the reproduction method work like this
Explanation:
we use that thing and throw it in the recycle bin and it is recycle into a new product so it reduces loss of material it is the use of reproduction
Answer:
In the reproductive process, a male sperm and a female egg provide the information required to produce another human being. Conception occurs when these cells join as the egg is fertilized. Pregnancy begins once the fertilized egg implants in the uterus. The embryo grows and becomes surrounded by structures that provide support and nourishment. Eyes, limbs, and organs appear as the embryo develops into a fetus. The fetus grows inside the uterus until pregnancy ends with labor and birth. By then all body systems are in place—including the reproductive system that can one day help produce another human being.
1. Fertilization: A Sperm and an Egg Form a Zygote
During sexual intercourse, some sperm ejaculated from the male penis swim up through the female vagina and uterus toward an oocyte (egg cell) floating in one of the uterine tubes. The sperm and the egg are gametes. They each contain half the genetic information necessary for reproduction. When a sperm cell penetrates and fertilizes an egg, that genetic information combines. The 23 chromosomes from the sperm pair with 23 chromosomes in the egg, forming a 46-chromosome cell called a zygote. The zygote starts to divide and multiply. As it travels toward the uterus it divides to become a blastocyst, which will burrow into the uterine wall.
2. The Zygote Becomes an Embryo: Development Prior to and During Implantation
Embryonic structures in the womb
A fertilized egg, or zygote, takes about five days to reach the uterus from the uterine tube. As it moves, the zygote divides and develops into a blastocyst, with an inner mass of cells and a protective outer ring. The blastocyst attaches to the wall of the uterus and gradually implants itself into the uterine lining. During implantation, its cells differentiate further. At day 15 after conception, the cells that will form the embryo become an embryonic disc. Other cells begin to form support structures. The yolk sac, on one side of the disc, will become part of the digestive tract. On the other side, the amnion fills with fluid and will surround the embryo as it develops. Other cell groups initiate the placenta and umbilical cord, which will bring in nutrients and eliminate waste.
3. In Eight Weeks, the Embryo Develops; By the End of Week 10 It Becomes a Fetus
Fifteen days after conception marks the beginning of the embryonic period. The embryo contains a flat embryonic disc that now differentiates into three layers: the endoderm, the mesoderm, and the ectoderm. All organs of the human body derive from these three tissues. They begin to curve and fold and to form an oblong body. By week 4, the embryo has a distinct head and tail and a beating heart. Over the next six weeks, limbs, eyes, brain regions, and vertebrae form. Primitive versions of all body systems appear. By the end of week 10, the embryo is a fetus. (Note: Pregnancy is often measured in terms of gestational age—age of the fetus starting with the first day of a woman’s last menstrual period—and embryonic or fetal age—actual age of the growing fetus. We are referring to the gestational age of the fetus.)
