Answer:
Exterior of the cell
Explanation:
Pancreas is a gland found behind the stomach and it secretes digestive enzymes into the duodenum.
Digestive enzymes are proteins hence leucine will form part of the enzymes.
Digestion of food takes approximately three hours. Therefore, if labelled Leucine is chased down with non radioactive leucine.
Black spots will appear on the exterior of the cells because digestive enzymes are extracellular enzymes .
Answer:
Detrusor & Urethra
Explanation:
The major contractile muscle of the bladder is the detrusor. Urination involves either sustained contractions or short intermittent contractions of the detrusor along with contraction of the muscles in the urethra, the duct from the urinary bladder that conducts urine from the body.
Answer: There are few ‘laws’ in science. Those ‘laws’ are so named for historical reasons, but they are theoretical in nature. They set out what happens when a theory is applied in practice. A theory is simply the best explanation we have for understanding why some process takes place and predicting what the result will be.
Explanation: Anyone who describes something as “just a theory” does not understand what a theory is. Laws are arbitrary human rules. Theories are severely tested and re-tested explanations of why things happen in the real physical world and can be used to make predictions about outcomes.
Some would say that theories are about why something happens and laws (in science) describe what happens. But this simply makes a scientific ‘law’ a subset of a scientific theory, explaining how to make predictions.
