The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.

Answer;
Antibodies.
The human immune system fights infection by releasing antibodies.
Explanation;

These antibodies also activates proteins known as complements which assist in the killing of bacteria, viruses and the infected cells.
The correct statement about hydrochloric acid and acetic acid is : ( A )
The pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.
Given that pH is the inverse of concentration of H₃O⁺ ions , The stronger acid ( Hydrochloric acid ) dissociates in solution producing a maximum amount of H₃O⁺ ion, while the weak acid ( acetic ) will disassociate partially in a solution producing a lesser amount of H₃O⁺ ion.
Therefore the pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.

The rocks which are porous depending on the degree of cementation
include the following:
<h3>What is Porosity?</h3>
Porosity is the measure of empty spaces in a particle which permits the
passage of compounds such as water etc.
The rocks mentioned above have a lot of empty spaces which permits
other substances to pass through them. The remaining rocks are
composed of tightly held grains which reduces their porosity.
