Plants need to have chloroplasts, because chloroplasts are responsible for converting solar energy into chemical energy. By doing this, the plant is able to perform photosynthesis, which then provides the food energy that the plant needs. Without chloroplasts, the plant would die.
Answer: the question is <u>What activities of the body are responsible for the sympathetic nervous system and for which parasympathetic? </u>
is it right thats what the question means?
answer in eng: The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.

Number of Moles are calculate by using following formula,
Moles = Mass / M.mass --- (1)
M.mass is calculated by adding the atomic masses of all elements present in molecule, Since, MgCl₂ contains one Mg (atomic mass = 24.3 g/mol) and two Cl atoms (atomic mass = 35.45 × 2 = 70.9 g/mol), So,
Molar mass = 24.3 g/mol + 70.9 g/mol
Molar Mass of MgCl₂ = 95.2 g/mol
Now, putting values in eq. 1,
Moles = 310 g ÷ 95.2 g/mol
Moles = 3.256 moles
Answer:
False
