During mitosis, cells replicate all their contents, including chromosomes, and divide to form two identical daughter cells.
<h3>What is Mitosis?</h3>
Mitosis is the process by which one cell divides into her two identical daughter cells (cell division).
- During mitosis, the cell divides once to form two identical cells.
- The main purpose of mitosis is to grow and replace worn-out cells.
- Mistakes made during mitosis, if not corrected in time, can lead to DNA changes that can potentially lead to genetic diseases.
Mitosis is divided into following phases:
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase

Answer: Atmospheric Nitrogen is unreactive
Explanation:
The atmosphere is made up of about 80% Nitrogen, 16% oxygen, about 4% carbon dioxide, rare gases etc.
However, the 80% Nitrogen is highly unreactive, and needs to be trapped by competent micro organisms known as nitrogen-fixing bacteria in the root nodules of legumes.
Then, it is converted to several forms like nitrites, nitrates (easily absorbed by plants), ammonia and finally escape to the atmosphere again.
This brief illustration explains the NITROGEN CYCLE, and it is the only means by which plants and animals can use the highly unreactive nitrogen
Answer:
Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.
The renal tubule would be the vessel within the nephron loops that functions to collect ions and water back into the blood. In addition, these vessels are the one responsible for emptying the collecting duct and reabsorbs salts present in the bloodstream and disperses it back to the blood.
