Answer:
b)
Explanation:
It shows the natrual proggresion of a story and helps blend the narrtive together.
Those molecules that we can glean information about their position via concentration gradient are called morphogens.
<h3>What is concentration gradient?</h3>
The term concentration gradient refers to the difference in the amount of substance on two different sides. This gradient could be used to glean useful information about the molecule position.
Chemical molecules that impart positional information through their concentration gradient are called morphogens.

Based on the chemical equation, to balance the given equation we should use 2 as a coefficients of HCl on reacatnt side of the reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on reactant side as well as on the product side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
In the above reaction equation is not balanced as number of chlorine and hydrogen atoms are not equal on both sides, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.

Answer : The volume of required is, 60 L
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical reaction will be:
From the balanced chemical reaction we conclude that,
As, 1 mole of completely react with 2 moles of
So, 0.3 mole of completely react with moles of
Now we have to calculate the volume of required.
Therefore, the volume of required is, 60 L
