If a patient is quite ill or may be ill, a line (tube) will be placed in their heart via the blood vessels of their arm so that antibiotics can be pumped directly into the heart, sometimes for many weeks.
Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
An ocean current is any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth's oceans. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.
<span>True. Sphagnum is a genus of mosses that can retain large amounts of water within their cells, due to the presence of pores in cells that can rapidly absorb water through their pores. The acidic water and the lack of oxygen cause the Sphagnum to decompose slowly, producing the accumulation of dead tissue, which can form a mantle from 1 to 9 m deep.</span>
