Capillary action<span> (sometimes </span>capillarity<span>, </span>capillary motion<span>, or </span>wicking<span>) is the ability of a </span>liquid<span> to flow in narrow spaces without the assistance of, or even in opposition to, external forces like </span>gravity<span>. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied </span>carbon fiber<span>, or in a cell. It occurs because of </span>intermolecular forces<span> between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of </span>surface tension<span> (which is caused by </span>cohesion<span> within the liquid) and </span>adhesive forces<span> between the liquid and container wall act to propel the liquid.</span><span>[1]</span>
The correct answer is isobar.
The isobars refer to the lines of constant pressure. It is a line drawn on a map of a weather linking the points of equivalent pressure. The isobars are produced from mean sea level pressure reports and the values of pressure are illustrated in millibars.
The isobars help in demonstrating that how pressure are changing over space and so assist in illustrating the large-scale weather patterns across a region on the map.
Most galaxies have billions of stars.
Answer:
Explanation:
Gene expression can be define as a process that occur in every living cell of the organism. It is a process in which information carried by the gene is used for the synthesis of a functional gene product. These products are proteins, but from the non-coding regions of the gene products like transfer RNA (t-RNA) or small nuclear RNA (sn-RNA) can also be produced.
