The cellular macromolecules that are referred by the description above are the LIPIDS. The complement pathway system is a constituent of the natural immunity and this provides us a natural defense against infection. In the complement pathway of the immune system, the macromolecules that make this up are the lipids.
Answer:- d. London dispersion
Explanations:- Carbon dioxide structure is given below:
O=C=O
It has two polar C=O bonds but even then it is non polar molecule as it's linear and the dipole moment of one C=O bond is canceled by it's opposite C=O bond.
being non polar, the only attraction forces present in it are London dispersion forces.
Halogens and Alkali react aggressively.
Acceleration = final velocity - initial velocity/time
