The anterior portions of the nasal cavities just inside the nostrils are known as the Vestibules
<h3>
What are nasal vestibules? </h3>
- The nasal vestibule is the area just inside the nostril (nose opening) that leads into the nasal cavity.
- The nasal vestibule contains cartilage of the nose and is lined with tissue that contains small, course hair. These hairs help filter dust, sand, and other particles to stay them from entering the lungs.
- The vestibule of the traditional adult nose is a specialized organ with very characteristic structures and specific functions and is the beginning of each nasal passage. Here the tract makes its first contact with the outside world of air.
- The vestibule is surrounded almost entirely by its half the nasal lobule, bounded laterally by the ala, or wing, medially by the mobile septum and columella, superiorly by the cul-de-sac and limen vestibuli, and posteriorly by the skin lying on the alveolar ridge of the superior maxilla

The correct options are as follows:
1.GRAVITY.
Mass movement refers to the movement of surface materials such as soils, mud, rocks, etc down a slope. The force of gravity is responsible for pulling the materials down the slope. Mass movement usually occur along mountain side and hill side as a result of angle of repose of the land form involved.
2. MASS MOVEMENT ALWAYS LEADS TO LANDSLIDE.
This statement is not true, mass movement does not always result into landslides. Mass movement basically leads to bulk movement of earth surface materials from one location to another location. It can happen rapidly or gradually over a long period of time.
3. THE ANGLE OF THEIR SLOPES IS GREATER THAN 40 DEGREE.
The principal cause of mass movement is the slope angle of the land form concerned. If the angle is overly steep, that is, above 40 degrees, the force of gravity will pull the surface materials downward causing a mass movement.
4. SLUMP.
Slump refers to the downward movement of large segments of earth surface, which occur when the base of a land form can no longer support the weight at the top of the land form. The sediments usually break off in one piece and water is usually one of the factors that lead to the break off.
5. MUD FLOW.
Mud flow refers to the type of mass movement that involves rapid, surging flow of materials that has been made liquefy by the addition of water. Mud flow usually contains large amount of clay, which makes it fluid in nature and enhances its ability to travel over long distances. Mud flow is usually made up of different materials which have different sizes.
6. EVAPORATED.
Huge amount of water are usually evaporated from different water bodies on a daily basis as a result of heat from the sun. When the cloud become saturated with the evaporated water, the water is release back to the earth in form of rainfall. Thus, the amount of water evaporated from the earth surface and the amount of rainfall released to the earth are usually of equal amount.
7. VELOCITY.
The velocity of a river refers to the speed with which the water body moves through its channels. Water velocity is usually highest near the surface and lowest near the bottom. The higher the velocity of a water body, the higher will be its ability to transport materials and the reverse is also true.
8. GRADIENT.
<span>Gradient refers to the stream grade, which is measured based on the ratio of drop in elevation per horizontal distance. It is usually measured in meter per kilometer or feet per mile. A high gradient implies a steep slope and rapid flow of water while a low gradient translate to slowly moving water.</span>
DNA/fingerprints are all unique, therefor it is easy to match a fingerprint to a person thus they use this mechanism in criminal investigations because only one person woul have matching DNA to the prints on the scene, and that is the criminal.

E. coli belongs to the genus Escherichia
Taxonomically, <em>Escherichia coli </em>is categorized as belonging to the phylum Proteobacteria, class Gammaproteobacteria, family Enterobacteriaceae, order Enterobacteriales, and genus Escherichia (named after its discoverer, Theodor Escherich).
- Escherichia coli (E. coli) are typically found in warm-blooded organisms' lower intestines. The majority of E. coli strains are not harmful, but some can seriously poison food.
- A Shiga toxin-producing E. coli (STEC) is capable of causing severe foodborne illness.
- Raw or undercooked ground meat products, raw milk, and fecal contamination of vegetables are the most common causes of STEC outbreaks.
- The illness is usually self-limiting, but it can progress to a potentially fatal condition like haemolytic uraemic syndrome (HUS), especially in young children and the elderly.

Answer:
The species will eventually become extinct.
Explanation:
If a species habitat is constantly being reduced and destroyed by a numberous number of things such as human construction, then the species will reduce and eventually go extinct. This is due to the fact that a species habitat is everything to them, it gives them a place to feel comfortable and provides them with food and other neccesities. The species would eventually become extinct is the place they need to leave which is their habitat is constantly being destroyed day by day.
