What did ancient scientist Zhang Heng invent? The explanation should be complete
How to complete the seismograph
There are a lot of online search, why don't you like to find the answer by yourself?
What did Cai Lun, Watt and Bi Sheng invent respectively
The problem is inaccurate
But I know the answer you want
Cai Lun improved papermaking in the Eastern Han Dynasty (the earliest paper in China was discovered in the early Western Han Dynasty)
Watt improved the steam engine instead of inventing it
Bi Sheng of the Northern Song Dynasty invented movable type printing
What do we learn from the story of Cai Lun and Bi Sheng?
We should be good at summing up the experience of our predecessors and work hard. Even if we have some now, we can improve them. They will become better. Of course, we should not stick to the rules but innovate
Who invented what (what is the correct answer?) Cai Lun papermaking Bisheng seismograph Zhang Heng printing watt steam engine
Who else invented what
Answer like this:
Edison invented the electric light
Cai Lun invented papermaking
Bi Sheng invented printing
Zhang Heng invented the seismograph
Watt invented the steam engine

- 18. On Mendelian genetics The color of a plant flower is regulated by two pairs of non allelic genes a (a) and B (b). Gene a controls the synthesis of pigment (A: the appearance of pigment, AA and AA have the same effect), and gene B is the modifying gene, which weakens the depth of color (B: the appearance of modifying effect, BB and BB have different effects). F1 is obtained by crossing P1 (AABB, white) with P2 (AABB, red), The results show that F2 is red, pink and white, and their ratio is 3:6:7_________ (2) if haploid breeding was carried out on pink F1 plants, the phenotype and proportion of flower color of the plants were different_________ (3) what are the genotypes of white flower in F2?
