Reasons for the decrease in the number of BS combustion pits

1. The width of the central main stage is twice that of the wavelength divided by the slit width. As the slit width increases, the main stage becomes narrower. The width of the interference fringes is determined by the slit spacing. The slit spacing does not change, so the width of the interference fringes does not change. However, as the width of the main stage increases, the number of interference fringes increases

2. Before that, the Ministry of information instry of China had organized a network resource inspection, which was specially aimed at the network video business website. If any unqualified video was found, the website would be ordered to rectify. Otherwise, the Internet video information dissemination license would not be issued, and Tudou would suffer this loss, The Ministry of information instry did not issue "Internet video information dissemination license" to the first batch of approved websites, so since then, as long as it is a little famous video website, those unqualified videos have been deleted, otherwise the Ministry of information instry will not issue the license, the website can no longer do

this, no, these are deleted by the website itself, Maybe it doesn't conform to the regulations of the Ministry of information instry in some aspects. Maybe the website has deleted some outdated contents. I'm just guessing

3. Does a small amount of carbon completely burn with oxygen in a sealed gas collecting cylinder and the number of gas molecules in the cylinder remains unchanged?
A. when determining the volume fraction of oxygen in air, the remaining gas is about
4
5
. So a is wrong
B. the proct of carbon combustion is carbon dioxide, which contains resial gas, and the mass of the gas is not zero
C. when a small amount of HGO powder is heated in a closed container, the quality of oxygen remains unchanged< The mass ratio of hydrogen to oxygen is 1:8, so D is wrong

4. If the number of chromosomes changes, usually one chromosome breaks and becomes two; Or two chromosomes fuse into a new one. These newly generated chromosomes must have the three characteristics mentioned above. It's easier to say the starting point of replication, because usually there are hundreds to thousands of copies on a chromosome. Telomere structure and separation center are more headache. In particular, the separation center, each chromosome can only have one activity, otherwise this chromosome will be broken. Moreover, the sequence of the separation center is hundreds of thousands or even tens of thousands of nucleotides, which is not a small number and cannot be generated spontaneously. Even if it happens by accident, its activity must be inhibited by some mechanism. The number of telomeres must be twice as many as the number of chromosomes. There are strict methods in cells.

5. There may be two reasons for the decrease of payment amount:
1. Your payment base has decreased
2. The personal account of the old-age insurance of the former insured includes: the part of indivial payment and the part of unit overall planning according to the national regulations. Now, according to the social insurance law of the people's Republic of China, from July, all the part of the unit has been transferred into the overall planning fund and no longer into the personal account. Therefore, the part of unit overall planning has been reced in the personal old-age insurance account, The number is less than before.

6. The number of mitotic and non mitotic chromosomes remained unchanged, while the number of meiotic chromosomes was halved
