The third choice is the answer.
This is because chemical change occurs when the (for a lack of better wording) interior of the object is changed in the second one the bread is being broken down chemically by the stomach acid this is because the acid is breaking down the formation of the bread dissolving it and chainring it into something else.
In the 4th one the change that is seen is chemical because the formation of the roof is change the physical appearance may be the same (ie. The size & shape) but their are other changes in the color, texture and maybe taste ( don’t taste a rusting roof lol) these are ways in which you can figure out if a change is chemical or physical.
Physical change occurs when the size and/or shape of an object is changed.
Chemical change occurs when the texture, taste and/or color of the object is changed, but-sometimes chemical change cannot be seen.
Hope this helped :)
The red blood cells are cohesive, meaning they want to stick together. if one cell moves along the capillary this cohesion will drag the neighboring cell with it. the cells are also adhesive to the capillary walls, so they stick along the tube lining as they are dragged through the capillary.

Answer:
Beta cells (β cells) are a type of cell found in pancreatic islets, synthesising and secreting insulin and amylin. Beta-cell mass and function diminish in patients with type I or type II diabetes, resulting in inadequate insulin secretion and hyperglycemia.
If hexokinase was expressed rather than glucokinase, the release of insulin from pancreatic β cells would be constant, and changes in serum glucose would not affect the expression of insuline.
