Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.

Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.

These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.

Nguy cơ rụng tóc sớm ở Gen của Đàn ông Ngắn Hói là điều không thể tránh khỏi ở nhiều người già, nhưng nó có thể là mối quan tâm đặc biệt đối với những người đàn ông ngắn. Một nghiên cứu mới cho thấy những con đực có tầm vóc ngắn có nguy cơ bị rụng tóc sớm, ngoài một số bệnh trạng khác. Nghiên cứu phân tích bộ gen của hơn 20.000 đàn ông, khoảng một nửa trong số họ đã hói đầu trước khi họ 50 tuổi. Một nửa số người tham gia không bị rụng tóc và đã được sử dụng để so sánh. Nghiên cứu bao gồm những người đàn ông đến từ Hoa Kỳ, Thụy Sĩ, Hà Lan, Đức, Anh, Hy Lạp và Úc. Các nhà nghiên cứu đã xác định được 63 thay đổi trong hệ gen của con người làm tăng nguy cơ hói đầu sớm. Và trong nhiều trường hợp, các vùng DNA chồng chéo với các gen cho tầm vóc ngắn.

X Read the passage. Answer the questions below.

Scientists have discovered that the ozone layer is getting thinner. Some predict that the sun’s rays will cause a sharp increase in deaths from skin cancer over the next fifty years. These harmful rays can also damage the eyes, create wrinkles, and cause other health problems.

​The stratosphere contains a form of oxygen called ozone. Ozone is a molecule composed of three oxygen atoms. The chemical formula of ozone is 03. Oxygen molecules make up about 21% of all gases in the Earth’s atmosphere. They consist of two atoms of oxygen and are labeled 02. Most ozone found in our atmosphere is formed by an interaction between oxygen molecules and ultraviolet radiation (UV) from the sun. When ultraviolet radiation hits an oxygen molecule, it may cause the molecule to break apart into single atoms of oxygen. These single atoms are very reactive, and a single oxygen atom can combine with a molecule of oxygen to form ozone.

​1.​What do people say about the rate of deaths from skin cancer in the future?​

​2. ​How many oxygen atoms are there in a molecule?​

​3.​What elements participate in the formation process of ozone?​

​4.​What happens when an oxygen molecule and an ultraviolet radiation hit each other?

​​​​5.​What is the feature of single atoms?

Evacuate people out of dangerous areas where safety is not guaranteed; focus on implementing measures to ensure safety for people, especially vulnerable subjects in emergency natural disaster situations. Move boats and means of aquaculture on the sea, along the coast, and on rivers out of the danger zone; organize the tally, guide ships to anchor, or take other measures to ensure safety. Take measures to ensure the safety of houses, offices, hospitals, schools, warehouses, constructions, and economic, security, and defense establishments.

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 from 24 to 33.

Since the world became industrialized, the number of animal species that have either become extinct or have neared extinction has increased. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world's ecosystem. International laws protecting these animals must be enacted to ensure their survival - and the survival of our planet.

Countries around the world have begun to deal with the problem in various ways. Some countries, in an effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission prices to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. This money enables them to invest in equipment and patrols to protect the animals. Another response to the increase in animal extinction is an international boycott of products made from endangered species. This has had some effect, but by itself it will not prevent animals from being hunted and killed.

A. lower

B. raise 

C. make a payment on

D. make an investment toward
