Hi you’ve only provided one of the options but I don’t know if this will help. The cell membrane is a Thin flexible barristers that surround all cells. Selectively permeable is some substance to pass across while others cannot. Hopefully that can give you give an idea.
Answer:
While digesting food, the liquid food then enters the small intestine where the acid is _neutralized_, and enzymes break down fat, protein and carbohydrates for absorption by tiny hairs called villi.
Explanation:
The small intestine is where most chemical digestion occurs. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine through the pancreatic duct.
The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes <em>bicarbonate to be released into the small intestine from the pancreas in order to </em><em>neutralize</em><em> the potentially harmful acid that comes from the stomach.</em>
This is to protect the cells lining the small intestine from the acid.
Answer:
585ml
Explanation:
13 fold means that volume of the diluted solution is 13 times higher than the volume of the stock.
It means you have to perform 1:13 dilution
D f = Vdiluted/ Vstock
Vdiluted = 13 × Vstock
Vdiluted = 13 × 45ml
Vdiluted = 585ml
You will need to add enough water to the stock (MgSO4) solution till it gets to a total volume of 585ml
