The correct answer is: A. A watery mixture of partially digested food released by the stomach into the intestines
Chyme or chymus is formed in the stomach, during the process of digestion (it takes 40 minutes to 3 hours to be produced) , and it is transported to the small intestine-duodenum.
In the beginning of the digestion (in the mouth), mixture of food and saliva called bolus, is formed. Mechanical and chemical breakdown of a bolus creates chime which is ready for the extraction of nutrients from it.
Answer:
Live a healthy lifestyle and avoid anything that may trigger such Diseases.
Answer: The correct answer is option D
SECONDARY ACTIVE COUNTER-TRANSPORT
Explanation: Secondary active transport is a type of transport that involves molecules across the cell membrane utilizing or making use of energy in other forms than Adenosine Triphosphate (ATP).
The energy that is being made use of comes from the electrochemical gradient created by pumping ions out of the cell. This can be either via antiport or symport.
Antiport or Counter-transport means that 2 different molecules or ions are being transported at the same time but opposite directions. One of the species is allowed to flow from high concentration to a lower concentration (often Sodium) while the other species is transported simultaneously to the other side.
Example is Na+-H+ counter-transport, the example and advantage of this transporter is clearly seen in the proximal tubules of the kidneys. The mechanism for concentrating H+ is not nearly as powerful as Primary active transport, however it can transport extremely large numbers and thus making it a key in H+ homeostasis in the body.
