Biology questions are for detailed explanations, and biology problems for experts to solve in detail

Genna Green is a reactive dye, and it can only be dyed with Genna Green if it remains active.

Select CA, Sudan Destroy cell permeability.

b. The permeability of the cells can be stained after the permeability of the cells is destroyed with hydrochloric acid.

c. Specific stain for living cells.

d. Same as b.

c At the high school level, only Genna Green is a live cell dye.

Choose C, Genna Green as the reactive dye.

c Sucrose and protein. The first is the N form of the carbohydrate CN(H2O1), and C1864H3012N168O221 contains the N element, which is specific to proteins.

b Nucleus Ribosomes and the Golgi apparatus Uridine is needed for the synthesis of proteins, whereas ribosomes and the Golgi apparatus are the sites for the synthesis of proteins.

c Sucrose and protein.

b Nucleus ribosomes and Golgi apparatus.

1 Because it is completely hydrolyzed, it is not the consumption of 1 molecule of water (the specific amount is not required to be mastered, anyway, it is not 1, there is a talk in Pusheng) Wrong.

2. False: It is generally believed that the quality of heat energy is low and cannot be converted, and there is a serious error in this sub-question: "Converted into ATP in cells".

Note that it is "energy to ATP" ATP is matter. How can it be said that energy is converted into matter?

Please note this, often take the test. Such as the light reaction converts solar energy to ATP error.

3 Correct Oxygen first passes through the red blood cell membrane (one layer) and then through a layer of blood vessels into the interstitial fluid (one layer of blood vessels is a layer of cells, through one layer of cells, through two layers of biofilm), before entering liver cells, it passes through another layer of biofilm, and then into the mitochondria, and two layers.

So 6 floors. 4 Error Paper chromatography is used for separation, not extraction.

5 Error The unwinding of genetic material is the unwinding of DNA, but the gradual recovery of chromosomes into chromatin is chromosome unwinding, chromosome unwinding is the transformation of chromosomes into elongated filamentous chromatin, and DNA unwinding is unwinding of the double helix structure.

Please note: DNA is a double helix, while chromosomes are supercoiled on top of this.

So you can know that the unwinding of DNA is the unwinding of the double helix, whereas the unwinding of chromosomes is the unwinding of supercoils. These two concepts are not the same.

6 Error This one is easy.

It's not easy to get extra points...

Choose A, you should know the efficiency of energy transfer, about 10% to 20%, when a creature fixes (assimilates) the previous trophic level, the energy obtained is only about 10% to 20%, and if another organism uses this creature as food, then the energy it gets is 10% to 20% after the assimilation of this creature, that is, once more squared, less and less energy, so this question chooses A

1. Plant cells are usually ethanol pathways, and a few can also produce lactic acid.

2. The respiratory chain in the mitochondria is mainly located on the specialized crest of the inner membrane, and the protein content is naturally higher than that of the outer membrane.

3. Chlorophyll a b

4. Dark color, I can't tell what color it is in that background 5. It must be developed. The endoplasmic reticulum is divided into two types: smooth and rough, the rough endoplasmic reticulum is attached to ribosomes, which mainly synthesize proteins, and the smooth endoplasmic reticulum mainly synthesizes lipids, including sterol hormones.

6. Yes, this is the transport of membrane vesicles in the cell, which is mainly completed by membranous organelles, including endoplasmic reticulum, Golgi apparatus, lysosomes, and endosomes.

7. The mistake lies in the allele. Remember that alleles are defined as different genes in the same position on homologous chromosomes. Therefore, the statement in the question is incorrect, and the correct one should be the separation of homologous chromosomes and the free combination of non-homologous chromosomes.

1.Anaerobic respiration of plant cells is the production of alcohol and CO2 [animal potato tubers beet tubers lactic acid bacteria produce lactic acid by anaerobic respiration].

2.Enzymes involved in aerobic respiration are attached to the inner membrane.

3..Chlorophyll.

4.We're just talking about dyeing dark.

5.It is developed because the endoplasmic reticulum is involved in the synthesis and secretion of sterol hormones.

6.Probably right.

7.Plus the premise is that the non-allelic genes on the non-homologous chromosomes can't be freely combined, I don't know if it can help you, I'm a student, and I don't know if it's right

The answer is caBlood sugar regulation mainly depends on the islets of pancreas, of course, the hypothalamus has a regulatory role, but the removal of the hypothalamus will only be affected!

b.The higher nerve center is, of course, the cerebral cortex!

d.Congenital behavior also has to involve the nervous system, reflex!
