What's New In meiosis the cell goes through similar stages in mitosis and uses similar strategies to organize and separate chromosomes. However, the cell has a more complex task in meiosis. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but non-identical chromosome pairs an organism receives from its two parents. These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis III. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Stages of Meiosis I In meiosis I, homologous chromosomes are separated into two cells such that there is one chromosome (consisting of

When I waa just a little girl, I realized that my grandmother was a witch. ( 1)that time, was reading atories about Snow White and Sleeping Beauty and (ア) (nbout/1/that'a/witchen /learned/ where) My grandma was good to talk to. In many waya ahe waa your typical grandmother ahe atudied tai chi, and made pottery and quilta. But if ahe wants to fool me(2 ) believing ahe ia not a witch, ahe ahould get rid of her black cat. Only she can touch Satan,and that devil eat's green eyes are really Bcary. Anyway, over the yeara I got into the habit of going( 3 )to mee Grandma after school and telling her all my troubles, I never let her know that I knew her secret and ahe didn't sny anything(4)。 But when I was in my second year in high achool, I ran into a problem. It required a little magie to set right, so I thought I'd aak her straight out. “Grandma, are you a witch? 1 said. "Of course," she said. "I thought you knew." "Do you know how to cast apella and make potiona?" "wDepends," ahe said. "What's on your mind? Is ita love potion you need? "Tell me all about it, Amy" “Well," I said, "you know it's my Year 10 Formal in November, and nobody haa aaked me yet. Id really like to go with Stevo. You know him. He's always lived next door to us. But he goes out with all the popular girla at school and thinka ( 5 ) me as just hia siater." My grandma thought a minute then went into her bedroom. She came back and put a little bottle of red liquid in my hand. “This will fix him," she said. “How can I get him to take it?" “Oh, you're the one ( あ ) has to take it. Three sips are all you'll need. When will you see him next?" “He's coming to my house tomorrow after school." “When he comes, ask him in and take a sip of the magic potion. Then take your shoes8 off and go outside, and jump up and down the path for a minute or so on that pogo stick I gave you." “He'll think I'm crazy. I can't do that." “Do you want him to take you to the Formal or not?After that, come inside and take another aip. Then let that lovely hair of yours out of that ponytail, brush it for two minutes, and put a flower in your hair. After that sit on the floor and take the third sip." “Will that work? Hell think I'm crazy." “Just think positive," said my grandma, "And by the way, don't wear that old pair of jeana and that baggy shirt" Next day I was waiting for Stevo after school. I had on my new akirt and my new blouse. Iopened the door, still not sure if I'd be able to go through ( 6 )the plan. “Where are you off to?" he asked. "Anyway I can't atay long." “It'e OK,"I said looking at my watch. "Tve got plenty of time." And before I knew it I'd taken the first sip. It (4) (the medicine/abit/1/ike /used/tasted) to take when I wasa little ldd. “You sick or something?" he said. 1 just gave him my new Mona Lisa smile and kicked off my ahoes. "Juat a sec," I said. I picked n the pogo stick from the corner, went out the front door, and jumped up and down the path for a while. I saw Stevo looking out the window at me with ama puzzled expression. Iwent back inside and he said, "You all right?"
