1. Biosphere.

Including the atmosphere.

The bottom, most of the hydrosphere and the lithosphere surface.

2. The environmental factors that affect the life of living organisms can be divided into two categories: biological factors and abiotic factors (light, temperature, water, etc.).

3. Adaptation and influence of organisms to the environment: Organisms constantly adapt to the environment and influence and change the environment in the process of survival and development.

4. Ecosystem.

The composition includes the biological and abiotic parts, where the biological part includes producers, consumers and decomposers; Abiotic parts such as sunlight, air, water, etc.

5. The relationship between producers and consumers is mainly the relationship between eating and being eaten, so that the food chain is formed.

The food chains are intertwined with each other to form a food web. Matter and energy in ecosystems flow along the food chain and food web, however, harmful substances such as pesticides are increasing step by step.

6. Steps for using the microscope: taking and placing the lens, aligning the light, observing, cleaning and closing the lens.

7. What the eyepiece sees is an inverted image; The magnification of a microscope is the product of the magnification of the objective lens and the eyepiece. For example: 10x30=300.

8. If you see the image in the field of view to the lower left, the specimen should move the image to the lower left to move to **; The specimen moves upwards to the right, and the object seen in the field of view moves towards the lower left.

9. Onion scale leaf epidermal cell temporary loading production: preparation (wipe clean, drip water); Production (peeling off the inner epidermis, flattening; coverslips); Dyeing (dripping iodine solution, absorbent paper suction).

10. Temporary loading of human oral epithelial cells: preparation (wipe clean, drip normal saline); Preparation (a few scrapes, smearing; coverslips); Dyeing (dripping iodine solution, absorbent paper suction).

Never before in history has a book been so violently reviled and cursed, nor has there ever been a book that has been so enthusiastically applauded and sought after at the same time. Darwin's great ideas used to be a joke, but now they are the consensus. The huge impact of On the Origin of Species goes far beyond the life sciences themselves, already.

2.Morgan's "Theory of Genes" Recommendation: "Theory of Genes" is the most important theoretical work in the history of classical genetics, and the author Morgan is a representative of the Mendel-Morgan school and winner of the Nobel Prize in Physiology or Medicine in 1933.

The Theory of Genes is a comprehensive exposition of Morgan's theory of genes (theory of chromosomal inheritance), which includes genetics.
