Cell membrane is a semipermable, which means that certain molecules will be able to pass through the membrane. It is contains phospholipids. But for smaller molecules such as CO2 and Water, it can pass through the membrane through simple diffusion. Cell membrane controls the movement of the materials into and out of the cell.
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)

The amino acid sequence of a protein which is referred to as its primary structure determines the structure or folding pattern of that protein
<u>The illegal wildlife trade </u>or <u>wildlife trafficking</u> is the commercial process that involves the trade of non-domestic species (animals or plants), or in some cases certain parts of individuals. These species are rare and endangered and thus this practice is harmful and represents an increasing dangers of extinction.
This practice is highly illegal, but unfortunately, at the same time, due to the rarity of the species highly profitable. Efforts are made globally to stop this practice and to avoid the extinction of many endangered species.
Answer:
Notice the large difference in the number of hydrogen ions on the two sides of the membrane. This difference is a hydrogen ion, or proton, concentration gradient. The energy associated with this gradient is used to synthesize ATP from ADP and Pi. This occurs at the ATP synthase complex.
Explanation:
