The differences between true experiments and quasi-experiments is that in a true experiment, participants are randomly assigned to either the treatment or the control group, whereas they are not assigned randomly in a quasi-experiment.

What part of the female system is the usual site of fertilization of the ovulated oocyte?.
Paul [167]

Fertilization of the egg cell by the sperm usually takes place in the fallopian tube. The fertilized egg then travels to the uterus and implants in the endometrium.

<h3>What are fallopian tubes?</h3>
  • Fallopian tubes are also called oviducts or uterine tubes. It is the passage through which the egg enters the uterine cavity from the ovary.
  • Fallopian tubes are part of the reproductive tract. They have a smooth muscle wall, an inner mucous membrane, and an outer layer of loose supporting tissue (serosa).
<h3>Why does fertilization take place in the fallopian tubes?</h3>

The fallopian tube (oviduct) regulates fertilization through sperm induction and sperm hyperactivity. Sperm induction is achieved by rheotaxis, thermotaxis, and chemotaxis. Rheotaxis is caused by tubal fluid that creates a current flow from the tubal ampulla to the tubal isthmus.

Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.
