Metaphase - I is marked by the breakdown of the nuclear membrane and the attachment of kinetochore microtubules to the bivalent. Homologus pair moves together along the metaphase plate.

230940 Above diagram represents
1 anaphase-I
2 metaphase-I
3 telophase-I
4 prophase-I
Explanation:
Anaphase - I homologus chromosomes are separated. In this phase, sister chromatids stay together. Homologus chromosomes separated and move to opposite poles.

Biogas production is carried out by
1 thermoacidophils
2 methanogens
3 halophiles
4 ruminants
Explanation:
B Biogas production is carried out by methanogen. Biogas production involved mainly four stepes ; - Hydrolysis Amino acid, sugar alcohol, fatty acid Acidogenesis Intermediary products (volatile fatty acids. acetate, Propionate, ethanol , lactate.

Statement (S) Non-disjunction is the failure of paired chromosomes to segregate during the metaphase of meiotic divisions of gametogenesis. Reason (R) Non-disjunction results in production of abnormal gametes. The correct answer is
1 Both \(\mathrm{S}\) and \(\mathrm{r}\) are true, and \(\mathrm{R}\) is not a correct explanation to \(S\)
2 \(\mathrm{S}\) is correct, but \(\mathrm{R}\) is not correct
3 \(\mathrm{S}\) is not correct, but \(\mathrm{R}\) is correct
4 Both \(\mathrm{S}\) and \(\mathrm{R}\) are true, and \(\mathrm{R}\) is a correct explanation to \(S\)
Explanation:
D Non disjunction is the failure of homologous chromosomes or sister chromatids to separate during cell division. Failure of a pair of homologous chromosomes to separate in meiosis - I . Non disjunction results in daughter cells with abnormal chromosomes numbers.
