There are questions that could be about the creatures

Oh, it should be a large proportion of psychological effects, and if there is a real bug, it won't only move when you don't move, and if it's a bug, it's moving like this, you should see it.

You should have muscle spasms with mild spasms

But if you have been in this situation for a long time, it is recommended that you go to the hospital for a check-up.

It is possible that some disease is causing your muscles to discharge uncontrollably.

But personally, I think you're still psychological.

If you're just reading the report, or if you feel like the peristalsis is starting to get worse.

That's what your psychology does.

If you go to the hospital for a check-up and are sure it's okay but it's still like this.

I'd suggest you put a rubber band on your hand, and if you feel something squirming, and you start to think about it again, bounce yourself with the rubber band.

Hehe, this is one of the best methods in psychological counseling.

I have a little understanding of biology and psychology and hope it can help you.

Is it a precursor to varicose veins? It is advisable to ask the medical staff.

It's your digestive system that's working! Below the navel is the peristalsis of the large intestine, which is the peristalsis of the large intestine after the food is digested and enters the large intestine to be excreted, and on the navel is the peristalsis of the small intestine, which is the peristalsis of the small intestine after the initial digestion of food from the stomach, and the peristalsis of the small intestine when absorbing nutrients.

Calcium deficiency, muscle cramps, make up more calcium, rest and rest.

Arteries and blood vessels! What bugs! Arteries in the limbs and trunk are located in the muscles or deep areas, and veins are located in multiple epidermis.

If it's a bug.

You're not. I felt something squirm.

It is. I felt a huge pain.

It could be blood flow.

Sometimes it may be under a small muscle spasm.

Psychological effects, or your muscle spasms.

Lying down will press on the blood vessels, and the blood will cause a slight pressure in order to break through the resistance, and you will feel something squirming in your body.

Hospital: Orthopedics and internal medicine together.

If there is no problem, the "disease" will be cured after the examination.

Or you come here to consult:

Many people will have this feeling, that is, the blood in the blood vessels is flowing, and when the blood flows to the bend out, a certain impact occurs, which can only be felt when it is quiet. Sometimes it feels like the blood vessels are clogged or flowing slowly, and suddenly the blood flows very quickly.

...Transient absence of calcium salts.

Too low a concentration of Ca ions in the blood can cause muscle twitches, which can also cause transient nerve excitation, so.

Don't be afraid, eat two calcium tablets and drink some bone broth.

If it doesn't work, it's not a bug anyway, it's impossible.

Psychological effects, don't worry.

Besides, even if it's a bug, you won't go to a doctor?!Anyway, you can't die, what are you afraid of?

Parasite. There are fluffy breasts on the net, and there are locusts with grasshoppers in their noses.

Take care of the landlord.

It shouldn't be a parasite.

If it's a parasite, the feeling you call is that it's wriggling, then it's an adult. And the adult worm of the parasite should be in the digestive tract, how can it be in the muscles?

Psychological effects. Scare yourself yourself.

Just don't think about it.

I also think it's psychological.

Personally, I think it is caused by a slight muscle twitch after lying down for a long time.

Sometimes certain parts of the person move on their own.

Hehe..

Your muscles are spasming! Up tight! You can go to the doctor! Check it out! Good luck!

This is likely to be your psychological effect, muscle and nerve twitching is normal, and the human body is not static, maybe you are more sensitive, don't worry, as long as there is no physical discomfort, there is no big problem.

It is absolutely impossible to suspect the worm as you say, even if there is a parasite, his wriggling is not such a feeling as yours, you can't even feel it, only the onset of the disease has a feeling.

The report you see may be talking about a parasite. A beef tapeworm can grow from a fertilized egg to 2 meters in length in 10 weeks. And the infected person is initially unconscious. After a few weeks, it was found that the stool contained moving worm segments.

Mitochondria, chloroplasts. Because both of them contain DNA inside, they belong to semi-self-help organelles. Coupled with ribosomes, the base complementary pairing of t-RNA and mRNA takes place inside it.

1.Mitochondria: Mitochondria contain DNA, and when DNA is replicated, the pairing of bases A T, G C, T A, C G occurs; When DNA is transcribed into RNA, the pairing of bases A U, G C, T A, C G occurs; The pairing of bases A U, G C, U A, C G occurs when RNA is involved in translation.

2.Chloroplasts: Same as above.

3.Ribosome: The process of completing translation on a ribosome, the complementary pairing of bases A U, G C, U A, C G occurs between the base on the mRNA and the base on the tRNA.

In high school, the nucleus is not considered an organelle, so the answer is only the above three organelles).

Hello, this seems to be a college entrance examination question in a certain year.

1. AIDS is an infectious disease, and there is no comparison with cancer in terms of the incidence of disease, the first mistake;

2. Correct, nitrite does cause genetic mutations by changing the order of nucleic acids. Nitrite is a precursor to nitrosamine compounds. In nature, nitrite is easily combined with amination to form nitrosamines.

In the acidic environment of the human stomach, nitrite can also be converted to nitrosamines. In people's daily diet, most nitrite is excreted in the human body with urine like a "passerby", and it is only converted into nitrosamines under certain conditions. The so-called specific conditions include pH, microorganisms, and temperature.

Therefore, under normal conditions, nitrite in the diet will not cause harm to human health, only excessive intake of nitrite and lack of vitamin C in the body will cause harm to the human body. In addition, long-term consumption of foods with high nitrite content, or direct intake of foods containing nitrosamines, may induce cancer.

This carcinogen mainly increases the chance of genetic mutations that lead to the incidence of cancer.

A genetic mutation is a change in the sequence of DNA. Nitrite (caused by a genetic mutation in cancer) does induce cancer. Gene mutations originate from many internal and external factors, nitrite is a chemical factor in external factors, it can affect the transcription and replication of DNA, and then affect the spatial conformation of the protein molecule that the DNA guides the synthesis, so that the protein can not play its normal physiological functions, the body metabolic disorders, and the risk of cancer increases.

1. Incorrect AIDS is an infectious disease, which requires three conditions: the source of infection, the route of transmission and the susceptible population. In other words, without these three conditions, people will never get sick. Cancer is different. Genetic mutation organic rate.

2. Incorrect. Nitrite can oxidize the normal oxygen-carrying low hemoglobin in the blood to methemoglobin, thus losing the oxygen-carrying capacity and causing tissue hypoxia.

1 People with AIDS have the same chance of developing the disease, but the blame for death is greater than that of normal people. Because the HIV virus is the death of T cells in the human body. Unable to fight foreign antigens.

2 is not the variable gene structure. Nitrite is an industrial salt. There are also those that use sodium nitrite for food. Resulting in death by suffocation in the human body. Rather than changing the genetic structure.

1.Apical cells do not have large vacuoles.

2。I think it's for plant bodies.

3.If there is no cell differentiation, then the individual is just a cell clump. Only concentrated life activities can be performed.

1. If there is a vacuole, the concentration of the external solution is greater than the concentration in the vacuole, and the plasmo-wall separation will inevitably occur. 2 is wrong, the degree of differentiation of egg cells is not high. 3 is false, such as paramecium, which is a single-celled organism in which the individual develops but does not differentiate.
