Substances that are made up of only one type of atom.
Grounds are located where warm and
cold currents converge, where warm and cold currents meet happens to have
regular foggy conditions, as the overlying warm and cold air come in contact
with each other. They also tend to have high biological productivity, because
plankton growth is encourage by the mixing of warm and cold currents. Some of
the world's most productive fishing.
If the solutions and leaf disks were boiled prior to the photosynthesis I think all the leafs would sink. Photosynthesis would not ensue by the reason the proteins would be converted and not useful.
Alternatively, if the solutions and leaf disks were subjected to very cold temperatures the leaf disk will float faster.
The second one due to the fact that pioneer plants come in much later
