Solved Exercises 2nd Year Biology Cell Division:
If you want to understand cell division better, you should learn about its phases. Mitosis has three stages: the prophase, the metaphase, and the anaphase. Learn cell division’s phases to better comprehend it.
Prophase, metaphase, and anaphase comprise mitosis. During prophase, chromosomes’ center point in preparation split. During metaphase and anaphase. Each chromosome can segregate into chromatids after anaphase.
Karyokinesis and Mitosis are 2nd-year syllabus terms. Here are some of their process. All readers can grasp the explanation below. Karyokinesis: During Meiosis (cell division), homologous chromosomes travel to opposite poles. Anaphase 1 disjunction yields two daughter cells. Sister chromatids adhere to spindle fibers at the centromere during Metaphase 1. (1A) and migrate towards the metaphase plate in anaphase.
Example Questions Biology:
Animal body fluids are isotonic to the animals whose body fluids are the external environment. Even concentrations differ noticeably from the marine saltwater environment.
This outside environment actively regulates animals. And thus does not require action to discharge excess water in hypotonic adjust their internal osmotic state. Why does filtration takes place only at the glomeruli part of the nephron and nowhere
Ans: The wall of the capillaries is porous. So material from the blood in the glomerulus can easily pass through these pores. On the other hand, all other capillaries on the nephron are without such pores so filtration cannot take place in them. To Download 2nd year Biology all chapter solved exercises from the below link.
