The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.
In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
Well the divergent boundary, occurs most often at mid-oceanic ridges. Here, two plates move away from each other, forming a break, or rift, in Earth's crust. Magma from the mantle rises to fill the gap, creating new crust.

Answer:
The correct answer is C) selective transport through nuclear pore complexes
Explanation:
Nucleus is the place where the replication and the transcription of DNA occurs. The process of translation in eukaryotes occurs in cytoplasm therefore RNA has to come out of the nucleus.
Nuclear pore complexes are the openings in the nuclear membrane from where these molecules come out in the cytoplasm. Small RNA like tRNA directly comes out through binding directly to export receptors but large RNA like mRNA forms ribonucleoprotein particles which involves class-specific adaptor proteins for transport. So the right answer is C.
Organisms need cell division to survive and multiply. The main goal of cell division is to make more cells. For example, most of the cells in the human body are somatic cells and divide regularly. This cell and tissue turnover is important for the organism's health and growth.
