It's a probability, right?
Definition of probability].
A measure of the likelihood of a random event occurring. One of the most fundamental concepts of probability theory. It is often said that there is a percentage certainty that someone will pass the test and what is the probability that something will happen, these are examples of probability.
Method of Calculating Probability].
a Calculated using the classical formula: probability = (number of combinations of a genotype or phenotype Total number of combinations) 100%.
For example, if the total number of combinations is 4, the number of combinations of a trait is 3, and the number of albinos is 1, and the probability calculation formula can be substituted to obtain 4.

Biological value of protein: It refers to the part of the protein that can be stored and utilized by the body after digestion and absorption, which can be measured by nitrogen storage method.
The closer the ratio of essential amino acids of a food protein to the ratio of essential amino acids required by the human body, the higher the biological value of the food protein. By eating coarse grains and fine grains, meat and vegetarian foods, it can play a complementary role in protein, which is more conducive to health.

Protein can express the traits of living organisms and is the embodiment of life activities.

In fact, biology is still in the stage of development in China! And in biology, it's better to have a graduate diploma, so it's easier to find a job! If the experiment is done well, there are still many companies that want this major, after all, it still belongs to scientific research!
You can go to a pharmaceutical factory, a food factory, etc.!

I still have to go to graduate school, and I think this major has no future if I don't go to graduate school.

Don't listen to the official version of the professional introduction, those are the official clichés of the country's strategic layout, and listen to the blood and tears of countless biological predecessors who have defied the law. Cheap is not good, good goods are not cheap, the postdoctoral fellows, doctors and masters trained in biology are several times that of other majors, becoming the major that cultivates the most highly educated talents, and the research rate of biology is also the highest compared to other majors, and it is the easiest to go abroad, because it requires a large number of cheap labor of biological migrant workers, and the pie that falls from the sky must not be picked up. Life sciences, also known as biology majors, which used to have the highest admission scores in the college entrance examination, have now become the most unpopular and unpopular majors with the worst employment situation (there is no one), doesn't it still explain the problem?
After studying biology, the time cost you spend is several times that of any other major, and when you see that the salary of third-rate undergraduate or junior college students studying finance, IT, accounting, computer science, civil engineering and architecture is several times that of doctoral students in key universities, do you still have hope for this major? How many people really rely on insisting on reading a lot of good articles after reading a n-year doctorate? If you can't make it to that day and choose a job halfway, what awaits you is low salary, poverty, and boring repetitive experiments, ** The hyped biomedical breakthrough in full swing is based on the negative results of hundreds of thousands of millions of biological migrant workers who have failed countless times for decades, and the base of highly educated migrant workers in biology is too large, and there are still others to try and make mistakes for you.
Any biological company is piled up with dozens of biology doctors and hundreds of biology masters, and the masters and doctors are valuable, but with the word biology in front of them, it is not valuable. That's the sad thing about biological people.

Biomedical engineering is an engineering major with the highest percentage of female students. The advantage of this major is that you can go to medical school or pharmacy school, and you can find a job with a good salary after graduating from undergraduate. Two of the best universities for biomedical engineering should be Johns Hopkins University and UC San Diago.
In addition, the biomedical engineering profession is noble in its mission to save lives and benefit mankind. It's not like when I was studying for a doctorate in the United States, doing preliminary work on nuclear process simulation.

Darwin's theory of natural selection was very influential, and before Darwin, Lamarck proposed the theory of biological evolution, arguing that "1 living things evolved from older organisms; 2. Organisms gradually evolved from the lower to the higher; 3. Advance, waste and acquired heredity".
Darwin's theory of natural selection was based on Lamarck's theory of biological evolution, plus what he saw and heard in the voyage, and analyzed and synthesized it. There are some parts that are the same between the two. However, Darwin's theory of evolution also has some shortcomings, for example, he studied evolution in terms of the individual, but the modern theory of biological evolution believes that the unit of biological evolution is"Population"At the same time, because when Darwin proposed the theory of natural selection, biotechnology had not yet been able to accurately understand the molecular basis of "genes" and "variations", so Darwin's description was mostly limited to the trait level.
Subsequently, the modern theory of biological evolution has been based on the development of mathematical models, biochemistry and other disciplines, and has made new progress. When describing the population, Hardweinberg envisioned a purely theoretical situation and demonstrated it, resulting in the "Hardweinberg equilibrium", or Harwinberg equilibrium, which was mathematically demonstrated. In addition, the development of molecular biology has given mankind a new understanding of the nature of genes, heredity and variation.
Belief that genetic mutations are the root cause of the emergence of new alleles (manifested in traits), and so on.

I am a student of Biomedical Engineering, Faculty of Electrical Engineering and Automation. When I was a freshman, I studied about the same as everyone else, and in my sophomore year, I learned a lot about anatomy and engineering electromagnetic fields. The third year is basically a professional course, and in the first half of the semester, students study biomedical electronics, microcomputer, physiology, sensors, automatic control principles, and professional English.
In the second half of the semester, I will learn signal and system, digital signal processing, image processing, medical electronic instrument processing, database, electronic power technology, and two more that I can't remember. I have to go out for internships and so on in my senior year, which is more annoying. Learning is definitely the most, learning well is definitely the hardest, and you must be mentally prepared.
Because there are partial doctors and partial workers in this profession, take me as an example, you can go out to work and enter the hospital as a technician, or grab a job with electrical appliances, go to the power company, especially the State Grid, you can work hard, and you can go to Shanghai, Hangzhou, Beijing, Shenzhen, go abroad to join some medical instrument companies, whether you can enter depends on your ability, the salary is absolutely high. You don't want to be fooled by online people, as long as you have a high score, you can't get in. Biomedical engineering is the widest and has the greatest room for manoeuvre.
I really can't find a job, so it's a big deal to work hard, learn more, and grab jobs with other majors. Be optimistic!!

Medical devices, bioinformatics, image processing.
Most of them are engaged in medical device sales, or after-sales and technical support.
Biological science refers to the discipline system that studies life activities and their development laws, including molecular biology, physiology, ecology, genetics and other disciplines. Biological science is the exploration and application of biology, involving the development and utilization of biological resources, the development of diseases, the research and development of new drugs for digital difficulties, and environmental protection. There is an inseparable relationship between the two. >>>More
