the uterine lining thickens to allow an embryo to implant. The reason it thickens is to allow room for blood vessels to supply the area with oxygenated blood. if a child doesn't implant, then it's just superfluous preparation, and the cycle starts again.
The thick uterine lining provides a nourishing environment for a fertilized egg to implant and grow into a developing embryo. It contains nutrients and blood vessels to support early pregnancy and establish a connection with the mother's blood supply. If fertilization occurs and the egg implants successfully, the thick uterine lining helps sustain the pregnancy until birth.

What are two things that make fertilization successful?
For successful fertilization, the sperm needs to reach the egg in the fallopian tube during the fertile window of the menstrual cycle. Additionally, the sperm needs to penetrate the egg's protective layer and fuse with the egg to form a zygote.
What are the fallopian tubes?
The fallopian tubes are thin tubes lined with cilia, connecting the ovaries to the uterus. They provide a pathway for eggs to travel from the ovaries to the uterus, where fertilization typically occurs. If the egg is fertilized, it then implants in the uterus to develop into a fetus.
Why does a sperm cell need large surface area?
A sperm cell needs a large surface area to maximize contact with the egg cell during fertilization. This allows for efficient transfer of genetic material and increases the chances of successful fertilization.
What is pollination and how does it occur?
Pollination is the process of transferring pollen grains from the male reproductive organs (anthers) of a flower to the female reproductive organs (stigma) of the same or another flower. This transfer can occur through various means such as wind, insects, birds, or other animals, which facilitate the fertilization of plants for reproduction.
Why do plants need pollination to occur?
Plants need pollination to reproduce. Pollination is the process of transferring pollen from the male reproductive organs of a flower to the female reproductive organs of the same or another flower. This transfer of pollen is necessary for fertilization to occur and for the plant to produce viable seeds for reproduction.
Why does a female no longer needs thick uterus lining if fertilization doesn't occurs?
The thick lining is prepared by the nature,so that implantation of the zygote should be possible. If there is no fertilization, then this lining is shed away. You have fresh lining for the next month. After all generation next is very much important for the nature.
Is external fertilization sexual or asexual?
Well, there is fertilization in sexual reproduction, but there is not fertilization in asexual because the female reproductive system needs help with the male reproductive system through sex. Without sex, it is asexual. Females need the males sperm in order to fertilize the baby or plant.
What is flower fertililzation?
Flower fertilization is when the pollen gets into the female parts of the flower and the seeds start to form. Each ovule or egg needs some pollen to form a seed.
What classes of vertebrates use external fertilization?
Two classes:Fish and Reptileswhat is interior and exterior fertilization?Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body. External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.Examples of external fertilization are in plants like moss or algae, where the sperm and eggs meet outside of the parent's body and produce a zygote, which then grows into a mature plant. External fertilization in animals are usually in marine organisms, like sponges, because the sperm needs to swim in water to meet the egg.-Your Welcome

Can my girl hamster have a baby without a boy hamster?
No, a female hamster cannot have babies without mating with a male hamster. Hamsters reproduce sexually, so a male is required for fertilization to occur and for the female to become pregnant.
How can impervious be used in a sentence?
A garden fish-pond needs an impervious lining.
Why does a male gamete of a flowing plant have no cell wall?
The male gamete of a flowering plant, also known as a pollen grain, lacks a cell wall to facilitate its movement and fertilization. The absence of a cell wall allows the pollen grain to be carried by air or insects more easily to reach the female reproductive structures for fertilization.
What are the similarities of internal external fertilization?
Both internal and external fertilization involve the joining of sperm and egg to form a zygote. In both processes, the end result is the fertilization of an egg. The main difference lies in where the fertilization occurs - internally within the female's body or externally in the environment.

How do newts reproduce?
Newts reproduce through internal fertilization, where a male transfers sperm to a female through a specialized structure. The female lays eggs, which are externally fertilized by the male's sperm. The eggs hatch into aquatic larvae, which undergo metamorphosis to become terrestrial adult newts.
