Prokaryotic cells because they don't have a nuclei.
Answer:
The correct answer is 8 g.
Explanation:
During a physical change, the identity of the substance <u>does not change, because no chemical reaction occurs</u>. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.
<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>
Photosynthesis, the process which uses light energy to power the combination of carbon dioxide and water to form glucose and oxygen.
