False. When using the 40X objective, you should not use the coarse adjustment knob.
Explanation:
The coarse adjustment knob is used with lower power objectives if used at high powers the lens may get broken and also it would be difficult to attain desired focus. The coarse adjustment knob is used to attain the focus of the object by maintaining the distance between the object and the lens. This is the rough focus knob of the microscope and the focus of the object moves very quickly when using coarse adjustment.

Answer:
A) Lipid synthesis : Smooth endoplasmic reticulum.
B) Calcium ion storage : Smooth endoplasmic reticulum.
C) Poison detoxification : Smooth endoplasmic reticulum.
D) Protien synthesis : Rough endoplasmic reticulum.
E) Protien modification and sorting : Golgi apparatus
F) Cisternal maturation : Golgi apparatus.
G) Macromolecule digestion : Lysosomes
H) Autophagy : Lysosome.
Explanation:
<u>Smooth endoplasmic reticulum</u> is involved in the synthesis and storage of lipids . It also stores the calcium ions and contain enzymes responsible for the detoxification of the poisonous substances like CCL4 and other agents. SO the answer of A , B and C is Smooth endoplasmic reticulum.
<u>Rough endoplasmic reticulum</u> contains ribosomes which synthesize protiens thus answer of D is RER.
The <u>Golgi apparatus</u> functions as a factory in which the protiens recieved from the endoplasmic reticulum are modified and sorted and is also involved in cysternal maturation so answer of option E and F is Golgi apparatus.
<u>Lysosomes</u> are the part of endomembrane system involved in the digestion of the macromolecules and in the recycling of the worn-out organelles hence also involved in autophagy. Hence answers of G and H is lysosomes.
