Biology fill in the blank questions, fill in the blank questions about creatures

The Forest Law of the People's Republic of China, the Grassland Law of the People's Republic of China, afforestation, returning farmland to grassland, and the road of sustainable development.

One. Fill-in-the-blank questions.

1.On the vast surface of the earth, the terrain is complex and diverse, and the climate varies greatly from place to place. Adapting to various environmental conditions, the species of organisms vary greatly from place to place, so there are many ecosystems in the biosphere, please name two of them.

As; wetland ecosystems; Forest ecosystems.

2.If the fish is fished out of the pond, it will not take long for it to die, which indicates that the fish need water for life If the algae and other bait in the pond are greatly reduced, the fish will also die, which indicates that the fish need food for life If there are too many fish in the pond, it will also cause some fish to die, which indicates that the fish need a certain space for life

3.The various factors in the environment that affect the life of living organisms are called the living environment and it is divided into biotic factors and abiotic factors.

4.Living organisms cannot survive without the environment. Kelp is suitable for growing in seawater, red-crowned cranes are suitable for inhabiting wetlands, cacti are often found in deserts, and cheetahs run in grasslands

5.Green plants are manufactured through photosynthesis"Food'', the animal inhales aerobic respiration and excretes carbon dioxide, urine and CO2 these phenomena are metabolic

Forest Law of the People's Republic of China, Grassland Law of the People's Republic of China, and the road to sustainable development.

1. Liquidity;

2, 2 and 3, to maintain the effective operation of respiration;

3. Assist in diffusion;

4. Ribosomes, ribosomes, enhanced.

Personal opinion, I hope to help you answer your questions

1. The basic characteristics of living things: 1. It has a common (material) basis and (structure) basis.

2. Able to breathe.

3. Have (irritable).

4. There are (growth and development) and (reproduction) phenomena.

5. There are (hereditary) and mutated characteristics.

6. Can (change) a certain environment, but also (adapt) to a certain environment.

2. Organization: The basic structure composed of the interstitium of the nucleus and the cell with similar (structure) and the same (function).

3. Distinguish the following types of living systems: 1 a lactic acid bacterium 2 lactic acid bacteria colonies in a petri dish; 3. After the medium is contaminated, in addition to lactic acid bacteria, fungi and other bacteria such as Escherichia coli are bred; 4 All ingredients in the Petri dish.

What structural level does each belong to a living system?

Populations, communities, ecosystems.

2) Connect them from micro to macro with arrows?

3) 1. It is the (cell) level and the (individual) level, but it does not have the level of (tissue), organ), system and other living systems.

Cell, Relevance, Information Molecules, Peptides, Amino Acids, Carbon Drop, Water, Ammonia, Nucleotides, Five Carbon Sugars, Phosphate Groups, Chromosomes, Chromatin, Chromatin, Chromatin, Color

5*10=50

The magnification of the microscope is equal to the magnification of the objective multiplied by the magnification of the eyepiece.

If you have any questions, you can call me. Hope it helps.

That's 50 times. Because the magnification of the microscope is equal to the magnification of the eyepiece multiplied by the magnification of the objective.

Magnification of the object = eyepiece * objective.

So, the eyepiece is marked with "5x."", engraved on the objective"10x", the object is magnified by a factor of 50;

Lactic acid bacteria decompose organic matter to form lactic acid, which requires an oxygen-free environment.

Symbiosis: 1 leguminous and rhizobia.

2 fungi and algae.

3 people and intestinal bacteria.

Most bacteria and fungi live saprophytes and are decomposers of ecosystems, while some species absorb nutrients from living animals and the human body and live parasiticly.

Types of fungi: In junior high school, you need to know that fungi include yeast, molds (such as Penicillium and Aspergillus), and macrofungi (such as mushrooms, Ganoderma lucidum, etc.).

Embryonic development, conduction, contraction, secretion, transport of oxygen.

Forget about the kind.

My standards.
