Ared blood cell will shrink in size when placed in a more concentrated salt solution because of the passive process called

Osmosis

Explanation:

In a highly concentrated salt solution, concentration of water is comparatively lower than the fluid inside red blood cells. This develops a concentration gradient.

Due to this difference in concentration, the water starts flowing out of the red blood cells across its permeable layer. Due to this movement of water, red blood cell shrinks. This physical phenomenon in which a substance move from a region of high concentration to a region with lower concentration across any permeable membrane is called Osmosis.  

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
