Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.
<u>There are five groups of factors responsible for the kind, rate and extent of soil development. They are: Climate, organisms, parent material, topography and time. Soil from one place is different from another because of the differences in the influence of these factors.</u>
Answer:
Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).
Explanation:
The main difference between a prokaryotic cell and a eukaryotic cell is that the prokaryotic cell have no true nucleus instead its genetic material is just suspended in its cytoplasm termed as nucleoid. The nucleus when viewed under the microscope is a membrane bound which is easily distingushable compared to the nucleoid.
Another distinguishing feature is that prokaryotic cells are usually smaller than eukaryotic cells.
