TEXT
HOW DID LIFE BEGIN?
Scientists face many mysteries, but there is none so compelling as the mystery of how life on Earth began. The great religions have their own accounts of Creation (it has been done by the God and it took him seven days, according to the Bible, to create the world), but scientists have never able to construct a complete account of the way and moment when dead molecules came together to form organisms that could feed, grow, reproduce and evolve. Nevertheless recent work has suggested some promising theories.
Some new explanations are associated with science fiction. Astronomers Ered Hoyle and N.C. Wickramasinghe suppose that organic molecules fell to the Earth from comets - and indeed meteorites containing organic substances have been found. Biologists Francis Crick and Leslie Qrgel think that Earth might have been seeded with life by some intelligent beings from advanced planets.
The more prevalent theories, however, do not depend on extraterrestrial intervention. They fall into two main categories the view that life began almost as soon as Еarth formed, and the view that life emerged in the result of some chemical reactions in the prehistoric oceans on Earth.
At a symposium chemist Carl Woese of the University of Illinois suggested that life on Earth coincided with the birth of the planet. To his mind, dusty water droplets could have collected the chemicals that rapidly evolved into life. Other chemists think creation took millions of years. Earth began with an atmosphere containing almost no oxygen, but mostly water vapor, methane, carbon dioxide and ammonia. It is simple to make prelife molecules with these gases, suppose Stanley Miller and Harold Urey of the university of Chicago. Chemist Sidney Fox of the University of Miami thinks life began with a protein droplet, perhaps on a volcano.
However the elements of life formed or joined, the more fundamental question goes deeper than chemistry. Theories face a chicken-and-egg dilemma: which came first, an isolated bag of proteins or a naked gene. The question touches the definition of life: is the key feature of life the ability to eat and grow, as proteins do, or to reproduce and evolve, as genes do?
Most scientists, however, believe that the essence of life is evolution, which requires genes. Genes make exact copies of themselves and undergo the mutations and natural selection that produce higher and higher organisms. Among these scientists are Leslie Orgel of the Salk Institute, A.I. Oparin, Russian biochemist. In his book "The Origin of Life" A.I. Oparin wrote:" The origin of life was a transmition from organic to biological chemistry, from lifeless to living matter, from the inanimate to animate realm of nature". According to his theory life arose on earth because of the widespread distribution of carbon, an element with an exceptional tendency to combine with other substances.
All these theories imply that if it happened here, it could happen elsewhere in the universe.

- How can they be saved?
Listen to the extract from a lecture about immunisation. Then listen again and fill in the gaps in the typescript.
Historically, being immunised against diseases is a relatively new thing but that doesn’t mean the idea hadn’t been thought of before. If we go as far back as 429 BC, the historian Thucydides noted that after a (1)…………... plague in Athens, those who survived did not become infected again. This was at a time before there was even recognition of such things as (2)…………………… and viruses.
Nowadays, we take it for granted that we will be vaccinated and avoid diseases like polio but how many of us actually stop to ask ourselves what is behind the (3)………
we have? How does vaccination work? Basically, it is the process by which a person is exposed, that is, made open to an agent so that his or her immune system develops against that agent. The immune system makes antibodies which fight against infection.
Once the human immune system is exposed to a disease, it is able to act against any future infection. Vaccination exposes a person to an immunogen - something which helps develop immunity - in a controlled way by using a (4)……………. dose so he or she doesn’t become ill while being immunised.
The good thing about a vaccination programme is that it can limit the spread of a disease among a population, reducing the risk for people who have not been vaccinated so we have something which is known as herd (5)………………….. . That means when the number of non-immune people has dropped to a certain level, the disease will disappear from the whole population. This is how nowadays we have achieved the elimination of many diseases.

TEXT
THE CELL
A cell is a tiny unit which constitutes the core of all living things: human, animal, plant or microbe. It was an English mathematician and physicist called Robert Hooke who, in 1665, first recorded his observations of cells under a microscope and published them in a book entitled Micrograpliici. Hooke noted that there are single-celled organisms, such as the amoeba, and multi-celled organisms, such as man. In the latter type of organism, it was revealed that the cells are grouped together to form different types of tissues, and the tissues then form organs.
The structure of a cell appears very simple. It is a jelly-like mass, called protoplasm, enclosed by a wall, with a central nucleus. Although research continued into the structure and function of cells, it was not until the late 19th century that a process of staining and fixing tissues was developed. This made it possible for scientists to preserve the cells for more detailed observation under a microscope. It was then discovered that new cells are formed by the division of old ones, and that each cell has its own lifespan. In other words, a cell is born (created), feeds, produces waste, grows, splits to create new cells or disintegrates and dies. Each cell has a specific function and specific characteristics, for example, muscle cells stretch and nerve cells carry information.
Stem cells are central to this infrastructure. These cells provide a remarkable repair system for the body, as they are able to develop into any type of cell. They can continue to redivide as often as possible to replace damaged or dying cells. The cells created from the division of a stem cell can remain stem cells, or become any of the other specific cells (blood cells, brain cells or other) in the organism. The key to the division process lies in the nucleus. The nucleus splits into two identical parts in the shape of rods or threads, which break away in opposite directions and form new nuclei. At this point the cell itself divides and two new cells are born. The rods or threads are called chromosomes. Each chromosome is made up of links of protoplasm called genes joined together in a chain. It is the genes that determine the essence of each cell and its particular characteristics. The number of chromosomes found in a particular organism always remains the same, but it will vary depending on the species; human beings have 48, for example, and sugar cane over 200.
