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.

Jobisdone [24]

Answer:

Seizure is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Explanation:

Seizure is also formally known as an epileptic seizure which it's symptoms involve uncontrolled body movements mostly with every part of the body and loss of consciousness. Epileptic seizure lasts for the maximum of two minutes before the person returns to a normal state. Bladder control however, is usually absent at this stage. Epileptic seizure can be caused by either provocation or without provocation

In provocation, the causes are very low blood sugar and blood sodium, severe fever, brain infection or concussion. Without provocation; brain injury or tumor and a stroke.

When a seizure lasts more than a maximum of two minutes, it is declared an emergency but some seizures do last for about five minutes and it is regarded as normal. There hasn't been any form of cure for epileptic seizures but there are temporary treatments which can prevent frequent seizures.
