Dentists say that the most important part of tooth care happens at home. So, what should we do to have good oral teeth?

First of all, we should brush our teeth at least twice a day – after breakfast and dinner. To keep our teeth healthy, we should brush thoroughly for two minutes. Move the brush back and forth and make sure to clean the back, front and top sides of each tooth. Second, among a lot of toothbrushes in the supermarket, we should choose a small-headed soft toothbrush. It can reach all areas of the mouth and doesn't harm our teeth and gums. We should also replace the toothbrush every three months.

Third, we should use mouthwash after brushing. Each tooth has five sides, but a toothbrush cleans only three of them. The mouthwash helps us clean teeth completely. Remember to spit it out.

Fourth, we should choose the best food for the health of our teeth which includes cheeses, chicken or other meat and nuts. These food provide the calcium which helps strengthen the teeth. Some vegetables garlic, ginger or pepper can be used as home remedies for a toothache. Try to advoid snacks, sugary food or soda.

Last but not least, we should visit our dentist at least every six months and every time that we have a problem with our teeth.

Read the text. Choose the best answer A, B, C or D.

Tham khảo cách giải:

Có 2 giống lúa: một giống có gen quy định khả năng kháng bệnh X và một giống có gen quy định khả năng kháng bệnh Y. Bằng cách gây đột biến người ta có thể tạo ra giống mới có 2 gen kháng bệnh X và Y luôn di truyền cùng nhau.

     Cách tiến hành thí nghiệm:

     + Người ta lai hai giống lúa với nhau rồi sau đó xử lí con lai bằng tác nhân gây đột biến nhằm tạo ra các đột biến chuyển đoạn nhiễm sắc thể chứa cả hai gen có lợi.

     + Từ đó chọn lọc cây có kiểu hình mong muốn.

     + Tạo dòng thuần chủng

Bằng cách gây đột biến thì ta hoàn toàn có thể tạo ra giống mới có cả hai gen kháng bệnh X và Y 

- Có tính di truyền cho giống kế tiếp

Cách tiến hành thí nghiệm:

Lai hai giống lúa với nhau rồi sau đó xử lí con lai bằng tác nhân gây đột biến nhằm tạo ra các đột biến chuyển đoạn nhiễm sắc thể chứa cả hai gen có lợi , sau đó chọn lọc cây có kiểu hình mong muốn để tạo dòng thuần chủng.
