Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>

If you remove a secondary consumer then, primary consumers have the chance to overpopulated and Tertiary consumers underpopulate or die off because there's no secondary consumers to eat
Answer:
Selective permeability is a property of a cell membrane that allows it to control which molecules can pass (moving into and out of the cell) through the pores of the membrane
Explanation:
The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose, <u>Celluloso </u> and other sugars) cannot. Water can pass through between the lipids.
Answer:
Taft appointed a secretary of the interior who undid some of Roosevelt’s conservation work.
Explanation:
From Roosevelt's guidance, Taft had the little opponent for the Democratic appointment for the administrator in 1908 and easily destroyed William Jennings Bryan for the administration that November. In the White House, he concentrated on East Asia more than European interests and regularly occurred to prop up or eliminate Latin American powers. Taft asked decreases to trade charges, then a major cause of national revenue, but the resulting proposal was massively affected by special matters.
