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

stead of simple columnar epithelium?

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.

DENIUS [597]

Explanation:

Understanding through into genetic risk factors for various illnesses in the human population come from mouse research. Manipulation of the mouse genome is quite simple, for example, adding or deleting genes to better understand their function in the body.

The majority of mice and rats used throughout medical studies are inbred, which means they are genetically virtually similar, making the outcomes of medical trials more consistent.

k0ka [10]

Answer:

\huge\boxed{\sf Cerebellum }

Explanation:

Cerebellum is a leaf-like structure that is a part of the hind brain and is responsible for:

  • coordinating skeletal muscle movements.
  • controls movements, posture and balance.
  • involved in learning too.

So, if the cerebellum of the brain is affected/injured, a person can have difficulty in keeping their body in a balanced position, coordinate voluntary movements of skeletal muscles and learning.
