Bivalents的音标是["baɪvə"leɪts],意思是双价染色体。要记住这个单词,可以尝试将其拆分为“bi”(双)和“valent”(有价值的),以形成联想记忆。此外,可以了解双价染色体在生物学中的意义,从而更好地理解这个单词的含义。
Bivalents的英文词源是拉丁语的“bi”(意为“两个”)和“valens”(意为“强壮的,健康的”)。
变化形式:复数形式为bivalents。
相关单词:
1. Diploid:双倍体,由两个相同染色体组成的染色体组。
2. Haploid:单倍体,由一个染色体组组成的染色体组。
3. Monoecious:单性花,一种植物的花朵只有雄性或雌性。
4. Polyploid:多倍体,由多个染色体组组成的染色体组。
5. Bipolar:两极的,指电或磁场的两极。

英文小作文:
Bivalents play a crucial role in biology and genetics, as they are responsible for the proper segregation of chromosomes during meiosis, which is crucial for the production of healthy offspring. However, bivalents can also be associated with genetic disorders and diseases, making them an interesting topic of research for geneticists and biologists. In this essay, I will explore the importance of bivalents and their role in biology and genetics, as well as discuss some of the challenges that they pose for researchers. I hope that this essay will shed light on the fascinating world of bivalents and inspire future generations of researchers to explore this topic further.
