Answer: the atomic number (number of protons) order the elements.
Explanation: Each element on the Periodic Table has their own configuration of electrons. In order to have a neutral charge, there is an equal number of protons to electrons. Thus, the atomic number (number of protons) order the elements.
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily
<u>Answer</u>: D. calcium chloride
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
Following gastrulation, the next major development in the embryo is neurulation, which occurs during weeks three and four after fertilization. This is a process in which the embryo develops structures that will eventually become the nervous system
Answer: Yes this chemical reaction obeys the laws of physics. Its very simple, let me explain.
Explanation:
When Iron(Fe) oxidizes it gains three oxygen atoms so it reacts to form Fe2O3 so it becomes bigger or explands. Its also sometimes called "oxide jacking".
