What else can I help you with?
Which feedback mechanism causes the variable to deviate further and further from its original value or range?
Positive feedback mechanisms amplify changes in a system, causing the variable to deviate further from its original value or range. This can lead to destabilization or self-reinforcing processes. Examples include childbirth contractions and forest fires.
What is causing depletion of the upper level ozone?
The CFC's released are causing this. These are released by humans.
What binds calcium ions in a smooth muscle causing contraction?
Contractions are initiated by the calcium-activated phosphorylation of myosin rather than calcium binding to troponin.
What would happen to people exposed to a chemical warfare agent that blocked acetylcholine from binding to muscle receptors?
Muscle contractions would be prevented, causing paralysis.
What kind of feedback mechanism help maintain homeostasis causing a stimulus to increase?
YES, + feedback systems enhance or intensify the stimulus. Eg. of a + feedback system = childbirth
Goosebumps are caused by contractions of what muscles?
The "arrectores pilorum" or hair erector muscles elevate the hair follicles above the rest of the skin causing what we call " Goose Bumps "
What do hiccups look like in dogs?
Hiccups in dogs may appear as sudden, involuntary contractions of the diaphragm, causing a quick, repetitive sound or movement in the chest or abdomen.
How do you effectively lie?
When you lie endorfins are released on your nose causing it to itch. Do not scratch your nose, do not blink a lot, and use contractions such as wouldn't instead of would not. Actually, endorphins are only released by the brain. They cannot be released by your nose. Although the above answer about "don't scratch your nose" whilst lying, or contradicting yourself. Looking directly at the person you're lying to helps, rather than looking over their shoulder, or to your left.
What medical condition has peristaltic contractions as one of its symptoms?
Peristaltic contractions are defined as the contraction of smooth muscles that moves food through the digestive system. In some cases, a medical condition can lead to spasms in these muscles causing pain or difficulty in swallowing. A few of the more common causes include pyloric stenosis and an intestinal obstruction.
What causes the power stoke in muscle contractions?
The power stroke in muscle contractions is primarily caused by the interaction between actin and myosin filaments within the muscle fibers. When calcium ions are released into the muscle cell, they bind to troponin, causing tropomyosin to shift and expose binding sites on actin. Myosin heads then attach to these sites, forming cross-bridges. The power stroke occurs when the myosin heads pivot, pulling the actin filaments inward, which shortens the muscle fiber and generates force.
How do glycerin suppositories work?
Glycerin acts as a lubricant and a mild irritant and stimulates the muscles of the intestine, causing it to contract. The contractions help to move the stools along and makes passing them out of the body much easier.
Is it true that the bowel and bladder empty after death?
Not usually. Well, not all the way. What moves "stuff" thru your bowels is peristalsis, which is small muscle contractions in your intestines. These contractions force the digested material thru your bowels. But when you die, obviously, these contractions stop. But the muscle at the end of your bowel (sphincter) also stops functioning (looses muscle tone) so some material may, thru gravity or other movements, find its way out.
