The Barringer crater in Arizona contains a mineral, stishovite, only known to form under intense pressures caused by a high-speed impact. Which event most likely formed the Barringer crater?

Meteoric impact

Explanation:

An impact crater is usually defined as a circular depression or large scale pit that forms when any meteorite hits the surface of planet or moon or any other astronomical object. This causes immense destruction, wiping out a large number of area. The size of the crater depends upon the size of the meteorite or asteroid. For example, the Barringer crater, which is formed due to the meteoric impact on the earth. This crater is located in Arizona and is primarily comprised of a mineral, known as stishovite, which forms under the condition of extremely high pressure, that is generally caused by a high-speed impact.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
