There was a woman who discovered too late that her

Ask: There was a woman who discovered too late that her body was being eaten up by can- cer. She was advised by various physicians to undergo surgery and remove a part of her body where the cancer cells originated. It was believed that the procedure would lengthen her days on earth. She prayed for her situation, asking God to teach her what is best in such circumstance. Her friends advised her to listen to the doctors. But she heard an inner voice. Life is beautiful. Yet the end is certain because even if the surgery will be successful, the day for death will still come around. She, therefore, started to tread on a path that is full of hope and trust. She did all possible ways to delay the spread of cancer-all natural means except for the doctor’s knife to cut through her body, for she had begun to hope for a natural cure, or to face death courageously. Spiritual persons accompanied her in this unique journey; from many parts of the Philippines, communities offered prayers for her. She did not feel bitter; nor did she blame the Lord despite the pain she suffered daily. She continued to believe that God’s wisdom will ultimately decide her fate. Her body succumbed to the evil of cancer after only five months, but her spirit is still undefeated. She returned to the Maker with a smile on her lips and a firm faith that she will be united with God in the afterlife. When she gave up her last breath, her face was radiant and calm. She looked beautiful. Her last days spoke of her brave encounter with life and death. 1.

Ask: Activity 3: Sharing your thoughts

Direction: Make a graphic organizer, to explain When, Where and How life originated on Earth. ​


We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones.

Directions Read through the text about the hypotheses of the origins of life Using
the information from the text
, fill in the table with the hypotheses and their
corresponding descriptions and evidences
The concept of the development of life is an interesting one on several aspects. It
remains one of the key areas for scientific community being actively worked on. We
may never know exactly when and how life originated, but scientists have formulated
several hypotheses that described events that occurred before life could begin. Oparin-
Haldane Hypothesis was independently proposed by J.B.S Haldane and Alexander
Oparin in the 1920s. The hypothesis suggests that life onginates from the formation of
organic molecules from non-organic matter in the presence of extemal energy source
such as UV radiation. In 1953, Harold C. Urey and Stanley Miller tested the Opann-
Haldane hypothesis and successfully produced organic molecules such as amino acids
from some inorganic compounds. Modern abiogenesis hypotheses are based primarily
to Oparin-Haldane’s work and the Miller-Urey experiment. Some evidence of the origin
of life suggests that it may have originated from nonlife in hydrothermal vents on the
ocean floor or deep below the surface of the Earth where protocells could have lived
on methane or hydrogen. Since the 1950s, scientists believed that amino acids can
s called
form protein chains and with the discovery of ribonucleic acid enzymes
ribozymes has confirmed that the first life was self-replicating RNA. This was later
known as the RNA world hypothesis. The Metabolism-First Hypothesis describes the
formation of organic compounds from simple organic molecules which suggests that
metabolism existed first and helped to produce them. Another interesting hypothesis is
the Panspermia which states that life exists throughout the universe and distnbuted by
meteoroids and other near-earth objects. In 1971, this hypothesis was further
established when amino acids such as glycine and other organic compounds were
discovered in Murchison meteorite.
