Answer:
Option D, 4,2,1, 3
Explanation:
The mitochondrial respiratory chain (MRC) comprises of four membrane bound complexes and it involves the following steps
a) RC complexes (RCC) I and II reduces the RC’s equivalent where RCCI i.e receives electron from the NADH.
b) These electrons are then transferred to the flavin mononucleotide factor and then passed on to the Fe-S embedded cluster .
c) These electron reduces the coenzyme Q to ubiquinol
d) With in the inner mitochondrial membrane (IMM), protons are trans located from IMM to the intermembrane space (IMS)
e) RC complex II then transfer electron from succinate to the cofactor FAD
f) From FAD proton are transferred to the FeS cluster and on the other hand electron move from QH2 to the RC complex III
g) This RC complex III give its electrons to the cytochrome and they are further passes on to the RC complex IV
h) With four redox centers, the terminal RC complex translocate protein by using energy produced in electron transfer thereby converting oxygen into water.
Hence, the correct option is D
Answer:Radiometric dating allows us to indirectly date fossils up to billions of years old based on minerals in surrounding volcanic strata. The correct option is D.
Explanation:
Radiometric dating was first used by geologist after being published by Bertram Bollywood in 1907. During volcanic eruption, some minerals ( carbon) are trapped within the volcanic strata. These minerals are made up of radioactive isotopes which are unstable as they form decay products with a known constant rate of decay. This enables them to :
- access information about the absolute age of rocks,
- date a wide range of natural and man-made materials
- know even the age of earth. I hope this helps. Thanks

Multicellular organisms are referred to as eukaryotes while the opposite, unicellular organisms, are called prokaryotes. Among all the kingdoms, I believe the kingdom which all organisms are multicellular are Animalia and Plantae.
Answer: Both smallpox and COV 19 are novel diseases in their respective timelines. Both spread by inhaling infected droplets, albeit COV 19 is transmitted through aerosols and surfaces touched by infected people as well.
