The correct answer is: When a sperm cell penetrates the oocyte membrane
The oocyte (is arrested at an early stage of the first meiotic division as a primary oocyte. During each menstrual cycle, one the day before ovulation gonadotropin hormone (luteinizing hormone) stimulates completion of meiosis 1. After the meiosis 1, 2 haploid daughter cells are formed: one becomes the secondary oocyte the other forms the first polar body. Newly formed secondary oocyte starts meiosis 2 which arrests at metaphase which will continue after the fertilization.
Explanation:
when trees are cut down, the bare surfaces left behind absorb more heat than the forest they replaced.And that heat helps draw air upward, pulling moist air in from nearby forested land that increases rainfall in the immediate area.
The dehydration is a very common problem seen in elderly individuals. At an elderly age, all the body functions are diminished, which lead to reduction in thirst and body's ability to obtain water. That is why, the elderly people are very susceptible to dehydration.
