The correct answer is :
Some substances but not other can cross the (blank ) membrane of a cell. The blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it
Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary.
Metabolic acidosis is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid production. Or the kidneys excrete too much base.
<h3>What is metabolic acidosis?</h3>
- The primary function of the kidney is to purge toxins from the blood and convert waste products into urine.
- Around 160 grams of weight and one to one and a half litres of urine are excreted daily by each kidney.
- When the kidneys do not properly eliminate acids from the blood into the urine, renal tubular acidosis (RTA) ensues.
- The result is an excessively high blood acid level, or acidosis.
- While having some blood acid is natural, having too much acid can cause numerous biological functions to become unbalanced.
- When there is too much acid in the body's fluids, it is called acidosis.
- When your kidneys and lungs are unable to maintain a healthy pH level in your body, acidosis results.
- Acid is created by numerous bodily activities.

Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control
3.) Corruption
4.) Employment
5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy
8.) Service delivery
9.) Race relations
Answer:
The correct answer is statement b.
Explanation:
This is due to the fact that the reduction of the vast majority of forest land, that is, mainly in Brazil has resulted in the extinction of the unknown and the familiar species. This has also declined the biological diversity and thus has immensely affected the fertility of the soil.
The soil has turned shallow and thus are less fertile in comparison to the Mid-Western United States. The Midwestern parts of the United States possess variety of soils, which are produced due to the glacial deposits and thus provides more fertility to the soil.
