High School Biology Answer C but why is B right? The actual length of each small cell remains the sa

When the microscope magnification is turned up, the cells are magnified, but the micrometer is not magnified, and this thing is on the lens.

Therefore, the length of each compartment on the micrometer is fixed and independent of the magnification of the microscope.

The "actual length" is the true value of the micrometer, which is constant.

"Length" is the cell size measured by the micrometer, which varies according to the magnification of the microscope.

For example, if you magnify a cell 10 times, the length of a cell will become 10 blocks.

In other words, if you zoom in 10 times, 1 cell represents 1 10 cells of a cell length.

Therefore, when the magnification of the microscope is increased, the length represented by the micrometer becomes smaller.

I know what your question is.,That question is too classic.,Item A doesn't say to turn the eyepiece or something.,B says the length of each cell on the micrometer.。。 (forgot). Item c is easy to explain that the length represented by the micrometer is smaller because the multiplier is larger.

The micrometer reagent is so long, the original measurement of 2cm (a grid represents 2cm), as soon as the cell becomes larger, the length measured by a small grid is smaller, and now the ruler represents only 1cm.

First of all, there must be only X from the mother, because the mother must give and can only give X, and Y is only available to the father, so the mother gave X, and the father gave Yy to have two Ys, which can only be secondary spermatocytes, and if it is a primary spermatocyte, it should be the father who gave xy.

First of all, there are two cases of xyy, it is possible to be x and yy or xy and y, the latter is obviously not possible. So only possible x and yy

Well, the mother must be normal. If there is a problem with the father subtracting one, then xy does not match the question.

Therefore it can only be c

Hello! Because the length can be different, the annealing temperature is not only related to the GC content, but also to the length of the sequence.

Determine the direction of the translation, and look at which side of the peptide chain is longer and which side is shorter. The longer the translation time, the longer the peptide chain, in the direction from the short peptide chain to the long peptide chain. C, the time of 1b is determined by one ribosome, but the simultaneous operation of multiple ribosomes makes the time to synthesize multiple bs short.

The binding of multiple ribosomes on a single mRNA increases the amount of protein synthesized per unit of time, but does not shorten the time it takes to synthesize each polypeptide chain.

So C is wrong.

It's made from short to long, and the long one in the diagram translates first than the short one, and you can see that the ribosomes go through the long chain first, and they just reach the short chain.

Just like your puzzle, one person is responsible for one piece, and then it is put together into large pieces, and just like that, a bunch of ribosomes are responsible for the part of the amino acids, which is the polypeptide, and then it is handed over to the endoplasmic reticulum piece, and then the Golgi apparatus is put together.

First of all, it is certain that C is wrong, and after the enzyme is inactivated, the substrate is added, and the final product does not increase. That is to say, the total amount of the final product is constant, if you consider that after adding 2 times the substrate, the volume of the total system increases, but the total amount of the final product does not change, so the concentration of the product will be smaller, that is, it will be diluted.

The total amount remains the same, the volume becomes larger, and the concentration becomes smaller.
