Answer:
The formation and release of substance from a cell or structure is called secretion.
Explanation:
There are many biochemical compounds such as hormones,enzymes which are form in specific organ of the body and is then secreted from its source organ to perform their biological functions.
For example Insulin hormone is produced by beta cells of islets of langerhans of pancreas and then releases to the blood stream to regulate the blood sugar level.
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
It allows them to move smoothly, without getting entangled or broken
The reticulum is responsible :)
It depends on how they are genetically engineered
