The nucleus consists of two membranes, one called the NUCLEAR ENVELOPE. The nuclear envelope surrounds the cell's genetic information. This genetic information is contained in structures called CHROMOSOMES. In addition to chromosomes, most nuclei contain a region called the NUCLEOLUS.

∙ 9y agoChromatin is intertwinted mass of fine thread-like structure made of DNA and protein. During cell division (mitosis and meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.

What is the relationship aphelion and perihelion to season?
Perihelion and aphelion have no relationship to the seasons, although they do occurat the same time each year.If you're thinking that the Summer's heat and the Winter's cold are somehow relatedto the Earth's distance from the sun, you need to be reminded that when it's Summerin your hemisphere, it's Winter in the other one. On exactly the same day !And as for the US, Canada, Mexico, Europe, Russia, and everybody else in the northernHemisphere, we are closest to the sun right in the middle of our Winter, in the first fewdays of January.
What is the Microwave disadvantages?
In terms of microwaves themselves, the dangers are largely limited to the effects of the heat generated when the microwaves interact with human tissue. The greatest risk of high power microwaves is to the eyes, where the heat cannot be quickly removed by the cooling effect of the blood supply. Hence, corneas are particularly vunerable to micriwave heating. The testes in males are also vulnerable, although it is generally less likely that they will be exposed to microwaves. In terms of microwave oven use, there are two principle dangers - The first is superheated liquids (liquids above their normal boiling point), which can flash-boil when, for example, instant coffee, sugar, or any other power is added. The second (and at one time the cause of most microwave oven accidents) comes from exploding unbroken eggs, as the yolk heats so efficiently that, even if the egg doesn't explode in the microwave, it can explode in the user's face when it is removed from the microwave oven. There are no reliable reports of adverse health effects from low-level microwaves from such things as mobile phones or telecom masts.

What is the best dog for a pet a mongrel or full bred?
In my opinion, Mongrels end up in shelters and need good homes, Most purebreeds will end up with a home one way or another. So mongrals. But there is little to no difference between the health of a purebred dog and a mongral, and dispotition can be relatedto a breed, but is specific to the dog. =======================================

What effect does energy have on a resistor?
One way to look at the purpose of a resistor is as a device built to dissipateelectrical energy. Some (but usually not all) of the energy of the current througha circuit is always dissipated when it flows through a resistor. The energy lostleaves the resistor in the form of heat.The number of joules of electrical energy lost and heat dissipated by the resistor is(amperes of current through the resistor)2 x (ohms of resistance) x (seconds of time it continues)If you work with resistors often, or see several of them inside an old radio, you noticethat there are physically big ones and physically small ones. The size of the resistorisn't related to the number of ohms of resistance it has. The physical size is relatedto how fast it can dissipate energy (heat) without melting or burning up. A biggerresistor has more air around it, so it can get rid of heat faster.

Can't sociopaths just snap out of it?
In a word: NO.In some more words...Sociopaths are the way they are because, from birth onward, thebrain of a sociopath stores learning information in a random, chaoticway instead of in the usual designated places in the cerebral cortex.Part of this involves lack of crucial neurotransmitters, but as of yetno one knows whether this lack is caused BY the brain abnormality or is the cause OF it. It's probably the former.Since their information -- including emotional information -- isscattered all over both brain hemispheres, it takes too long for thebrain to retrieve and process information, and the entire process ofsocialization becomes so ponderous that ultimately it fails. (See thebook "Without Conscience" by Robert Hare, PhD.)Since the entire cerebral cortex of a sociopath is almost never ata normal level of alertness (their waking brain waves resemble thewaves of a normal person in a light sleep, alpha waves), this may bethe crucial deficiency that cripples the developing child's ability todevelop many aspects of the human mind. As the child grows, some of thebasic mental and emotional skills the rest of the world takes so forgranted never develop, and crucial among these is the thing calledconscience. That one never develops at all.Some people may envy the apparent calm of a sociopath, but theirexistence is misery. They cannot connect with other human beings, andas babies they are so uncomfortable being held that they fight towriggle free of all but the most basic necessary contact. Theirheartbroken parents often blame themselves or the child, never knowingthat what is really wrong with the child is in his or her brain.Under the almost somnolent calm sociopaths project is a constantsense of restlessness and lack of crucial fulfillment that is in truth nothing other than thebasic need all people have to receive stimulation and support fromothers.But a sociopath has no way of receiving this even if it'soffered. The endless frustration of this, and a discomfort that theyare utterly incapable of articulating or even really understanding, is the source of much of their chronic anger and aggression.Plus, since they grow up in constant conflict with authority, theyare most often bitterly angry and sometimes violent adults, brittle andcombatative under a thin veneer of charm. Offered friendship, theyappear to respond, but quickly discover that they can get nothing fromit; they see the obvious pleasure of other people in such contact witheach other, and they often seek to "even it up" by stealing what theycan -- material goods, or even human lives. They are constantly toldhow "bad" they are, and by adulthood, most of them believe it. Andbehave accordingly.Sociopaths rarely feel true happiness. If they do, it is usually inthe condition that some kind of intervention -- such as one of thesmall number of medications made for other conditions that may alsohelp somewhat with theirs -- has taken place, and it will be fleeting.For all their frantic racing around, they are really very dead inside,and this is tragic beyond description.Imagine spending your entirelife trying to get your brain to wake up! And failing. Thousands oftimes.There are stories of people diagnosed as sociopaths who did improveto some degree, with the most ceaseless and diligent help. But sincethe vast majority of this huge body of people (there are more thanthree hundred million sociopaths on Earth) cannot get that kind ofattention, they turn to abusing those they envy, and often to crime. Itis certainly vengeance: "If I can't have any of this, why should you?"This is the real reason sociopaths lash out at strong and kind people.No matter what they say, they know that inside, they are always emptyand damaged beyond repair.Only in neuroscience is there true hope for these incomplete people. Thekey lies in awakening the cerebral cortex of the brain, which is risky because sociopaths aremuch more prone to seizures than the rest of the population, and that-- an uncontrolled blast of electrical discharge spreading through thebrain and causing violent convulsions -- is likely to be the firstresponse from brain pathways that, after years or even decades ofsilence, are suddenly flooded with impulses.But if the devices ofneurosurgeons can be tweaked to avoid this shock, and all else relatedto this idea is workable, it's feasible that small electronic devicesplanted in the brain (these already exist, but are not yet being usedfor mental illness) could open up a closed connection.That leaves us with the problem of whether a lifetime of scatteredinformation can ever be set into order. Probably the best that could behoped for would be a kind of retraining -- like what is now done withstroke survivors and head injury patients -- that would be bothintensive and compensatory.One of the things that would be necessary would be to try tosocialize the person whose congenital birth defect made such a thingcompletely impossible before. Whatever intervention is used, be itdrugs or computer chips or what have you, it would probably -- I'd saycertainly -- be excruciating for the patient at first. With noknowledge of how to cope with the emotions the rest of the world hasbeen dealing with all their lives, the recovering sociopath would berendered as vulnerable as a baby. Which makes sense, because some ofthe most basic aspects of the human mind would be developing from theprimordial stasis in which they had remained since birth!A person thus treated would never be fully normal, but the humanbrain is amazing in the way it adapts and continues to develop allthrough life. And given the utterly joyless and meaningless existence asociopath leads, any improvement is better than none.The matter of missing neurotransmitters in a sociopath is, ofcourse, another problem. Would "waking up" the cerebral cortexeventually stimulate production of these? Or would they have to besynthesized?Only time will tell.
Can a sociopath sleep with you and then make you look like the one who has a mental problem when you don't?
Yes. That's a typical socipathic technique. It's called "projection."First of all, sociopaths can't fall in love; you may think it's love, but it's one-sided at best.Second, sociopaths are not skilled at introspection.Third, sociopaths usually don't know they're messed up. Usually, but not always.So, leave behind the accusations and go on with your life.Only in neuroscience is there hope for these incomplete people. Thekey lies in awakening the brain, which is risky because sociopaths aremuch more prone to seizures than the rest of the population, and that-- an uncontrolled blast of electrical discharge spreading through thebrain and causing violent convulsions -- is likely to be the firstresponse from brain pathways that, after years or even decades ofsilence, are suddenly flooded with impulses.But if the devices ofneurosurgeons can be tweaked to avoid this shock, and all else relatedto this idea is workable, it's feasible that small electronic devicesplanted in the brain (these already exist in a rudimentary form, but are not yet being usedfor mental illness) could open up a closed connection.That leaves us with the problem of whether a lifetime of scatteredinformation can ever be set into order.

This study assessed whether prior findings of aright greater than left (R > L) functional asymmetry in caughtviolent offenders generalize to the structural domain in unsuccessful,caught psychopaths.Methods:Left and right hippocampal volumes were assessed using structuralmagnetic resonance imaging (MRI) in 23 control subjects, 16unsuccessful psychopaths, and 12 successful (uncaught) communitypsychopaths and transformed into standardized space.Results:Unsuccessful psychopaths showed an exaggerated structuralhippocampal asymmetry (R > L) relative both to successfulpsychopaths and control subjects (p < .007) that was localized tothe anterior region. This effect could not be explained byenvironmental and diagnostic confounds and constitutes the first brainimaging analysis of successful and unsuccessful psychopaths.Conclusions:Atypical anterior hippocampal asymmetries in unsuccessfulpsychopaths may reflect an underlying neurodevelopmental abnormalitythat disrupts hippocampal-prefrontal circuitry, resulting in affect dysregulation, poor contextual fear conditioning, and insensitivity to cues predicting capture.Keywords: Hippocampus, psychopathy, MRI, trauma, neurodevelopment, asymmetry.So it is understandable why many people don't think anything at all canbe done to change the sociopath, but in fact, that isn't true. Somekeep trying to help them; giving up is not an option. Sociopaths cause too much trouble. And experience as much.A good therapist can prevent you from victimizing him/her withoutvictimizing you in the process. And, as mentioned above, recent studies made byneurosurgeons and other medical experts have finally begun to pinpointthe things that go awry in the brain that are part of what causessociopathy.In some cases, such medications as Depakote, Topamax, Risperdal, Dilantin, Pentobarbitol, andeven Lithium are being prescribed, and although some individualtherapists prescribe Ativan and the like, much more research needs Tobe done there on ultimate benefit of drug treatment. It is alreadyknown that drug treatment must be augmented by a very structured andpositive-oriented talk therapy.Sociopaths can get somewhere in a specialized form of talk therapy if the clinician isself-confident and relaxed, firm but never authoritarian orself-important. It must not ever become an ego-contest.Once theprocess gets far enough along so that the sociopath is actually able tofeel even a tiny flicker of genuine happiness, that is an impetus thatwill grow stronger if the process continues to move forward.But the emotional response of a sociopath will always be to some degree abnormal.Why does a sociopath cry? Is it like the crying of a "spoiled" child, or is it like the crying of a damaged person?Maybe both.Thenear-constant state of frustration and dissatisfaction felt by a truepsychopath is the source of not only their rages but those eerie,on-and-off-like-a-faucet tears. (Yes, tearsare seen even in some men,though of course still more common in children and women.)Generally, it is considered impossible for sociopaths (as well as autistic individuals) to ever experience love firsthand, and this is a tragedy.
