• Read the passage below and choose one correct answer for each question:

          Today the most important population trends are the fast growth in the number of elderly people and the sharp drop in the number of teenagers leaving school. The size of the elderly population is growing because people are living longer and fewer babies have been born.
          In 1911, only 5 percent of the UK population was older than 65. Today, the figure is more than 15 percent. Over the next decade the greatest increase will be in people aged 75 and over. The drop in the number of school-leavers was caused by the fall in the birth rate between 1964 and 1977. This trend is known as the "demographic time bomb" - because demographers knew that, once the birth rate fell, there was no way to stop it having an explosive effect on the economy and on society 16 years later.
          However, the impact may well be short-term. According to some forecasters the UK's birth rate may soon become one of the highest in western Europe.

• Trong một quần thể thực vật, khi khảo sát 1000 cá thể, thì thấy có 280 cây hoa đỏ (kiểu gen AA), 640 cây hoa hồng (kiểu gen Aa), còn lại là cây hoa trắng (kiểu gen aa). Tần số tương đối của alen A và alen a là:

• Hỗn hợp M gồm 3 este đơn chức X, Y và Z và số mol của Y bé hơn số mol của X) tạo thành từ cùng một axit cacboxylic (phân tử chỉ có nhóm –COOH) và ba ancol no (số nguyên tử C trong phân tử mỗi ancol nhỏ hơn 4). Thủy phân hoàn toàn 34,8 gam M bằng 490ml dung dịch NaOH 1M (dư 40% so với lượng phản ứng). Cô cạn hỗn hợp sau phản ứng thu được 38,5 gam chất rắn khan. Mặt khác, nếu đốt cháy 34,8 gam M trên thì thu được CO2 và 23,4 gam H2O. Thành phần phần trăm theo khối lượng Y trong M là :           

• Một quần thể gồm 160 cá thể có kiểu gen AA, 480 cá thể có kiểu gen Aa, 360 cá thể có kiểu gen aa, Tần số alen A là:

• , Y, Z là 3 este đều đơn chức, mạch hở không cho phản ứng tráng gương (trong đó X no, Y và Z có 1 liên kết đôi C = C trong phân tử). Đốt cháy 23,58 gam hỗn hợp E chứa X, Y, Z với O2 vừa đủ, sản phẩm cháy dẫn qua dung dịch Ba(OH)2 dư thấy khối lượng dung dịch giảm 137,79 gam so với trước phản ứng. Mặt khác, đun nóng 23,58 gam E với 200 ml dung dịch NaOH 1,5M (vừa đủ) thu được hỗn hợp F chỉ chứa 2 muối và hỗn hợp 2 ancol kế tiếp thuộc cùng một dãy đồng đẳng. Thêm NaOH rắn, CaO rắn dư vào F rồi nung thu được hỗn hợp khí G. Biết các phản ứng xảy ra hoàn toàn. Vậy phần trăm khối lượng của khí có phân tử khối nhỏ trong G gần nhất với giá trị:           

• Một quần thể ngẫu phối đã đạt trạng thái cân bằng di truyền có số cá thể lông đen chiếm tỉ lệ 84%. Biết màu sắc lông do một gen có hai alen nằm trên NST thường quy định; alen A quy định lông đen trội hoàn toàn so với alen a quy định lông hung. Cấu trúc di truyền của quần thể trên là  

• X, Y, Z là ba este đều no và mạch hở (không chứa nhóm chức khác và MX < MY < MZ ). Đun nóng hỗn hợp E chứa X, Y, Z với dung dịch NaOH vừa đủ thu được một ancol T và hỗn hợp F chứa hai muối A và B có tỉ lệ mol tương ứng là 5 : 3 (MA < MB). Dẫn toàn bộ T qua bình đựng Na dư thấy khối lượng bình tăng 12 gam đồng thời thu được 4,48 lít khí H2 (đo ở đktc). Đốt cháy toàn bộ F thu được Na2CO3, CO2 và 6,3 gam H2O. Số nguyên tử hiđro có trong Y là:         

• Một quần thể động vật, xét 2 cặp gen (A, a và B,b) nằm trên một cặp NST thường. Cho biết không phát sinh đột biến mới. Theo lí thuyết, quá trình ngẫu phối có thể tạo ra trong quần thể này tối đa bao nhiêu loại kiểu gen thuộc về 2 gen đang xét?

• Trong các quần thể sau đây, quần thể nào có tần số alen a thấp nhất?

• Chất hữu cơ mạch hở X có công thức phân tử trùng với công thức đơn giản nhất. Đốt cháy hoàn toàn m gam X cần vừa đủ 6,72 lít O2 (đo ở đktc), thu được 0,55 mol hỗn hợp gồm CO2 và H2O. Hấp thụ hết sản phẩm cháy vào 200 ml dung dịch Ba(OH)2 1M, sau phản ứng khối lượng phần dung dịch giảm bớt 2 gam. Cho m gam X tác dụng vừa đủ với 0,1 mol NaOH, thu được 0,9 gam H2O và một chất hữu cơ Y. Phát biểu nào sau đây sai?
