Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Living things include both the visible world of animals, plants, and fungi as well as the invisible world of bacteria and viruses. On a basic level, we can say that life is ordered. Organisms have an enormously complex organization. We're all familiar with the intricate systems of the basic unit of life, the cell. Life can also "work." Living creatures can take in energy from the environment. This energy, in the form of food, is transformed to maintain metabolic processes and for survival. Life grows and develops. This means more than just replicating or getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured. Life can reproduce. Think about the last time you accidentally stubbed your toe. Almost instantly, you moved back in pain. Finally, life can adapt and respond to the demands placed on it by the environment. There are three basic types of adaptations that can occur in higher organisms.

Reversible changes occur as a response to changes in the environment. Let's say you live near sea level and you travel to a mountainous area. You may begin to experience difficulty breathing and an increase in heart rate as a result of the change in altitude. These symptoms go away when you go back down to sea level. Body-related changes occur as a result of prolonged changes in the environment. Using there previous example, if you were to stay in the mountainous area for a long time, you would notice that your heart rate would begin to slow down and you would begin to breath normally. These changes are also reversible. Genotypic changes (caused by genetic mutation) take place within the genetic makeup of the organism and are not reversible. An example would be the development of resistance to pesticides by insects and spiders.

Which type of adaption is permanent?

A. Body-related

B. Reversible

C. Genotypic

Đáp án chính xác

D. Environmental

Trả lời:

verified Giải bởi Vietjack

C

Kiểu thích nghi nào là vĩnh viễn?

A. có liên quan tới cơ thể.

B. có thể đảo ngược.

C. kiểu gen.

D. thuộc về môi trường.

Dẫn chứng câu gần cuối bài: “Genotypic changes (caused by genetic change) take place within the genetic make up of the organism and are not reversible”

Tạm dịch: Sự thay đổi kiểu gen (bị gây ra bởi biến đổi di truyền) diễn ra ở trong cấu trúc gen trên cơ thể và không thể đảo ngược.

=> Tức là kiểu thích nghi biến đổi gen này một khi đã xảy ra là không thể thay đổi, không thể biến đổi ngược trở lại được.                 

=> Đáp án C

DỊCH BÀI

Sinh vật bao gồm cả thế giới hữu hình của động và thực vật cũng như là thế giới vô hình của vi khuẩn và vi-rút. Ở mức cơ bản, chúng ta có thể nói rằng sự sống là được sắp xếp. Sinh vật có tổ chức cơ quan rất phức tạp. Sự sống cũng có thể “hoạt động”. Sinh vật có thể lấy năng lượng từ môi trường. Năng lượng này ở dưới dạng thức ăn, được chuyển hoá để duy trì quá trình trao đổi chất và để tồn tại. Sự sống lớn lên và phát triển. Có nghĩa là hơn cả việc kích thước càng ngày càng lớn thêm. Các sinh vật sống còn có khả năng tự phục hồi khi bị thương. Sự sống có thể sinh sản. Sự sống chỉ có thể đến từ các sinh vật sống khác. Sự sống có thể phản ứng. Hãy nghĩ về lần cuối cùng bạn vô tình bị vấp ngón chân. Gần như ngay lập tức, cơn đau ập tới. Cuối cùng, sự sống có thể thích nghi và phản ứng lại được với những yêu cầu mà môi trường đặt lên nó. Có 3 kiểu thích nghi có thể xảy ra ở các sinh vật cấp cao hơn.

Những thay đổi có thể đảo ngược xảy ra như một phản ứng đối với những thay đổi trong môi trường. Giả sử bạn sống gần biển và bạn đi du lịch tới một vùng núi. Bạn có thể bắt đầu cảm thấy khó thở và tăng nhịp tim do thay đổi độ cao. Nhưng những triệu chứng này sẽ biến mất khi bạn trở lại vùng biển.

Những thay đổi liên quan tới cơ thể xảy ra như là kết quả của những thay đổi kéo dài trong môi trường. Sử dụng tới ví dụ trước, nếu bạn sống trên núi 1 thời gian dài, bạn sẽ thấy rằng nhịp tim của mình giảm xuống mức ổn định và bạn sẽ thở được như bình thường. Những thay đổi đó cũng có thể đảo ngược lại. Sự thay đổi kiểu gen (bị gây ra bởi biến đổi di truyền) diễn ra ở trong cấu trúc gen trên cơ thể và không thể đảo ngược. Ví dụ như sự phát triển khả năng kháng hóa chất diệt côn trùng của các loài công trùng và nhện.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

For many American university students, the weeklong spring break holiday means on endless party on a sunny beach in Florida or Mexico. In Panama City Beach in Florida, a city with permanent population of around 36.000, more than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the United States

A weeklong drinking binge is not for everyone, however and a growing number of American university students have found a way to make spring break matter. For them, joining or leading a group of volunteers to travel locally or internationally and work to alleviate problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel good about.

During one spring break students at James Madison University in Virginia participated in 15 alternative spring break" trips to nearby states, three others to more distant parts of the United States and five international trips. One group of JMU students travelled to Bogalusa, Louisiana to help rebuild homes damaged by Hurricane Katrina. Another group traveled to Mississippi to organize creative activities for children living in homeless shelter. One group of students did go to exhausting physical labor such Florida. but not to lie on the sand. They performed as maintaining hiker rails and destroying invasive plant species that threaten the native Florida ecosystem.

Students who participate in alternative spring break projects find them very rewarding. While most university students have to get their degrees before they can start helping people, students volunteers are able to help people now. On the other hand, the accommodations are far from glamorous. Students often sleep on the floor of a school or church, or spend the week camping in tents. But students only pay around $250 for meals and transportation, which is much less than some their peers spend to travel to more traditional spring break hotspots

Alternative spring break trips appear to be growing in popularity at universities across the United States. Students cite a number of reasons for participating. Some appreciate the opportunity to socialize and meet new friends. Others want to exercise their beliefs about peoples obligation to serve humanity and make the world a better place. Whatever their reasons, these students have discovered something that gives them rich rewards along with a break from school work.
