Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Neutron Moisture Meter consists of Amerecium and Beryllium or Radium and Beryllium as the neutron source.
Reason (R) : In case of Amerecium and Beryllium, fast neutrons are produced into the soil, they undergo elastic collisions
with hydrogen nuclei in which neutron loses energy and gets scattered. Since water is the main source of hydrogen in soil
the density of slowed neutron is proportional to the volume fraction of water present in the soil
In light of the above statements, choose the correct answer from the options given below.
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Potassium activity ratio (ARK) is used, in place of K concentration alone, to indicate the intensity factor which
is a measure of K in soil solution that is immediately available for absorption by plant root.
Reason (R) : The absorption of K is influenced by the activity of other cations like Ca?* and Mg?" in the soil solution.
In light of the above statements, choose the correct answer from the options given below.
Read carefully below mentioned statements:
(A) . Organisms with optimum temperature between 20-35 °C are termed as ‘mesophiles’
(B) . Psychrophiles have optimum temperature for growth below 10 °C
(C) . Chemoautotrophs get energy from the oxidation of simple inorganic compounds.
(D) . Heterotrophs derive energy by oxidation of organic compounds
