Plzzz help with the one with the membrane picture
3241004551 [841]

Answer:

1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.

2.) The right side represents high concentration because it contains the majority of the solute molecules.

3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.

What do you think would happen if a genetic mutation caused a person's digestive tract to have stratified columnar epithelium in
Eddi Din [679]

Answer:

Absorption and secretion would be impossible within the digestive tract.

Explanation:

Epithelium is one of the tissues found in humans. It is classified as either simple or stratified depending on the number of cell layers. Simple epithelial tissues have one layer of cells while stratified have many layers of cells. Based on the shape, epithelial tissues can either be squamous, columnar or cuboidal.

Due to the single-layer of the simple epithelial tissues, they line the walls of secretory or absorptive organs e.g organs of digestive tract. The stratified epithelium is majorly for protective function due to the number of cell layers it possess and not a good type of epithelium for locations where absorption and secretion of substances is common e.g digestive tract.

Hence, if a genetic mutation causes a person's digestive tract to have stratified columnar epithelium instead of simple columnar epithelium, ABSORPTION AND SECRETION of chemical substances, which is a key feature of organs (stomach, intestine) that make up digestive tracts, will be impossible.
