Answer:
The evolutionary process at work is best described by option <em>B. gene flow</em>
Explanation:
<em>Gene flow </em>also known as migration is any movement of individuals, and/or the genetic material they carry, from one population to another. If gene versions are carried to a population where those gene versions previously did not exist, gene flow can be a very important source of genetic variation. In this case, the nearby population <em>migrates </em>to the mole population. The diagram is a good description of the <em>Gene flow </em>process.
Moles of ammonium sulfate = 26.42/molar mass of (NH4)2SO4
= 26.42/132.14 = 0.19 mole.
Molarity = moles of ammonium sulfate/volume of solution
= 0.19/50x10^-3
= 3.8M
Answer:
c is right for this question
Explanation:
<span> Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change. 9.</span>
In studying chemistry, one should learn how to read the periodic table and periodic trends in the table.. Of course, you should also know the abbreviations of each element in it so that you can identify what element is in chemical structures. Memorizing and knowing it by heart is the best way. You should also study what we call chemical nomenclature which is naming combinations of elements. Elements when combined may form ionic compounds, bonds or acids. Knowing what element reacts with another will also be necessary that's why the concept of chemical reactions must be further studied.
