Answer:
Follows are the solution to the given question:
Explanation:
Dry Soil weight = solid soil weight = 
solid soil volume =
saturated mass soil = 
The weight of the soil after drainage is =
Water weight for soil saturation = 
Water volume required for soil saturation =
Sample volume of water: 

Soil water retained volume = (draining field weight - dry soil weight)



(Its saturated water volume is equal to the volume of voids)




The pairing that accurately matches a bio molecule polymer with its monomer subunit would be B. Protein and amino acids.
Answer:
b. Beta emission, beta emission
Explanation:
A factor to consider when deciding whether a particular nuclide will undergo this or that type of radioactive decay is to consider its neutron:proton ratio (N/P).
Now let us look at the N/P ratio of each atom;
For B-13, there are 8 neutrons and five protons N/P ratio = 8/5 = 1.6
For Au-188 there are 109 neutrons and 79 protons N/P ratio = 109/79=1.4
For B-13, the N/P ratio lies beyond the belt of stability hence it undergoes beta emission to decrease its N/P ratio.
For Au-188, its N/P ratio also lies above the belt of stability which is 1:1 hence it also undergoes beta emission in order to attain a lower N/P ratio.
The answer is E.
Chemoautotrophs are organisms that use inorganic <span>compounds as an energy source and CO2 as a carbon source. The organisms live in </span>hostile environments like dark depths of the sea. Inorganic energy sources that they use are mostly hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia.
