I believe the answer is B because the egg becomes fertilized by the sperm inside the body.
The answer would be "the boiling and freezing points of water."
Interphase: Chromosomes duplicate, and the copies remain attached to each other.
Prophase: In the nucleus, chromosomes condense and become visible. Spindle fibers begin to form.
Prometaphase: The nulcear membrane breaks apart, and the spindle starts to interact with the chromosomes.
Metaphase: The copied chromosomes align in the middle of the spindle.
Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.
Telophase: Nuclear membranes form around each of the two sets of chromosomes, they begin to spread out, and the spindle begins to break down.
Cytokinesis: The two cells split into two daughter cells, each with the same number of chromosomes as the parent cell.
Answer:
Explanation:
Ammonia is associated with aquatic animals; urea is associated with most terrestrial and semiterrestrial vertebrates, but rarely land invertebrates (Campbell et al., 1972); and uric acid is the major product of terrestrial invertebrates, birds and reptiles (Prosser & Brown, 1961).
Sulfur has six valence electrons, meaning that each atom of this element has six electrons in its outermost shell.
