Hello, no one has seen your question for a long time, but no one will be deducted points and your bounty points will be forfeited if the question expires! So I'll give you a few suggestions:

1. Ask questions as completely and clearly as possible, do not have obscure words, you don't know your situation at all, if your question is not clear, you don't know what you are talking about, you can't talk about your problem.

2. Don't ask a lot of the same questions at one time when asking questions, asking the same questions makes people look very stressed and annoyed, and even think that you are cheating. Therefore, it is enough to ask a question once and be concise.

3. The questioner should respect the person, others are not your slaves and must solve the problem for you, so please pay attention to civilized language when asking questions! Respect the labor of others.

4. Don't ask too simple questions, don't ask them knowingly, it's a waste of precious time! And don't ask questions about alleged violations.

5. Don't get involved in cutting-edge science.

It's just ordinary people, and if you ask a question that even scientists don't have an answer to, it's hard to ask the answer here.

6. You can make more knowledgeable netizens, some of the more difficult questions in the past, if someone is right, you can become good friends with them, and often keep in touch.

The second volume of the eighth grade of biology is reviewed in the human education version.

1 The phrase "sow beans and get beans, sow melons and get melons" illustrates the hereditary nature of living things. "No two leaves in the world are exactly the same," the phrase illustrates the variability of living things.

2 Due to the different environments, some primitive life evolved into primitive plants with photosynthesis (autotrophics), and the other evolved into primitive animals without photosynthesis (unable to autotroph). These primitive organisms evolved into a wide variety of plants and animals, respectively.

3 Comparing fossils in different strata, the older the strata, the simpler and more singular the organisms that became fossils, and the more fossils of aquatic organisms; And the more recent the strata, the more complex and diverse the organisms that became fossils, and the more fossilized terrestrial organisms became. This shows that organisms have evolved from simple to complex, single to diverse, and aquatic to terrestrial. In addition, scientists have found that there are no fossils in the oldest strata, indicating that the earth was formed before the formation of living things.

1 Biological classification is mainly to divide organisms into different levels such as (species) and (genus) according to the (degree of similarity) of organisms, and scientifically describe the characteristics of each taxa (morphological structure) to clarify the (kinship) and (evolutionary) relationship between different taxa.

2 When biologists classify angiosperms, they often use (flowers), (fruits), and (seeds) as important bases for classification.

3 In addition to the external morphological structure, animal classification often requires a comparison of the internal structure and (physiological function) of the animal.
