For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.
Explanation:
The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.
The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.
Some elements of the contour lines or that go with them to give better representation are:
- black dots (representing a top)
- thicker lines (every fifth, so that the counting is faster and easier)
- small lines with given direction (representing cliffs or highly steep slopes)
- numbers (providing information about elevation)

I am going to assume it mean what i think it does and say <span>A) Predation</span>
Hydrosphere i believe is the answer
Somebody needs at least one XC to not be colorblind. XcY doesn't have XC, so they are colorblind. XcXC has XC, so they are not colorblind. (a colorblind female would need both to be colorblind - XcXc)
And XcXC female can pass colorblindless onto her children. For example, even if the father was a normal male (XCY), the one possible child could be XcY (with Xc from the mother and Y from the father), which doesn't have XC so its colorblind.
