Answer:
The correct option is;
Sand, clay, and silt
Explanation:
The categorization of soil particles by size can be made into three classes including sand (particle size between 0.05 mm to 2 mm), silt, (particle sizes between 0.002 mm to 0.05 mm) and clay (particle sizes lesser than 0.002 mm), larger particles such as stones, pebbles, boulders and rock other fragments are left out of the textural classification because of their inertness
The combination of the three particle sizes can be found in most soils and their relative proportion defines the texture of a given sample of soil.
Atom refers to a tiny particle, which is the basic building block of all the substances and whose properties determine the characteristics of an element made up of only of those atoms.
All the living and nonliving matter in this world are made up of atoms and elements. Everything in the universe is matter, and matter comprises elements. Some of the elements are important to living things.
Elements are formed by atoms, and atoms comprise protons, electrons, and neutrons. The number of protons in an element's atom signifies the identity of the element.
The cilia propel debris-laden mucus away from lower respiratory system structures.
<h3>
What is function of mucous membrane?</h3>
- Another general defense against possible infections is provided by the mucous membranes that line the digestive, urinary, and respiratory tracts, as well as the nose, mouth, and lungs.
- In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
- Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
- Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.
