Circumstance <span>that cause an increase in Blood Pressure:
</span>
- increasing levels of aldosterone ((influences the reabsorption of sodium and excretion of potassium in the
kidneys. This will indirectly influence the blood pressure since the
volume of blood will change)
<span>- vasoconstriction ( blood vessels increase their contraction, which equals to more pressure)
</span>
-increased release of renin (Converts angiotensinogen, secreted in the liver, into angiotensin I).
- increased activity of Angiotensin-converting enzyme ( this enzyme converts angiotensin I into angiotensin II increasing vasoconstriction).
Circumstances that cause<span> a Decrease in Blood Pressure:
</span>
<span>- decreased sodium reabsorption ( by decreasing sodium, the amount of water will also decrease or , in other words,will be excreted. Less water, will decrease volume of blood and that means less blood pressure)
</span>
- vasodilation (The smooth muscle in the <span>blood vessels decrease their contraction, which equals to less pressure)
</span>
- declining levels of ADH(ADH <span>is produced in the hypothalamus and stimulates
vasoconstriction plus it promotes water reabsorption in the kidneys. To reduce blood pressure, is important to have ADH levels reduced)</span>

Hello there!
The answer is A, sediments. Mud, silt and clay can all be found at the bottom of a river, where sediment is formed.
Hope this helps!
Answer:
Besides malnutrition, starvation, and epidemic diseases, farming helped bring another curse upon humanity: deep class divisions. Hunter-gatherers have little or no stored food, and no concentrated food sources, like an orchard or a herd of cows: they live off the wild plants and animals they obtain each day
