Answer: In the case of antibiotic resistance, antibiotics cause a selective pressure by killing susceptible bacteria, allowing antibiotic-resistant bacteria to survive and multiply. Selection pressure can be regarded as a force that causes a particular organism to evolve in a certain direction.
Explanation:
Answer:
The correct answer is the duodenum.
Explanation:
Pancreatic juice is an alkaline fluid which contains important enzymes for the digestion of proteins, carbohydrates and fats.
Pancreatic juice is secreted by the pancreas when food enters the stomach which is released into the "duodenum" of the small intestine. The pancreatic juice enters duodenum through a pancreatic duct which joins with the bile duct coming from the liver and form "ampulla of Vater" in the duodenum.
Pancreatic juice helps in digestion of carbohydrates, proteins and fats as it contains pro-enzymes and enzymes like trypsinogen, chymotrypsinogen, lipase and many more. It also makes the acidic stomach solution alkaline due to the presence of HCO₃.
Thus, the duodenum is the correct answer.
The left side of the heart is responsible for receiving blood from the pulmonary circuit from the lungs. So failure of it leads to increased pressure in the lungs (pulmonary circuit). That would cause the right side of the heart, which pumps blood to the lungs) to exert more force to keep blood moving through the pulmonary circuit.
Hope it helps!
