Answer:
All living organisms reproduce sexually
Explanation:
Not all living organism reproduce sexually. Plant and animal are also living organism but not all plants reproduces sexually. We have sexual and asexual reproduction in plant
Plant reproduce sexually through the fusion of male and female gametes followed by fertilization to produce an offspring. Offspring produce through sexual reproduction have both maternal and paternal makeup.
Asexual reproduction includes binary fission, budding, grafting. It is the production of the exact kind of the parent plant, it does not require fertilization and the parents and the progeny are 100% identical.
Vasectomy and Tubal ligation are operations that have an effect on meiosis in individuals who have elected to have these operations in that it causes meiosis to stop.
A vasectomy or Tubal ligation are operations that are often performed as a method of birth control. A vasectomy is the male version of the operation and includes a procedure that negates the gametes or sex cells from reaching the sperm and being ejected from the body, thus preventing fertilization.
Tubal ligation is a similar process performed on women. The goal of this operation is the same as in the vasectomy, to stop the "egg cell" from being released and thus preventing it from being fertilized. Both procedures have been shown to cause meiotic arrest in individuals following the operation, In some cases, meiosis resumes after some time.

Answer:
It represents young or rapidly growing population. In urn-shaped age pyramid, the number of reproductive individuals is higher than the number of pre-reproductive individuals. It represents declining or diminishing population with negative growth.
