To answer the questions, let's break down each question and its options:
1. Dis what a Centromers Membrane?
I'm sorry, but I'm not sure what "Centromers Membrane" refers to. It could be a term you're requesting information on or a typo. Could you please provide more context or clarify the term?
2. The pinching off of the ces membrane mat creates two new ces terres
This statement seems to have typos, making it difficult to understand. Could you please clarify what you mean or correct any errors?
3. All 10 chromosomes undergoes missis, How many doughter cels are created daughter cell has chromosomes?
It seems like there are some inaccuracies in the question. It's not clear what "missis" refers to, and the answer options are not provided. Could you please provide more information?
4. 18 The cell cycle [...] cis different langms of time for offset types of cells.
This statement is not clear and contains typos. Could you please clarify what you mean or correct any errors?
5. 19. What is the primary purpose of meiosis o. To produce genetically identical cells
b. To produce gametes (sex cells)
d. has ending
c. To repair damaged cels
The primary purpose of meiosis is to produce gametes (sex cells). The correct answer is b. To produce gametes (sex cells).
6. 20. What is the significance of crossing over a. It reduces genetic diversity.
b. It ensures that homologous chromosomes separate properly.
c. It increases genetic diversity by swapping alleles between homologous chromosomes.
Crossing over during meiosis is significant because it increases genetic diversity by swapping alleles between homologous chromosomes. The correct answer is c. It increases genetic diversity by swapping alleles between homologous chromosomes.
7. A 21. Which genetic disorder results from an extra chromosome 213
a. Down syndrome
b. Turner syndrome
c. Klinefelter syndrome
d. Cystic fibrosis
The genetic disorder that results from an extra chromosome 21 is Down syndrome. The correct answer is a. Down syndrome.
8. 22. How does non-disjunction during meiosis lead to genetic disorders?
c. It prevents the formation of gametes.
a. It creates genetic diversity.
b. It results in extra or missing chromosomes in offspring.
d. It increases the number of crossover events.
Non-disjunction during meiosis can lead to genetic disorders by resulting in extra or missing chromosomes in offspring. The correct answer is b. It results in extra or missing chromosomes in offspring.
9. 23. How does sexual reproduction, including melosis, contribute to the process of evolution?
a. By reducing genetic diversity
b. By preventing the formation of offspring
d. By eliminating mutations
c. By increasing genetic diversity, allowing for adaptation to changing environments
Sexual reproduction, including meiosis, contributes to the process of evolution by increasing genetic diversity, allowing for adaptation to changing environments. The correct answer is c. By increasing genetic diversity, allowing for adaptation to changing environments.
10. A 24. During which phase of meiosis does homologous chromosome pairing and crossing over occur?
a. Prophase I
c. Anaphase
b. Metaphase I
d. Telophase
Homologous chromosome pairing and crossing over occur during Prophase I of meiosis. The correct answer is a. Prophase I.
11. 25. What is the end result of meiosis in terms of the number of daughter cells produced?
a) Two diploid cells
b) Two haploid cells
The end result of meiosis is the production of two haploid cells. The correct answer is b) Two haploid cells.
