You are given the molarity of the solution which is 1x10-5 M. Since molarity is moles of solute over liters solution. You could determines the moles.
M=m/V
1x10-5 = m/(2 L)
m = 2x10-5 moles ligand A
We could determine the mass of ligand A by using the molar weight:
2x10-5 mol * 250 g/mol = 0.005 grams of ligand A
I hope I was able to answer your question. Have a good day.
It is an advantage because they approach their environments from all sides equally.
Answer:
C. Late Precambrian era
Explanation:
Eon refers to two or more geological eras forms an eon. Eon is mainly divided into four eon namely Hadean, Archean, Proterozoic and Phanerozoic. Phanerozoic includes Palaeozoic, Mesozoic and Cenozoic era. Cambrian falls under the <em>Palaeozoic era </em>which was the major turning point the evolution period of geological time scale. The sudden increase in many diversity of animal phyla was evolved during this period. Also, the first land plant was appeared in this period which gave a promising fact that plants will grow on the apt seasonal conditions.
It happens when the two groups become sufficiently different and the two can no longer interbreed. A known example of speciation is the London underground mosquito where it formed a new species within the existing genus. There are examples in micro-evolution but not in macro-evolution.
