basaltic magma is a fluid rock material produced from basalt and it has high amounts of iron and magnesium, and low amounts of silica. Basaltic magma is formed within the earth when a part of the earth's mantle is melted. Basaltic magma produces three different types of lava or volcanic deposits which are scoria, ash or cinder, and lava flows.
(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>
The condition involving strokes and heart attacks caused by clots in unbroken vessels is called thrombosis and the pieces may break loose of the vessel wall and travel in the bloodstream as an embolus
I hope this helps!
Answer:
Option 3, Heuristics
Explanation:
Heuristics thinking implies usage of past experiences or judgments or the memory of most relevant and similar incidents to quickly formulate judgments and solutions and make decisions. Such judgments are biased most of the time as they are based on the perseverance of an individual instead of logic and conceptualization of any scenario or incident
Hence, option 3 is correct
