It implants itself to the walls of the uterus (endometrium) by umbilical cord.
Answer:
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.
Explanation:
In the Cape bee, female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilized by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally
Answer:
So blood can reach the fetus
Explanation:
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:
Wavelength and frequency are inversely proportional to each other. Such that longer waves have lower frequencies, and shorter waves have higher frequencies. The amplitude or height of a wave is measured from the peak to the trough.
