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.
The 2% of the insects will begin to reproduce and grow their population exponentially and in time enable the population to recover. This is if the population is large enough to enable random mating. The 98% reduction in population drastically reduces competition for the remaining individuals hence giving them abundant resources for them to thrive.
Answer:
Explained below:
Explanation:
Type of homeostatic mechanism in the human body which is most common is the maintenance of body fluids, dilute and solutions of water that carry liquefied chemicals found in internal part of the cell and the surroundings of them. the internal part of the cells, it is named as intracellular fluid, the external part of the cells, it is named as extracellular fluid. All the materials such as oxygen, nutrients, proteins, and ions, are needed for survival.
To calculate the population density, you will divide the population by the size of the area. Hope I helped!
