The answer is false.
The group of similar cells working together to perform a specific job is called a tissue. The functional group of multiple tissues is called organ. Functionally related organs form organ systems, which all together form one organism.
So, surgeon is working at the organ level. The lungs are the organs of transpiration. Since they are organs, they consist of multiple tissues, which consist of many cells. But the surgeon does not work on one single cell, he works with the whole organ.
Answer:
Mutualism is a close interaction within ecology, from which both organisms have a certain advantage. Mutualism is usually not necessary for the organisms, and the relationship is often short-lived. An example is the cohacks (birds), which occasionally use larger ruminants as a pantry. Both parties benefit from the birds eating parasites in the ruminant's skin, but they are not dependent on it.

Actually Welcome to the Concept of the energy conversion
=> ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell.
=> When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
Answer:
As the food moves through the gastrointestinal tract, and when it reaches the duodenum via the stomach, the food or the paste, that is, chyme becomes acidic because of the presence of acid in the stomach. When this acidic chyme moves towards the first section of the duodenum, it results in the discharging of cholecystokinin and secretin from the duodenal mucosa, which further instigates the pancreas to discharge alkaline pancreatic juice that comprises pancreatic enzymes and bicarbonate ions.
Now the bicarbonate ions will turn the chyme alkaline and is now known as chyle. It is made alkaline as the pancreatic enzyme needs alkaline pH to function on food. The intestinal juice is also secreted due to the discharging of similar hormones as mentioned above. However, the difference is that both the mechanical stimulus and nervous stimulus results in the discharging of intestinal juice, though it is not true for pancreatic juice.
