    What are the two poles of magnet

    North and South magnetic pole

  • 10

    It attract objects that are made from certain metals, specially iron and nickel.

    Magnet

  • 11

    These materials are slightly attracted by magnets.

    Paramagnetic Materials

  • 12

    These fields allow magnets to attract objects without touching them.

    These materials are strongly attracted by magnets.

    Ferromagnetic Materials

  • 15

    It is the bending of a wave when it passes from one medium to another

    If two magnets were in this order: NS SN they would attract

    False

  • 19

    A ferromagnetic material is a material that shows strong magnetic effects

    True

  • 20

    A magnet made of a material that keeps itd magnetism is known as a temporary magnet

    False

  • 21

    By hitting it very hard, magnet temporarily lose its magnetism

    False

  • 27

    The pushing a pulling force of a bar magnet strongest at the end of a magnet

    True

  • 28

    They are enclosed in the scrotum.

    Testes

  • 29

    Is responsible for many of the male characteristics.

    Testosterone

  • 30

    Collects mature sperm which is eventually propelled through the vas deferens.

    Epididymis

  • 31

    Sperm travel through this tube, joins with urethra.

    Vas deferens

  • 32

    The tube is cut to prevent sperm leaving (and fertilizing an egg) This procedure can be done right in the doctor's office.

    Vasectomy

  • 33

    Gland that produces a fluid that carries sperm during ejaculation. It surrounds the urethra.

    Prostate

  • 34

    This is where the eggs are produced through cell division (MEIOSIS)

    Ovary

  • 35

    Results in four daughter cells being produced that have HALF the number of the original cell.

    Meiosis

  • 36

    Develop when a single zygote splits. The babies are genetically identical. They also share one placenta.

    Identical twins

  • 37

    Develop from the fertilization of two individual eggs.

    Fratenal twins

  • 38

    Is responsible for the appearance of secondary sex characteristics of females.

    Estrogen

  • 39

    Regulates menstruation

    Progesterone

  • 40

    A fertilized egg

    Zygote

  • 41

    An egg is usually a few days old before it implants in the uterus. At this point, it has already divided several times and is called a

    Blastula

  • 42

    Consists of a body and a cervix. The cervix protrudes into the vagina. Maintains an environment for accepting a fertilized egg.

    Uterus

  • 43

    If no fertilized egg reaches the uterus, the lining is shed monthly in a process known as

    Menstruation

  • 44

    The start of the menstrual cycle
