Well...bear with me, because I may use some off-hand phrases and different words. And in the interest of education, don't laugh when you hear some...familiar words.\n\nThere is a process in which it is done. The mature egg in the woman's vagina is met with the mature sperm in the man's testicles through intercourse. This is called fertilization. As soon as the egg is fertile, it becomes known as a zygote. The zygote is then transported to the womb, an organ in the female reproduction system that can expand to the size of a basketball, if the circumstances permit it to. The egg sticks to the side of the womb and grows, multiplying in cell count, fron 1 to 2, to 4, to 8, and et cetra, for the first four months, also called the first Trimester. then it is called an Embyro. for the next trimester, the embyro will assume human characteristics, like arms and legs, and the heart will start beating. For the final trimester, the baby will gain muscle mass and fatty tissue, the tissue that will protect the new baby from harmful impact and harsh weather. After the final trimester, the baby can be given birth via vaginal birth, where the baby comes through the vagina of the mother (a process that is, indeed, very painful), or Cisarean section, also known as C-section, where the mother is surgically cut open to remove the baby (don't worry, the doctors put her back together). The baby is then taken to a maternity ward for 3 days, so it can get used to the air and oxygen (12 months in water does make for a environmental shock!). Then the mother is able to take home the baby, her new son or daughter.

The fallopian tube?\n\nHow many more homework questions do you have?
57763
are you not in high school yet? Well, two people have sex, sperm tries to make it to an egg in the female body once it does it latches on germinates and then a fetus is made. fetus grows into baby inside amniotic sac, once baby is born comes out of cervix and umbilical cord is cut and theres ur baby.

Double fertilization isn't seen in gymnosperms in the true sense of the word. This is because the endosperm in gymnosperms is a prefertilization product which is haploid. In angiosperms, the sperm nuclei are involved in the formation of both Primary Endosperm Nucleus or PEN from the central cell as well as fertilization of ovum or egg. Therefore it is called double fertilization.

At thirteen, usually!\nIt is a flush of an un fertilized egg produced by female.\nOf course, only female produce eggs.\nIn human if it is fertilized then it will become baby.

External Fertilization, called spawning.  Thouh it really depends on the type of fish.  Some, like some species of sharks, have internal fertilization and the males of adapted fins that work for the insertion of the sperm, called claspers in the case of sharks.  \n\nBut in general, most fish have external fertilization.  One of the fish, either male or female, set of the nesting site.  Usually behind a small ledge of rocks so the water is turentual, which aerates the water supplying oxygen to future eggs.  The female lays the eggs there, and either right after or at the same time, the male release the sperm upstream to the brood of eggs.  This washes the unfertalized eggs with the sperm, and hopefully fertilizing most of them.\n\nhope i helped!!!

when the egg and sperm unites theres fertilization. after that unity, the egg and sperm will become multiples cells which would eventually become a fetus and growing and growing to become a baby. that baby will then come out either from your mother's abdomen (c-section) or vagina (normal delivery)

In short Meiosis and Fertilisation.\n\nFertilisation brings each haploid gamete cell together, that is, a sperm and an egg. Each of these gametes carries a single copy of each chromosome. It is not until fertilisation that the chromosomes from each parent come together to form the diploid embryo.\n\nBut it's important to note that although we are walking around with 2 copies of our chromosomes, our gametes only have one. This is because the gametes are formed through the process of Meiosis, which halves our DNA. This allows the offspring to have a copy of each chromosome from each parent.

Catholics and many other Christians believe that a soul is placed in a human at the point of conception. This is why the Church celebrates on March 25 the feast of the Annunciation when Mary said "Yes!" to God and Jesus was conceived. Life is sacred and a gift from God. \n\nIn most in vitro fertilizations, more than one egg is fertilized. Several embryos are then placed into the mother's womb. The remaining embryos are either destroyed or frozen. Destroying human embryos is abortion and freezing them with an unknown future hope of ever being born is not respecting the dignity of human life.\n\nLater if and when the embryos begin to grow in the mother, all but one or two are usually aborted, again killing sacred human life.\n\nWith love in Christ.

Cephalization is the evolutionary process by which sensory organs move to the head region. Cephalization is intrinsically connected with a change in symmetry. It accompanied the move to bilateral symmetry made in flatworms, with ocelli and auricles placed in the head region. The cephalization / bilateral symmetry combination allowed animals to have sensory organs facing the direction of movement, allowing a more focused assessment of the environment into which they are moving. In addition to a concentration of sense organs, all animals from annelids on also place the mouth in the head region. This process is also tied to the development of an anterior brain in the chordates from the notochord. A notable exception to the trend of cephalization throughout evolutionary advancement is phylum Echinodermata, which, although having a bilateral ancestor (as evidenced by their embryology), develop into a pentaradial animal with no concentrated neural ganglia or sensory head region. However, some echinoderms have developed bilateral symmetry secondarily.\n\nIn neuroembryology, neural induction of the ectoderm forms a neural tube which undergoes cephalization to form initially 3, then 5 vesicles as a developing embryo. It is the internalized ectoderm which goes on to become the central nervous system, peripheral nervous system and epidermis.

1.what is the first obstacle for sperm in the vagina? The first obstacle would probably be the acidity of the vagina.\n\n2.How do sperm know whaer to go? They don't really.  Thats why it is o hard to get pregnant.  They get stuck and lost on the way.  But the female orgasm does help this process.\n\n3.what happens to the uterus when it fertilise egg?  When a fertilized egg moves into the uterus it will attach to the wall.  The lining is not shed (no period) and the baby uses this as nutrients until its placenta has formed.\n\n4.At what ege does the baby have all the organs it needs?  Week 8.\n\n5.what causes morning sickness??  A surge in hormones.  Same thing happens when you start anti depressants.\n\n6.what do babies hear in the uterus?  Muffled noises.  Voices, music, mom breathing, heart, intestines, dogs, etc.  Same things you can hear when you are underwater.

nice philosophical question - the answer is the same as: \nwhich came first:  human being OR spermatozoide??\n\nso it's all a question of talking for hours like policians and never answering the real problematic!

You should have learned this in high school.  Only men produce sperm.  Women produce the egg, which gets fertilized by the sperm.
