What caused hurricane katrina
elena-14-01-66 [18.8K]
 tropical depression, according to the NOAA. A well-defined band of storm clouds began to wrap around the north side of the storm's circulation center in the early morning hours of Aug. 24. With winds of about 40 mph (65 kph), the storm was named Tropical Storm Katrina. <span>By the time it made its way to southern Florida on Aug. 25, Katrina was a moderate Category 1 hurricane. While it caused some flooding and casualties — two people were killed — during its first landfall, it appeared to be just another hurricane in an active hurricane season. Katrina weakened after passing over Florida and was reclassified as a tropical storm.</span>

The chemical bond between hydrogen and oxygen atoms in a water molecule forms by a shared pair of electrons between hydrogen and oxygen

<h3>Further explanation</h3>

Chemical bonds that occur between 2 atoms can consist of:

  • 1. ionic bonding

The bonding that occurs due to electron handover. It can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases

  • 2. covalent bonding

The bonding that occurs due to the shared use of electron pairs

The two bound atoms contribute their electrons to produce bonds

Generally occurs in non-metallic elements

In the water molecule itself:

Electron configuration H = 1s²

Electron configuration O = 1s² 2s² 2p⁴

H atoms need 1 electron to be stable like the duplet configuration of the noble gas element He and O atoms need 2 electrons to be stable like Ne

So that the O and H atoms contribute their electrons and covalent bonds are formed

The occurrence of polar covalent bonds of water molecules is the electronegative difference between two bonding atoms.

The attraction of electrons (electronegativity) from O atoms in water molecules causes electrons to be attracted more to O atoms and electrons are not evenly distributed so that negative charge/poles appear on O atoms and positive charge/poles are at 2 Hydrogen atoms

Lubov Fominskaja [6]

Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.

<h3>What are skeletal traits?</h3>
  • The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
  • Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
  • Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
  • We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).
