Answer:
This demonstrate the transforming principle.
Explanation:
Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.
When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.
Answer:
Every organisms on the planet requires a specific environmental conditions for its growth and survival. If the environmental condition is favorable, the organisms grow fast and if the conditions are not suitable so it adversely affected the organisms. For example, plants grow best at the temperature between 25 to 40 Celsius. If the temperature goes below 25 or above 40, the growth decrease and sometimes the plant dies. So climate and abiotic factors such as temperature, humidity, light intensity etc has a great impact on the organisms.

Answer: Option D.
Gastroesophageal reflux disease.
Explanation:
When a person stomach is removed by an operation called gastrectomy . The surgeon connects the oesophagus, a tube that runs from the throat to the stomach to the small intestine. When this happen , there will be acid reflux i.e acid flows back into the oesophagus and causes irritation of the food pipe or oesophagus, this is called Gastroesophageal reflux disease. This occur because there is no stomach where food will undergo some digestive process but in this case the food flows to the small intestine directly and can result in acid reflux
The symptoms of these are heartburn, chest pain, difficult in swallowing food, lump sensation in the throat e.t.c
