Junior 2 Biology Questions. Biology questions in the second year of junior high school

False )1The smaller the taxonomic unit, the fewer species it contains, and the fewer common features.

False )2The individuals of microorganisms are tiny, so they are all single-celled organisms.

No solution) 3Angiosperms account for 90% of the photosynthetic efficiency of global green plants.

No solution )4Indicator plants that can monitor sulphur dioxide pollution in the air are bryophytes.

right) 5The binomial method of naming plants was created by the Swedish scientist Linnaeus.

False) 6Animals that can live both in water and on land are amphibians.

Forgot )7Viruses cannot live independently, and can only carry out life activities if they are parasitic inside the host cell.

False )8Biological diversity and adaptability are the result of artificial selection.

Right) 9Under the conditions of suitable temperature, oxygen and nutrients, yeast can multiply rapidly in the form of germination.

10The cradle of life is the ocean.

1. Wrong: There should be more common features.

2. Mistakes: Some microorganisms do not have a cell structure, such as viruses;

Some microorganisms may also have multiple cells, such as some.

Fungi. 3. The wrong ratio is wrong, 90% should be tropical forests.

Plant. 4. Right.

5. Right. 6. Mistakes like penguins.

7. Right. 8. Error is the result of natural selection.

9. Yeast should only enter under poor conditions.

Sexual reproduction.

10. Right.

1.False: If the classification is based on "species" and "genus", there should be more common characteristics.

2.False Definition of microorganisms: A general term for all tiny organisms that are invisible or inaudible to the naked eye in the microbiology room.

These include actinomycetes, cyanobacteria, mycoplasma, chlamydia, rickettsia, and chlamydia belonging to the prokaryotic group of bacteria (eubacteria, archaea); belonging to eukaryotic fungi (yeasts, molds and mushrooms), protozoa and microscopic algae; Viruses and subviruses that belong to the non-cellular class (viroids, mimetrics, and prions).

3.False Marine algae are the strongest and most extensive in photosynthesis.

6.False Reference.

7.Right. 8.Wrong Natural selection.

9.Right. 10.Right.

1.False: The more common features there are.

2.Wrong Not exactly, some don't have cellular structures like viruses.

3.False: 90% should be tropical forest plants.

4.For mosses there is only one layer of cells on the surface of the moss and sulphur dioxide pollution kills it.

5.Yes is Linnaeus; However, the binomial method is to name all species.

6.Wrong like a penguin.

7.For cell-free structures.

8.Wrong Natural selection.

9.10Right.

1.False: The more common features there are.

2.Wrong Not exactly, some have no cellular structure.

4.Wrong lichens.

5.Right. 6.Wrong like a penguin.

7.Right. 8.Wrong natural selection talent comes out for a few years.

9.Right. 10.Right.

··· Wrong, wrong, right, right, wrong, right, right.

6CB fill-in-the-blank is not accurate, I don't want to mislead you,

1. The front end of the earthworm has a ring band (reproductive belt).

2. The back is shallow and the ventral surface is deep, with less back hair and more abdominal hair.

3. The volume of air in the soil is occupied by rain, and there is no air in the soil for earthworms to come out to breathe.

At the anterior end there is a segmented inconspicuous annular band. The ventral surface is lighter in color, and most body segments have bristles in the middle, which act as a fixed support when the earthworm crawls. After the 11 segments, there are dorsal holes at the dorsal line of each segment, which is conducive to breathing and keeps the body moist.

So on a rainy day, you have to come out to breathe or drown.
