Answer:
<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>
Explanation:
During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.
For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
Answer:
Besides hard and soft, conductors and isolators is another group to divide non-living things into two groups.
Explanation:
The general classification is a very hard task to do. However, if we think in absolutes we will be able to find ways to divide non-living things into two groups. Think about one thing, for example, flammable or not flammable, shinny, or opaque. We just need to find a characteristic and them see if we can group non-living things below them.
Answer:
Done!
Explanation:
There is not a problem with the model. The atoms are tightly compacted to get, so if you were to cut it in half the split would also be smooth and straight. For example, a grain of salt is rough on the outside, but when you cut it in half the split is smooth. It is the same with the atoms in the model.
