1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.
2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.
3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.
4. The centromeres are moved towards the poles of the cell at prophase II stage.
Answer:
Some viruses are hard to treat because sometimes it’s not the virus that makes us sick; it’s our immune system.
Explanation:
Explanation:
we all find ourselves confronted with the age-old question:
what happens when you fall into a black hole?
You might expect to get crushed, or maybe torn to pieces. But the reality is stranger than that.
The instant you entered the black hole, reality would split in two. In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed.
Hope this helps you.. Good Luck
The appropriate answer is c. a scientific journal. A scientific journal is a collection of papers based on topics in science that have been written by experts in their fields. Individuals with a masters or doctorate in various subject areas are published here.
From the list given this is the best second source for the research. Science fiction novels and not real and so would be unacceptable. Magazines and news papers reporting on scientific research most likely get information from scientific journals.
