Based on the topographic map of mt. st. helens, what is the contour interval of the volcano about height is 2,950 m?

The correct answer is - 500.

The contour lines on the presented picture are at an elevation distance of 500 meters. The way that we can conclude that is that the top of the mountains is not marked with a contour line itself, as in pretty much all cases it is above the last contour line, and bellow the contour line that would come next in order, so in between height.

In this topographic map we have 5 contour lines, so 5 x 500 is 2,500 m of elevation. The next contour line would come on 3,000 m, but Mt. St. Helens doesn't have that elevation as it is lacking 50 m, so the last contour line is the one on 2,500 m, while the top of the mountain will be marked with a special sign.

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

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.
