Explanation:
molarity = no. of moles of solute/solution in litres
molarity =0.202/7.98
=0.025 M
The answer is C. <span>The wind removes surface particles, resulting in lower land surface.
Deflation is the process of lifting and moving of tiny particles of soil or sand, brought about by the wind. It can also be associated with soil erosion. This is a common phenomenon in deserts and sand dune areas near the coast.</span>
Answer:
(B) HNO3 + NaOH
Explanation:
Hello,
In this case, for the production of sodium nitrate a substance having the sodium as a cation should react with another substance having the nitrate anion. Moreover, neutralization reactions are carried out when bases react with acids, such is the case of nitric acid and sodium hydroxide:

Thus, the answer is (B) HNO3 + NaOH as the other options involve salts rather than acids or bases as starting reactants.
Regards.
Answer:
<em>The correct option is D) a motile eukaryote</em>
Explanation:
Peroxisomes are structures which are present only in the plant or animal cells. Hence, based on this observation we can easily tell that the organism which is newly discovered is a eukaryote. Both plants and animals are eukaryotes.
Flagella are structures which are thin and hair shaped. Flagella allow movement of a cell, mostly they allow a whip-like movement. Based on this observation we will conclude that the organism discovered is a motile eukaryote.
The half life of a certain substance is being used to date fossils or to know their age. Most likely, it is carbon-14 that is the substance that is being traced in fossils since it is what remains after million of years in a fossil. The half life is important in determining the constant in the decay and, consequently, determining the age of the fossil.
